Ken bailed out so unless someone steps up to take over the LED driver side of the project, we are dead in the water. If someone could source a small OTS LED driver, I could go forward.

I like the idea of the glass lens over plastic because of the heat, and in my case because I'm air compensating the motors it would be quite simple to run extra air lines to the lights. But what I have no idea about is the driver. I followed and the link but the grammar is so bad it's on the verge of incomprehensible. However, but for five bucks I suppose I could burn up a few of these drivers in testing to find out how they work. Due to time constraints I'll probably strap a couple of dive flashlights on the sub for Seneca, and this will be my next little project afterwards.

You can generally run these leds at a lower voltage & it is beneficial to them. If you have a bench top power supply that goes to 36V, you can slowly power up the led without a driver & check if it is bright enough at 36V. Don't do this for more than a second or so or you may destroy the led. I am having a 48V system, but the choices in electronics that are compatible, dramatically drops over a 36V system. I have looked at just about every off the shelf led dc driver on the planet. cheers Alan Sent from my iPad > On 3/07/2016, at 7:03 am, Cliff Redus via Personal_Submersibles wrote: > > This LED driver will not work for the 10K lumen Bridgelux LED as it needs 38V forward voltage , 2.1 amps and 80W.

Hello Psubbers, Yesterday the Pilot Fish hull went down to -255m off the coast in the SE of France. For a long time I have wondered how to pressure test the Pilot Fish hull. There was the Aberdeen Hypobaric center option, but way up in Scotland, and also a test chamber in Cherbourg, France operated by DCNS, closer but much more expensive and requiring loading the hull vertically, so fully stripped out, with a special support. Other option: deep lake. Unfortunately there are not that many options in France with easy access. At last, a deep spot in the sea. Ever wasted time on the internet looking for things like where is the deepest point on the planet or where is the farthest point from land in the ocean? I did some of that, discovered the existence of a mysterious deep cutting canyon (Gouf de Cap Breton) near my town in SW France. But it is narrow and swell is big there. Then the mediterranean sea with Toulon came as natural choice. the depth drops off to 1000m less a few miles from the harbour. And a friend of mine I did my military service with in the area, found the perfect boat (Coquimar) for the job, not too expensive, but only with perfect weather though, and careful preparation. For the last few weeks we were watching weather, and availability of the boat and all people involved. this week the planets aligned so I prepped the sub and drove to Toulon on Wednesday to do the job on Thursday. I had loaded a wooden berth on the back of the rental truck to use on the boat to put the hull, keeping the trailer on shore. So we leave shore at 5h30 on Thursday. Nice weather but a bit foggy. When exiting the harbour, we are contacted by radio by the harbour control tower asking us what we are up to (probably spotted the hull on the deck...). After a short discussion which we cannot escape, we are told to come back as we do not have an authorisation to do the job. We did not know about this and soon discover it normally takes one week to get approval, even when it is the French navy who asks for their exercises... Really bad news. Weather window would close. I have to say that on top of the French administrative complexity, Toulon is where the navy hosts their nuke attack subs, hence the local authorities are looking closely at all underwater activities. (and which is why I did not want to use acoustic pingers on the hull for the test in case of retrieval, just out from the subs hide nest...). And it does not help to tell the authorities we are testing the hull of a british flag registered submersible!! Back to the harbour. To avoid a pricey cancelling of the operation, the only and near impossible hope is to get approval during the day, and test the next day, for which the weather forecast improves. Long story cut short, tens of phone calls later to various offices and people, including cold calling a retired admiral back from the golf course to grease the process, I get a grant at 5pm. So same process the next day. Weather just perfect. See the pics on the facebook page. We even see dolphins. at 6h30 we arrive on location. The boat has a crane just rated over the hull weight. But accounting for dynamic loads due to movement of the crane boom, and suction effects when pulling the hull out, we come close to the rated capacity of the crane, hence the need for a nice weather window with almost no swell. Swell is also not good as a hull low on water can easily bang the boat and fenders are too high to help. And the crane boom cannot reach the winch tie point, so we decided to first crane the sub in the water, having it slightly floating (-50kg) then move the boat to bring the sub on the other side where the winch is, and then, clip some lead weights on the sub's hull to get it to sink for the test. I filled the sub with sand bags and sodalime buckets to make it just buoyant. I check all the through hulls, and add a touch of silicone on the hatch oring. A Scubapro 330m bottom timer is attached on the nose frame. To minimize the use of a diver, we attached 7m long twin ropes at both nose and tail of the hull with a pressure resistant trawler float at the end I got from Emile. This helps orienting the sub, especially when the sub will be coming back up. On each rope, at around 2m from the tie point on the hull and 5m from the float, we clipped a lead weight from the boat's deck and then lowered it in the water. This gave the hull a negative buoyancy of around -50kg. We then lowered the hull with the boat winch. We did a station at 20m for a few minutes to check tension. I had bought 300m of semi static nylon rope in 3 pieces, which could hold the weight of the sub in case it flooded, but not by much margin, so I spent time making special knots which would not lower the overall resistance of the rope by more than 20%. The ropes were marked every 10 and 50m. The usual best practive is to test at 125% of the max operation depth, so in our case we would go at 120m max in the English Channel so needed only 150m. Since our hull is designed for 250m operational depth, (rather than carrying lead we d rather have a thicker hull) and all the conditions were ok, we pushed down to the 250m mark on the rope. We arrived at 250m at 7h10 and waited an hour. Tension was ok, no air bubble. An hour later we started ascending slowly. At around 9am, we saw the sub by transparency. We could grab one float and unclip some lead, but the other float was entangled so we sent the diver to clear the leads and ropes. The sub became buoyant again. Good news, as a sign it did not fill with water. Then the delicate crane operation went ok, the weather still perfect, but we just first checked for boat wake around us. The depth gauge was recovered. Max depth 262m, but that s configured in fresh water so it is actually 255m in the mediterranean. The rope stretch minus knots consumption explains the 5m off the 250m rope mark target. Opening the hatch we check the hatch closely as the mismatch between conning tower diameter and acrylic dome diameter induces massive stress on the dome ring, and hatch flange. We had FEA done for that, but still... We got scared as I saw water in the sub. But soon tasted, it was fresh... relief. Actually I had embarked fresh water bladders to add weight to the hull, and noticed they were leaking due to weight placed on top of them. I once read on psubs emails about bladders that the question is not about whether they could leak but when... the other through hull seem tight. At 11am we are back to the harbour. and at 9pm the sub is back in Pau after a long drive.

My exterior lights run of the 36VDC buss. The voltage range for 36V buss is 30-40vdc, fully discharged to fully charged. If I Iook at the specs on the 10K Lumen Bridgelux, the driving voltage requirement is 35.1V to 40.4 V with 38V as nominal. So I could in theory run this LED array without any driver at all but every time I hit the throttle, the lights would dim. I need a constant current LED driver that holds the current to 2.1 amps. Like you I have been looking for OTS led drivers but have not been able to find one that meets the specs outlined in Ken M. spec and are small enough to fit in as tight enclosure.

I enjoyed the read. Sounds like a minor miracle that the French authorities issued the permit in one day. The admiral must have had some juice! I would have loved to see your face when you opened the hatch and saw water and then again when it turned out to be fresh.

This is not an LED driver as it does nothing but boost the voltage but for those that want to use this 10K Bridgelux LED array on a 24VDC buss, it should work. Modules nature: Non-isolated step-up (Boost) - Rectification: Non-synchronous rectification - Input voltage: 3.5V-35V - Output voltage: 5V-56V (Must ensure that set the output voltage is higher than the input voltage) - Input current: 3A (max), Rated current:2A - Conversion efficiency: 90% - Dimension: 43mm(1.69")*30mm(1.18")*12mm(.47") (about the size of two postage stamps) - - This dimension would easily fit in the 1 atm enclosure I designed and in fact, we may be able to shrink the enclosure even more. I have ordered some to play around with along with the Bridgelux LED http://www.digikey.com/product-search/en?keywords=976-1277-ND To use this on my boat, I would have to rewire my HV box to feed the exterior lights of the regulated 24VDC buss rather than the unregulated 36VDC battery bank but this would be easy. Would be better to get a proper LED driver but this might do until someone sources a small LED driver that fit the spec Ken developed. - - Cliff On Sat, Jul 2, 2016 at 3:05 PM, Alan via Personal_Submersibles < personal_submersibles at psubs.org> wrote: > Cliff, > what voltage are you running on your sub? > You can generally run these leds at a lower voltage & it is > beneficial to them.

Let me know if you find anything.There are drivers available for driving 2 or 3 lights simultaneously, & these lights seem popularfor growing marijuana. Did you say you were mounting these on the inside or outside of your hull?You could always use the square 80W emitters that operate off 32-36V in your housing design.As I have said before, I can't see any point in trying to put the driver in the back of the light housingas these drivers have heat sinks themselves, & the added heat from the led would cook them.Also you could dissipate the heat from the driver straight out the back without the electronics in the way.Cheers Alan From: Cliff Redus via Personal_Submersibles To: Personal Submersibles General Discussion Sent: Sunday, July 3, 2016 3:05 PM Subject: Re: [PSUBS-MAILIST] PSUBS light project status Alan/ALec, ran across this small DC-DC boost converter for $4 on Ebay http://www.ebay.com/itm/222115591904?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT.?

Since my boat hasn't been in the water yet I don't know what voltage drop I'll see at hard throttle, but in my experience the lead foot only comes down on the surface where I don't particularly need dive lights. When dived, the thrusters are just ticking over. Do you know what would happen when the voltage falls below 35.1? If the lights just go a bit dimmer, that might be fine. If its a step function on the other hand and they just go out altogether, then obviously not so good.

Unfortunately there are not that many options in France with easy access. At last, a deep spot in the sea. Ever wasted time on the internet looking for things like where is the deepest point on the planet or where is the farthest point from land in the ocean? I did some of that, discovered the existence of a mysterious deep cutting canyon (Gouf de Cap Breton) near my town in SW France. But it is narrow and swell is big there. > Then the mediterranean sea with Toulon came as natural choice. the depth drops off to 1000m less a few miles from the harbour. And a friend of mine I did my military service with in the area, found the perfect boat (Coquimar) for the job, not too expensive, but only with perfect weather though, and careful preparation. > For the last few weeks we were watching weather, and availability of the boat and all people involved. this week the planets aligned so I prepped the sub and drove to Toulon on Wednesday to do the job on Thursday. > I had loaded a wooden berth on the back of the rental truck to use on the boat to put the hull, keeping the trailer on shore. So we leave shore at 5h30 on Thursday. Nice weather but a bit foggy. When exiting the harbour, we are contacted by radio by the harbour control tower asking us what we are up to (probably spotted the hull on the deck...). After a short discussion which we cannot escape, we are told to come back as we do not have an authorisation to do the job. We did not know about this and soon discover it normally takes one week to get approval, even when it is the French navy who asks for their exercises... Really bad news. Weather window would close. I have to say that on top of the French administrative complexity, Toulon is where the navy hosts their nuke attack subs, hence the local authorities are looking closely at all underwater activities. (and which is why I did not want to use acoustic pingers on the hull for the test in case of retrieval, just out from the subs hide nest...). And it does not help to tell the authorities we are testing the hull of a british flag registered submersible!! > Back to the harbour. To avoid a pricey cancelling of the operation, the only and near impossible hope is to get approval during the day, and test the next day, for which the weather forecast improves. Long story cut short, tens of phone calls later to various offices and people, including cold calling a retired admiral back from the golf course to grease the process, I get a grant at 5pm. > So same process the next day. Weather just perfect. See the pics on the facebook page. We even see dolphins. > at 6h30 we arrive on location. > The boat has a crane just rated over the hull weight. But accounting for dynamic loads due to movement of the crane boom, and suction effects when pulling the hull out, we come close to the rated capacity of the crane, hence the need for a nice weather window with almost no swell. Swell is also not good as a hull low on water can easily bang the boat and fenders are too high to help. And the crane boom cannot reach the winch tie point, so we decided to first crane the sub in the water, having it slightly floating (-50kg) then move the boat to bring the sub on the other side where the winch is, and then, clip some lead weights on the sub's hull to get it to sink for the test. > I filled the sub with sand bags and sodalime buckets to make it just buoyant. I check all the through hulls, and add a touch of silicone on the hatch oring. A Scubapro 330m bottom timer is attached on the nose frame. > To minimize the use of a diver, we attached 7m long twin ropes at both nose and tail of the hull with a pressure resistant trawler float at the end I got from Emile. This helps orienting the sub, especially when the sub will be coming back up. On each rope, at around 2m from the tie point on the hull and 5m from the float, we clipped a lead weight from the boat's deck and then lowered it in the water. This gave the hull a negative buoyancy of around -50kg. > We then lowered the hull with the boat winch. We did a station at 20m for a few minutes to check tension. I had bought 300m of semi static nylon rope in 3 pieces, which could hold the weight of the sub in case it flooded, but not by much margin, so I spent time making special knots which would not lower the overall resistance of the rope by more than 20%. The ropes were marked every 10 and 50m. > The usual best practive is to test at 125% of the max operation depth, so in our case we would go at 120m max in the English Channel so needed only 150m. > Since our hull is designed for 250m operational depth, (rather than carrying lead we d rather have a thicker hull) and all the conditions were ok, we pushed down to the 250m mark on the rope. We arrived at 250m at 7h10 and waited an hour. Tension was ok, no air bubble. An hour later we started ascending slowly. At around 9am, we saw the sub by transparency. We could grab one float and unclip some lead, but the other float was entangled so we sent the diver to clear the leads and ropes. The sub became buoyant again. Good news, as a sign it did not fill with water. Then the delicate crane operation went ok, the weather still perfect, but we just first checked for boat wake around us. > The depth gauge was recovered. Max depth 262m, but that s configured in fresh water so it is actually 255m in the mediterranean. The rope stretch minus knots consumption explains the 5m off the 250m rope mark target. > Opening the hatch we check the hatch closely as the mismatch between conning tower diameter and acrylic dome diameter induces massive stress on the dome ring, and hatch flange. We had FEA done for that, but still... > We got scared as I saw water in the sub. But soon tasted, it was fresh... relief. Actually I had embarked fresh water bladders to add weight to the hull, and noticed they were leaking due to weight placed on top of them. I once read on psubs emails about bladders that the question is not about whether they could leak but when... the other through hull seem tight. > At 11am we are back to the harbour. and at 9pm the sub is back in Pau after a long drive.

The light intensity and current are strong functions of the forward voltage. When the driving voltage drops from 38 to 35.1 vdc, the lumens drop from 10,590 to 2846(27%) and the current drops from 2.1 amps to 500mA. So as you start dropping the forward voltage the light get dimmer and dimmer. My guess is the below 35.1, it just continues to get dimmer and dimmer. We really need a LED driver like the one Ken specified that will hold a fixed current regardless of dropping supply voltage.

It's on the sub list as Harold. Before I bought Harold I spent a lot of time designing and making LED based canister dive lights. These 50w bulbs, as others have discovered, make great flood lights. The bulbs and drivers are pretty cheap from China, but it usually tales a month before they arrive. Chinese dive lights can be had cheap if you buy it without the battery. I found the flat blurbs fit pretty well, but you have to machine off all the extra stuff. Couple of years ago I picked up a $1500.00 mini mill at an estate sale for $50.00. That and a mini lathe makes it all work. ?

I have a dozen of those big square Chinese leds alongwith a dozen different drivers, & have destroyed a few of both playing round.You can wind up the voltage & there is a point where you get a fare bit oflight from them; but the amp - Volt gradient can skyrocket with the applicationof just 1 more volt. That's why you need a constant current driver.To check the leds I quite often connect them straight to a bench top power supply & crank upthe voltage till they glow, but only for a second.I pressure tested an led the same as you have to 2000psi & it survived.Cheers Alan From: via Personal_Submersibles To: via Personal_Submersibles Sent: Tuesday, July 5, 2016 6:57 AM Subject: Re: [PSUBS-MAILIST] =?utf-8?q?PSUBS_light_project_status?= Well duh ? this conversation got me thinking.

For my video lights I mount the driver in the battery box. I've also potted the bottom of the light as I don?t trust canister light glands at depth. For Harold I'll mount the driver internally.

I've made several of these the last couple of years for underwear video lights. I'll also post it to my psubs project page. Basically I took a Chinese dive light,? turned a plug to replace the battery tube and then turned an aluminum cylinder to mount the flat LED - functioning as a heat sink. For my video lights I mount the driver in the battery box. I've also potted the bottom of the light as I don?t trust canister light glands at depth. For Harold I'll mount the driver internally.

In that case the thermistor will shut the LEDs off at 70C, let cool and turn back on cycling. Doesn?t take much talent like learning to weld, only a little longer.

The remainder of the parts should not see much more than about 45C. The LM239 should stay about 5 degrees above the ambient. It?s one of the lowest temperature rise parts on the design.

The sub is good and stable, its just getting in and out. I think your boat will be much better. You can stand on the deck and jump in at a suitable moment. Leaving the crane still attached is a good ideas as well as you get in and out. If something did go wrong, the boat wouldn't sink at least. Sounds an interesting dive.

But there is no other plans I know of.

Once this tank has been removed, it is possible for a second person to lie prone on the floor of the hull (with legs bent at the knees and feet toward the top of the aft bulkhead) with the pilot seated above passenger (head in dome and feet placed on both sides of passenger's torso). It's cramped for sure, but you can work it out. Snoopy is a good example of a K-250 that has been modified to accommodate a second occupant. Another great modification to Snoopy is her saddle tanks (much as you inquired), unfortunately they were an Alec Smyth custom job and not detailed in the plans. You can see the saddle tank construction detailed at the link below. ~ Doug S. http://www.psubs.org/projects/1234567810/snoopyin2012/ On Sat, Jul 16, 2016 at 2:41 AM, Kamil ?ebrowski < personal_submersibles at psubs.org> wrote: > Hi, > > Thank you for a nice welcome.

Not so so Much Psubers in Europe. There is a another two seater in Potsdam near Berlin. Reinhards Nemo II. And yes one one man and one fife man in Rostock. Before you build something in real steel maybe go Berlin - Rostock - Amsterdam to get some input. Just to purchase some drawings and than convert to someting else make not so much sence for a custom build. First step should be a requirement list. How many persons ? Which range in which time? Dive deep. Seaworthy or lakes, co caves or all? Undependly orwith a support boat ? And so on. A sub for the baltic will look complete different from a cave diver. Berlin:Reinhards 2 Seater with saddle tanks https://www.youtube.com/watch?v=gf4DS0r6n44 Rostock:My boats. One man 0,5 t with sadlle tanks and for sale, second unita is a 70ts Offhsore with diver chamber and for and aft tanks https://www.youtube.com/watch?v=CYaTaWY0dhg https://www.youtube.com/watch?v=aRv2Ri4FmiY Near Amsterdam: Emiles 3 Seater with Saddle tanks https://www.youtube.com/watch?v=B2975eaBmYs On a 1-3 Seater I prefer sattle tanks.

I would describe a K250 as a big hole in the water waiting to fill up whenever the hatch is open, but I agree Emile's boat is something entirely different. Also, in my experience there is a huge difference between boarding one person or two. If it's just me, I can time it better and slam the hatch right behind me, but if there's someone inside the sub before I get in, it slows down the move a lot and makes me a whole lot more worried about the consequence of a mishap. I can quite see a situation where a two person load would be too dangerous but a one person dive might still be accomplished. ?Best, Alec ?On Fri, Jul 15, 2016 at 12:09 PM, Alan via Personal_Submersibles wrote:Emile,we abandoned a dive in Snoopy 4 miles off the Florida Coast in what didn't seem like big seas.It looked too dangerous to board.

'Manned Submersibles' is an awesome resource as well, kudos to you for your willingness to do research prior to starting your first build. Without trying to sound discouraging, I want to say that to me, the goals you outlined in a previous email seem quite ambitious. If you have the financial means, time/space and necessary fabrication skills, anything is possible, but for many of us, we're on a "budget" when it comes to all of those things, so you may find that your dream sub is not practical as a first build. In my opinion, a K-350 would be a great project for you to start with, then work your way to a larger sub. Just my thoughts... Doug S.

The k250 and k350, and most of the members self designed subs are meant to be trailerable. I have a ford f350 truck with a towing capacity of ~10000 pounds. Subtracting a probable trailer weight of 1000lbs, that leaves a max sub weight of 9000lbs. In a sub cabin volume and total weight are directly correlated, since it must be neutrally buoyant. That means that the biggest sub practically trailerable at 9000lbs has a cabin displacement of ~144 cubic feet (only 4 cubic meters) Or only a little bigger than two phone booths!!! This theoretically limits most psubs to 2 passengers at the most.

There is a another two seater in Potsdam near Berlin. Reinhards Nemo II. And yes one one man and one fife man in Rostock. Before you build something in real steel maybe go Berlin - Rostock - Amsterdam to get some input. Just to purchase some drawings and than convert to someting else make not so much sence for a custom build. First step should be a requirement list. How many persons ? Which range in which time? Dive deep. Seaworthy or lakes, co caves or all? Undependly orwith a support boat ? And so on. A sub for the baltic will look complete different from a cave diver.

It very much depends on the skills you currently have and the machinery available to you. If you are a fabricator with decent skills and a "fully loaded" machine shop, you could probably do a K-350 for $12,000 - $20,000 (depending on local availability of steel and your thriftiness in buying other parts). If you lack fab skills/access to a shop you will need to hire some of the work out and this will increase the cost of the build significantly (perhaps to the $35,000 - $50,000 range). Any way you slice it, if you are building a sub it's going to mean some combination of sweat and money. In my opinion the best thing to do is split the project into several stages - like Pressure hull, Ballasting system, Propulsion, Cabin, Exterior - Then start with basic pressure hull and don't worry about anything else until the basic pressure hull is complete. Just my idea... Doug S. On Sun, Jul 17, 2016 at 2:27 PM, Kamil ?ebrowski < personal_submersibles at psubs.org> wrote: > I am sound like a newbie. So the best starting point is K-250, K-350?

I'd imagine that the laws are similar in many other countries though - as soon as a vessel is mechanically powered it has to be registered. As far as certification, the K-350 design is certified by both Lloyds and Nippon, But most sub owners don't worry about becoming certified because of the costs involved with testing/inspection. An actual certification is only "valuable" when you plan to put the sub to work commercially (at least that's my understanding - it's a pretty costly procedure). For private use no certification should be necessary. ~ Doug S. On Sun, Jul 17, 2016 at 5:11 PM, Kamil ?ebrowski < personal_submersibles at psubs.org> wrote: > The ?20,000 is a acceptable cost.

Then you will know what you are looking at if you take a tour of European submersibles. If you choose a design with a large acrylic dome, talk to Emile first as he is your only economical option for a dome that I know of. And you may have to go with a size he has a mould for.

He is most comfortable with soildworks. From what I have found, ABS doesn't care about the CAD program as long as it shows what they need. I found out I will not need a FEA on the hull done, so I don't have to worry about that. I am working on purchasing the CAD program, but am wanting some input on what I should buy exactly. The functions I need it to preform are: *Loading stress on frame *Weights and Balance *General design modeling for new design *Printing of blueprints from the design that we can fabricate from My first question is there any other functions I am missing? My second question is what exactly should I buy from solidworks?

Then they visit your factory to see if it is up to standard& visit at various stages. They want to know the composition of every nut & bolt you use, where they came from& whether the factory that made them had certification. They want to know who you have doing any of the workand what their qualifications are. I won't give more detail, as will be typing all day, but it ends in the final dive test.If you want to know any more ask. I?think I?have a brief summary of the rules somewhere.Alan From: Kamil ?ebrowski via Personal_Submersibles To: Personal Submersibles General Discussion Sent: Wednesday, July 20, 2016 7:31 AM Subject: Re: [PSUBS-MAILIST] Sub for 2 pexople Anyone know how that inspection looks like from Lloyds?

Most test can be done by the owner/builder and third parties. Also SL accept test by other Classifikations. So you can make a pressure test of the hull with DNV-GL or T?V or Dekra, Dome Test with ABS, SL factory test and measurings like from Emiles domes. etc. Other class normaly accept only there own tests. You have also to show your drawings, material certificates etc., pressure and stability calculations etc. But Swis Lloyds for example accept also pressure test in the natur/lake/open sea or in pressure boilers designed for other purpose. The supervisor will only come may two times. At the beginning of construction/design to guide you to the basic rules and during the first operational trails.During this first meeting the supervisor will decide if the sub concept has the possibility to get a Saftey Certificate or not. A sub with blows his ballast tanks with propane out or were the passenger can not reach the emergency blow valve - will maybe not get under the process.. You have to write a own Manual and handbook about the sub which contains all technical and practical information about your sub and handling. This final acceptance test will include check of all system, special the emergency systems like emergency bouy, drop weights, Life support system, but also a simple stability test. All test in a reduce and very practical way that you can do it on a simple way. For example drop plate test with the sub on a forklift or hangar crane with a bed madress below. SL cost a fraction of the big class cost - about 8000 euros for a small 1-3 seater. But most paperwork has to be done by yourself. By the way SL accept not second hand propane tank subs with unkown tickness made from unkown material. SL works only build in the european community. You get an building certificate that the sub pass all test and that the sub and equipment is safe to operate with passengers. The technical rules are maybe 98% the same as on any other classification. So if you build technical to the DNV:GL or ABS or LR rules we are fine with that. Just the administraton work with the agency is reduce to the minimum or better the boats size. In case you want to use the sub only for yourself and your friends - no classification is required at all. Safe the money. You need the papers if you like to insurance you sub. Or maybe to sell it commercial. SL offer this service - not because it is a business but it is maybe the only way that a homebuild or smal company build get a saftey certificate inside a homebuild budget. Hope this help.

DNVL is the World's biggest certifier of submarines & is based in Hamburg. It would probably cost you US $80 - $100,000 to go through the certification process. Then there is the ongoing costs of yearly inspections, with a major inspection after 5 years. Only useful if you are using a submarine commercially, a lot of their guidelines can be used without paying $100,000. Carsten, who is in Rostock Germany, was offering a certification process under Swiss Lloyds. This was aimed toward amateur builders & offers an economical process. The DNVL process is that you go in to a contract, & they give you technical advice for design. Designs for the various parts (hull, electrical, ballasting, stability, life support) are submitted for approval. It costs about US30,000 to get to design approval. Then they visit your factory to see if it is up to standard & visit at various stages. They want to know the composition of every nut & bolt you use, where they came from & whether the factory that made them had certification. They want to know who you have doing any of the work and what their qualifications are. I won't give more detail, as will be typing all day, but it ends in the final dive test. If you want to know any more ask. I think I have a brief summary of the rules somewhere.

Even if the drawings have a stamp - somebody has to check if you build according to it. SL not required a 2 or 5 years or so check. Only new checks/inspections if you rebuild the boat in major parts. Maintance is not in the scope. Its a Saftey BUILDING Certificate. If you rebuild the boat after some years without a SL check - your building certificate lost his use. Thats all.

My last one take 12 years.. - Place..at least a garage, better a double one - Tools., crane, a good light welder, tables, rollers, eyerthing to move, roll and lift 2-3 ts - Expierence in build someting in metal.. - Subcontractors to make something you can not make yourself. (Some of the guys here build everything themself as part of the travel.) (But Emile has small specalist company for small subs which can build any sub part you not like to make yourself in high quality, Domes, motors, scrubbers, GRP work, Tanks, light etc. And because it is a oneman show company it is relative unexpensive.) - a good four wheels driven car Defender class and a trailer. Its an adventure. But some here in the group goes this way more than one time. Seems they had fun with it and did it again and again. A K350, K250 is a good starter, because relative simple design and cheap design. And outdate. The Eurosub / Javasub / Nordicsub has more space, view, better seagoing and overall performance. But its more advanced and take more time and money to make. Take a K350 Hull plans, safe the pressure hull calculation and design a new sub around is a way some guys here are going. vbr Carsten - were do you life in Poland?

I am considering having 2 valves on each ballast tank, top & bottom. I would just run a wire from the coil on one valve to the coil on the next to operate them simultaneously with one through hull. It is a matter of getting the right thickness of wire & number of turns, to get enough magnetism to pull the valve plungers open.

High vacuum grease, if used, is not intended as a fluid thrust bearing (it is not completely encapsulated by seals), nor as a seal in of itself, but rather to provide thin-film lubrication to enable the acrylic surface to slide against the seat as it deflects under pressure, to prevent localized creep or fretting at the interface surface. As with all thin films, you need add only enough grease to make the surfaces shiny - excess grease will be extruded anyway. Air bubbles are really only a cosmetic problem, provided the encapsulating surfaces surrounding the bubble remain lubricated . The seal is generally outboard, so it is just the thrust load squeezing the bubbles, and they will either compress and return, or simply be extruded out. You can try assembling the window into the seat under vacuum to minimize them (no air, no air bubbles), in conjunction with minimizing the amount of grease. If you have scratches on the bearing surface, the grease only helps insofar as it allows the window surface to slide over the scratch as it moves. A deep / wide scratch may allow the acrylic to creep and locally deform at that location, allowing it to get hung up as the rest of the window moves. This will probably manifest itself as a particularly creaky window. Use Dow-Corning High Vacuum Grease, applied under clean conditions to cleaned surfaces using a gloved hand or lint-free applicator, and wipe away excess grease before mating the window.

As the applied force increases, the pressure within the lubricant film increases, and as this exceeds the viscous friction within the fluid, it will just extrude out the open end until the window is sufficiently supported by the metal of the window seat, or the reduced clearance increases the viscous friction in the fluid to match the applied forces. When you have bubbles, your fluid is a heterogeneous mixture of air and grease, but it is all at the same pressure, so it offers the same support to the window (if the bubbles are not open to atmosphere at the edges). The acrylic doesn't care whether air or grease is providing the support. The window isn't really floating on the fluids though, except possibly at low external pressures where the viscous friction in the grease is sufficient to hold it in place against extrusion. Under higher pressures, the thin film lubrication layer is only nanometres thick where the window is actually making contact with the peaks of the metal bearing surface, and that contact area increases with increased pressure. Having the grease film just allows the acrylic to deflect radially in response to load, instead of building larger internal stresses near the mating surfaces. You can use such windows without grease at all, but they will have higher friction at the interface, and thus creak more as the higher stresses are built up and relieved when radial forces exceed the coefficient of friction. With gaskets, there is typically no relative movement at the mating surfaces, and it is the gasket that deforms to accommodate the relative movement.

Stevenson via Personal_Submersibles wrote: The window is not really supported by the grease. As the applied force increases, the pressure within the lubricant film increases, and as this exceeds the viscous friction within the fluid, it will just extrude out the open end until the window is sufficiently supported by the metal of the window seat, or the reduced clearance increases the viscous friction in the fluid to match the applied forces. When you have bubbles, your fluid is a heterogeneous mixture of air and grease, but it is all at the same pressure, so it offers the same support to the window (if the bubbles are not open to atmosphere at the edges). The acrylic doesn't care whether air or grease is providing the support. The window isn't really floating on the fluids though, except possibly at low external pressures where the viscous friction in the grease is sufficient to hold it in place against extrusion. Under higher pressures, the thin film lubrication layer is only na! nometresthick where the window is actually making contact with the peaks of the metal bearing surface, and that contact area increases with increased pressure. Having the grease film just allows the acrylic to deflect radially in response to load, instead of building larger internal stresses near the mating surfaces. You can use such windows without grease at all, but they will have higher friction at the interface, and thus creak more as the higher stresses are built up and relieved when radial forces exceed the coefficient of friction.? With gaskets, there is typically no relative movement at the mating surfaces, and it is the gasket that deforms to accommodate the relative movement.Sean On July 21, 2016 9:51:58 AM MDT, hank pronk via Personal_Submersibles wrote: Sean,Thank you, you are the man! ?I probably had to much grease, but that aside, if there are air?bubbles, would that not impact the load bearing. ?The point location of the bubble will not support the port. ?It is with that logic that I assumed a super fine scratch would not impact the load bearing capacity. ?Yes I was hoping the grease gods would off set my fine scratches. ??Hank On Thursday, July 21, 2016 9:39 AM, Sean T. Stevenson via Personal_Submersibles wrote: In general, you want a 64 microinch finish on all window seat bearing surfaces, except for if you are using bearing gaskets in which case 125 microinch surface finish is acceptable where the gaskets are. High vacuum grease, if used, is not intended as a fluid thrust bearing (it is not completely encapsulated by seals), nor as a seal in of itself, but rather to provide thin-film lubrication to enable the acrylic surface to slide against the seat as it deflects under pressure, to prevent localized creep or fretting at the interface surface. As with all thin films, you need add only enough grease to make the surfaces shiny - ex! cessgrease will be extruded anyway. Air bubbles are really only a cosmetic problem, provided the encapsulating surfaces surrounding the bubble remain lubricated .? The seal is generally outboard, so it is just the thrust load squeezing the bubbles, and they will either compress and return, or simply be extruded ! out. Youcan try assembling the window into the seat under vacuum to minimize them (no air, no air bubbles), in conjunction with minimizing the amount of grease.If you have scratches on the bearing surface, the grease only helps insofar as it allows the window surface to slide over the scratch as it moves. A deep / wide scratch may allow the acrylic to creep and locally deform at that location, allowing it to get hung up as the rest of the window moves.? This will probably manifest itself as a particularly creaky window.Use Dow-Corning High Vacuum Grease, applied under clean conditions to cleaned surfaces using a gloved hand or lint-free applicator, and wipe away excess grease before mating the window.Sean On July 20, 2016 10:27:53 AM MDT, hank pronk via Personal_Submersibles wrote: Hi Sean,I have a couple questions. ?Can I assume that grease trapped in super small scratches in the port seat will carry the load of the acrylic. ?These are swirls left after sanding and polishing the seat. ?How much grease do I actually put on the seat? ?When I grease the seat with a very thin layer, air gets trapped in small bubbles even when I rotate the port. ?I have seen these marks in the grease in pictures of other subs with conical ports. ?Are those air bubbles a problem or will they squeeze out under pressure?Thanks'SeanHank Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles -------------- next part -------------- An HTML attachment was scrubbed...

The good news is the trailer and boat systems seem to be good, and the cabin and battery pods were watertight. The bad is she had a static stability issue and will require considerable additional ballast weight. I have a stability spreadsheet, which indicated a righting moment of 11200 in-lbs in standard configuration. However, when I factor in a few very normal circumstances (no crewman lying on the floor, captain standing up, hatch raised because its open) it drops to a puny 460 in-lbs. That was a bad design oversight on my part but should be easy to correct with additional ballast. I'll need to add buoyancy as well, which is more challenging, in order for the sub to remain neutrally buoyant when submerged. So, not ready yet and I'm afraid I'll be sub-less at the convention, but at least my presentation should be a bit more interesting. Lesson learned... when launching a sub for the first time, do so with the hatch sealed and nobody inside. I launched as if it were an already proven sub, and things got rather too exciting because she turned out to be woozy and I was standing in the hatch. We managed to avert flooding, but it was way too close for comfort.

Interesting report. There probably isn't a single psubber who has had a perfect first launch and like you say, hopefully it should be relatively easy to correct. Lots of positives and at least you managed to avert a flood, that would be a proper nightmare. Have you got any pics? Or are you saving them for the convention? Actually, are the talks going to be streamed like last year? Or at least recorded? I would like to watch them as always. Also, the stability spreadsheet you mentioned. Is that a public thing? or your own? Could I have a copy?

The good news is the trailer and boat systems seem to be good, and the cabin and battery pods were watertight. The bad is she had a static stability issue and will require considerable additional ballast weight. I have a stability spreadsheet, which indicated a righting moment of 11200 in-lbs in standard configuration. However, when I factor in a few very normal circumstances (no crewman lying on the floor, captain standing up, hatch raised because its open) it drops to a puny 460 in-lbs. That was a bad design oversight on my part but should be easy to correct with additional ballast. I'll need to add buoyancy as well, which is more challenging, in order for the sub to remain neutrally buoyant when submerged. So, not ready yet and I'm afraid I'll be sub-less at the convention, but at least my presentation should be a bit more interesting. Lesson learned... when launching a sub for the first time, do so with the hatch sealed and nobody inside. I launched as if it were an already proven sub, and things got rather too exciting because she turned out to be woozy and I was standing in the hatch.

I remember going over this when I did my hatch port. Similar although not to the same spec as yours. The viewport was made by Stanley Plastics and there was a very small "flat" on the high pressure edge. Not a chamfer as such, just a flat bit. So I used this small gap to put an O ring in and then put an epdm gasket between the steel retaining ring and port. Took up the space on the seat side with a cork gasket. It seems to work ok although I haven't tested it to any great pressure. Hope pic makes it through. ?

Plus the o-ring at that location is the modern standard for low pressure seals. Your gasket on top arrangement is not actually necessary, nor is it common. At depth, the acrylic to metal interface provides the seal. And yes, that would be the first of the Nekton series on page 275. When the order for the next pair of subs came along, the designer added Alpha to the first sub's name to differentiate from the newer boats (Beta & Gamma, and eventually, Delta). ABS was disinclined to allow the turret, as it was called, and it had turned out in any case to be less operationally useful than was originally hoped as the observer's weight shifted that far forward caused trim problems. It worked fine, however. In fact, it is still working fine to this day, as the sub is kept in pristine and dive ready condition by its current owner--in its original design configuration, I might add, with minor upgrades. You don't mess with success. Were I building one today, it would have standard configuration (Perry style/your style) viewports, but I'm not sure that I would change much of anything else. They were and are truly the most successful Deep Jeep, simple, inexpensive, light weight, and pretty much bullet proof. That's a hard combination to beat.

Plus the o-ring at that location is the modern standard for low pressure seals. Your gasket on top arrangement is not actually necessary, nor is it common. At depth, the acrylic to metal interface provides the seal. And yes, that would be the first of the Nekton series on page 275. When the order for the next pair of subs came along, the designer added Alpha to the first sub's name to differentiate from the newer boats (Beta & Gamma, and eventually, Delta). ABS was disinclined to allow the turret, as it was called, and it had turned out in any case to be less operationally useful than was originally hoped as the observer's weight shifted that far forward caused trim problems. It worked fine, however. In fact, it is still working fine to this day, as the sub is kept in pristine and dive ready condition by its current owner--in its original design configuration, I might add, with minor upgrades. You don't mess with success. Were I building one today, it would have standard configuration (Perry style/your style) viewports, but I'm not sure that I would change much of anything else. They were and are truly the most successful Deep Jeep, simple, inexpensive, light weight, and pretty much bullet proof. That's a hard combination to beat.

Its the normal ports I had to put the cork bit on. So the epdm gasket goes right across. I have Stachiws book here at work for quick reference, so checking page 353...yes, its almost the same. Except I put the O ring into the little gap. The gap was unintentional and it just arrived like that when I got it from Stanleys. But it fitted an O ring perfectly. Oh well, it seems ok. I just noticed, page 275, is that Gamma? Suspect its one of the others. And some odd looking square ports on that forward view tower, if that's what it is.

PVHO-1 2012 allows for either the gasket or the o-ring seal between the high pressure face and the retaining ring, but if you opt for the gasket as the face seal, the retainer must precompress the gasket to ensure a minimum of 0.01 in (0.25 mm) compression of the gasket between the retaining ring and the face of the axially displaced window AT DESIGN PRESSURE. No adhesives should be necessary, but you might have to calculate your anticipated axial displacement of the window to ensure that you meet the compression requirement at depth. Seal ring grooves are specifically prohibited on any window surface, but may be machined into non-bearing seat surfaces. I think a radial o-ring seal to the outer cylindrical surface of a truncated conical frustum is permissible (groove in cylindrical surface of seat), provided that sufficient compression of the o-ring still exists as the window deflects at design pressure. Gasket compression by the retainer ring must be uniform, differing by no more than 25% between bolt locations and midway between bolt locations. Gasket hardness is only controlled for bearing gaskets. Your seal gasket can be anything that meets your requirements.

I think there is some discussion of gasket hardness and thickness if using a bearing gasket. I don't recall offhand though.

Stevenson via Personal_Submersibles Sent: Saturday, 30 July 2016 4:04 a.m. To: Personal Submersibles General Discussion Subject: Re: [PSUBS-MAILIST] conical port seal Hank - sorry for the delay but I had to check. PVHO-1 2012 allows for either the gasket or the o-ring seal between the high pressure face and the retaining ring, but if you opt for the gasket as the face seal, the retainer must precompress the gasket to ensure a minimum of 0.01 in (0.25 mm) compression of the gasket between the retaining ring and the face of the axially displaced window AT DESIGN PRESSURE. No adhesives should be necessary, but you might have to calculate your anticipated axial displacement of the window to ensure that you meet the compression requirement at depth. Seal ring grooves are specifically prohibited on any window surface, but may be machined into non-bearing seat surfaces. I think a radial o-ring seal to the outer cylindrical surface of a truncated conical frustum is permissible (groove in cylindrical surface of seat), provided that sufficient compression of the o-ring still exists as the window deflects at design pressure. Gasket compression by the retainer ring must be uniform, differing by no more than 25% between bolt locations and midway between bolt locations. Gasket hardness is only controlled for bearing gaskets. Your seal gasket can be anything that meets your requirements. Sean On July 27, 2016 9:14:43 PM MDT, hank pronk via Personal_Submersibles wrote: Okay, I will not machine a groove in the face, it does seem bad. I am in Canada, so ice is a reality also. I think I will keep it simple and stick with the gasket--that is acceptable and common. I will try to resend the picture and you guys can see what I am talking about. Brian, I think I read that it is bad to put a groove in the seat, also it would be pretty tricky at this point. I finally have a real nice seat that I am totally happy with. I got some pointers from karl Stanley that have worked well. I was over thinking it as usual. lol Hank On Wednesday, July 27, 2016 8:38 PM, Sean T. Stevenson via Personal_Submersibles wrote: I would not machine a groove in the conical face of the port. Instead, use the chamfer on the outer face, and squeeze a ring between that, the seat, and the retaining ring. Sean On July 27, 2016 7:24:18 PM MDT, hank pronk via Personal_Submersibles wrote: Hi Sean, Yes I did email it-- it is actually a picture from the Stichiw book, and is considered an acceptable option. I bet if I read it again I will find the spec for the seal. Personally I like the idea of an o-ring in the port. I always though that was bad, but I would sure prefer that. Today I came across a section in the Stachiw book showing a test sample port with a o-ring groove. It said there was no cracking initiated from the groove because it was close to the high pressure face of the port. Maybe I should chuck her up and machine a grove in it. What do you think a! bout an o-ring. Hank On Wednesday, July 27, 2016 7:07 PM, Sean T. Stevenson via Personal_Submersibles wrote: Did you email it? I don't see it. I'd be inclined to stick with the PVHO recommendations (or Stachiw's book) for sealing arrangements. I think there is some discussion of gasket hardness and thickness if using a bearing gasket. I don't recall offhand though. A conical frustum window will probably use an o-ring though.

Sean On July 27, 2016 3:10:03 PM MDT, hank pronk via Personal_Submersibles wrote: Hi Sean, I am trying decide the simplest way to create my low pressure seal on my conical window. I has a rubber gasket with silicone originally. I did that so when the acrylic compresses the silicone will drag the gasket along for the ride. I don't think it will compress much because it so oversized for the depth. I am wondering now if a thicker softer gasket is better. The gasket would be compressed by the retaining ring. If the acrylic does compress, the gasket can expand to maintain the seal in the event that the sub reaches the surface before the acrylic has expanded. Do you have a recommendation.
