We hired it to use ourselves at great expense, and the thing weighed a couple of hundred kilos, was very solid. The fitter who did the job was very experienced machinist (but hadn't used one before) but could not get the finish very smooth - I can't find photos sorry, but it was like regular machining grooves but much larger - and it looked pretty ordinary. He spent several hours with a grinder cleaning it up. On balance, it probably would have been easier to just flatten it manually with a grinder (but it was on a live liquefied natural gas plant and they don't like sparks:) ). Wasn't critical to get a flat face as we were just making room for a gasket in a slot to have more compression. After getting it pretty flat with a straight edge, the fine stuff/quality control could be done by a thin layer of paint on a known flat plate or machined flange which you put on the welded flange and then where there is no paint deposited, you know that area is too low. Obviously paint is no good, but colored oil or 2-layered carbon paper (nice because then you have a trace of it) would probably work, or charcoal.

We hired it to use ourselves at great expense, and the thing weighed a couple of hundred kilos, was very solid. The fitter who did the job was very experienced machinist (but hadn't used one before) but could not get the finish very smooth - I can't find photos sorry, but it was like regular machining grooves but much larger - and it looked pretty ordinary. He spent several hours with a grinder cleaning it up. On balance, it probably would have been easier to just flatten it manually with a grinder (but it was on a live liquefied natural gas plant and they don't like sparks:) ). Wasn't critical to get a flat face as we were just making room for a gasket in a slot to have more compression. After getting it pretty flat with a straight edge, the fine stuff/quality control could be done by a thin layer of paint on a known flat plate or machined flange which you put on the welded flange and then where there is no paint deposited, you know that area is too low. Obviously paint is no good, but colored oil or 2-layered carbon paper (nice because then you have a trace of it) would probably work, or charcoal.

We lapped on a glass plate because it's smoother than plate steel. You change the glass every so often because as abrades it loses its flatness. There's no trouble knowing if the piece you're lapping is done or if its flat. What happens is that, as you work it, you can see the difference in the surface finish. The new finish gradually spreads across the surface, and when its uniform you know you've got rid of any low points. I really can't imagine lapping something as big as we're talking about here, although I suppose its technically possible. This was really hard work, taking days on end to do a piece that was maybe 6" by 10", tiny compared to what we're talking about here. Greg Cottrell told me he finished his hatch land surface with an angle grinder, using a flap wheel and a lot of patience. It looks like it had been machined.

We hired it to use ourselves at great expense, and the thing weighed a couple of hundred kilos, was very solid. The fitter who did the job was very experienced machinist (but hadn't used one before) but could not get the finish very smooth - I can't find photos sorry, but it was like regular machining grooves but much larger - and it looked pretty ordinary. He spent several hours with a grinder cleaning it up. On balance, it probably would have been easier to just flatten it manually with a grinder (but it was on a live liquefied natural gas plant and they don't like sparks:) ). Wasn't critical to get a flat face as we were just making room for a gasket in a slot to have more compression. After getting it pretty flat with a straight edge, the fine stuff/quality control could be done by a thin layer of paint on a known flat plate or machined flange which you put on the welded flange and then where there is no paint deposited, you know that area is too low. Obviously paint is no good, but colored oil or 2-layered carbon paper (nice because then you have a trace of it) would probably work, or charcoal.

We lapped on a glass plate because it's smoother than plate steel. You change the glass every so often because as abrades it loses its flatness. There's no trouble knowing if the piece you're lapping is done or if its flat. What happens is that, as you work it, you can see the difference in the surface finish. The new finish gradually spreads across the surface, and when its uniform you know you've got rid of any low points. I really can't imagine lapping something as big as we're talking about here, although I suppose its technically possible. This was really hard work, taking days on end to do a piece that was maybe 6" by 10", tiny compared to what we're talking about here.

We lapped on a glass plate because it's smoother than plate steel. You change the glass every so often because as abrades it loses its flatness. There's no trouble knowing if the piece you're lapping is done or if its flat. What happens is that, as you work it, you can see the difference in the surface finish. The new finish gradually spreads across the surface, and when its uniform you know you've got rid of any low points. I really can't imagine lapping something as big as we're talking about here, although I suppose its technically possible. This was really hard work, taking days on end to do a piece that was maybe 6" by 10", tiny compared to what we're talking about here. Greg Cottrell told me he finished his hatch land surface with an angle grinder, using a flap wheel and a lot of patience. It looks like it had been machined.

Obviously I hope we all do everything conceivable to design the flooded sub scenario out of existence; bullet proof hull, oversized soft ballast, hard drop weights, jettisonable propellers, guarded ports/penetrators, strobe light, comms, 72 hours emergency life support... This facemask connected to a scuba tank/regulator at the moment of egress would be the bailout solution, for shallow depths. If your going any deeper, the scuba regulator is very poor insurance. I would say, even the K-250 dives below this threshold, and should have all of the above features.

I also carry an emersion suit because the water I dive in is extremely cold. Guarded ports is a biggy, I have a couple of ports that are quite vulnerable and have had a scare already. I am defiantly addressing that.

Egress out of the sub is a different scenario and not one that I like to entertain.

Also in the situation where you flood the sub to escape, you need air on tap for the final pressure equalisation.

The oxygen is delivered by a standard cylinder/regulator/flow meter, setup to deliver at the standard rate that will be consumed, this can be adjusted since there are variables like; the number of occupants, etc.. an O2 high/low alarm helps ensure the range is maintained. This O2 is delivered to the cabin, through the CO2 scrubber since it has a fan and will help disperse the O2 into the cabin. It is also connected to the scrubber to ensure O2 and scrubbed/filtered air is delivered directly to full face respirators (and not the fire) for consumption in an emergency situation. In this situation, the occupant's lungs do the work, not a fan, since electrical power may not be available. The scrubber is designed around using "Pre-Pak" carbon dioxide absorbent containers that can be quickly changed out, they eliminate the possibility of dusting the cabin with absorbent. It has two pwm fans (one is a backup), and an air filter. Combating a fire, may be best done with a Super Soaker filled with deionized water. This system is compact, fairly simply and very reliable. I would like to offer it as a purchasable kit someday to those wanting a complete system. Yes, one of these days I should add my stuff to the photos section of the PSUBS page.

The sub came to the USA in the 90,s and has been sitting since. The Sever is rated for over 6,000 feet and is about 36 feet long. I tried to buy it but the owner did not get back to me. I am sure it can be bought, they did not say NO. My first plan was to haul it home but it is just to much trouble to move that far. My next idea was to cut the front head off and the rear head with CT and shit that home and weld back together. You could have a very deep diving sub in the 10 ton range. I am happy to pass on any info if anyone wants it. I would do it but it is just to money for me to spend.

In-Reply-To: References: Message-ID: I think that's exactly what it is. I spent several years trying to get a chamber on the big Island as anyone that gets bent has to fly in a special aircraft low level to Oahu to receive treatment and by the time they get re pressed, a lot can happen. The tab for the flight one way was around $20,000 I've been told. I looked at a LOT of systems and wanted a double lock to be able to get to the patient if they had a bad reaction to 02 but the majority of them were single lock. All the dive shops here loved the idea but non of them were willing to help financially with the yearly overhead even though I was willing to purchase it and ship it here so I gave up!

I just want to keep my battery banks topped up without having to rig the proper charger up every weekend. I was going to try and do it with a solar system, but investigating, it looks like it will be too expensive for anything that's going to have enough power. So, im going back to having it plugged in. There are plenty of options, just wondered if anyone has any experience with them? I need a fully automatic 24v trickle charger that's not too expensive. Was thinking of something like this. http://www.ebay.co.uk/itm/Smart-4A-24V-Sealed-Lead-Acid-Battery-Charger-Intelligent-Trickle-AGM-GEL-SLA-/161572510925?pt=LH_DefaultDomain_3&hash=item259e78dccd or even this little thing. http://www.ebay.co.uk/itm/Smart-300mA-24V-Sealed-Lead-Acid-Battery-Charger-Intelligent-Automatic-Trickle-/161550813587?pt=LH_DefaultDomain_3&hash=item259d2dc993 Just a thought, thanks James -------------- next part -------------- An HTML attachment was scrubbed...

I made a cutter for my cue ball for 1/8 with a 5/8 bore. I may be wrong but it seems to me that a bigger cross section o ring will have more surface contact on the rod, making it seal better especially if all is not perfect. Can you not buy an appropriate cutter? I usually make them by grinding a regular gutter down. Maybe a pro machinist could comment.

The groove cutters I've looked at did not go up that high considering the shank has to go in the 1/2" hole. I'm sure it could be done, and your right about the surface area , but when you consider the tolerance of the shaft to the bore we're only talking about .005 difference or so.

I'm sure it could be done, and your right about the surface area , but when you consider the tolerance of the shaft to the bore we're only talking about .005 difference or so.

I will need probably close to a dozen of them. I'm making them all to accept a 1/2" stainless shaft, and I will be using 1/16" O rings. I don't see any need to use thicker diameter O rings , since the deeper O ring grooves can be a bit more problematic. By the time my welder finishes all the remaining critical welds I should have my thru hulls done. Also working on my forward hard ballast tank, approx. 18" in dia X 5' long .

You have a bigger tolerance then to wear and machining tolerances etc. Sorry I don't know what the pressures or diameters are that you are dealing with. One of the things that we do is use FS-3452 Fluorosilicon grease which has a great life but compatibility may be an issue to check. The other thing is to use the oxygen grease which is as slippery as.

The larger o ring will help when the rod is compromised etc. I think I went .119 or so, the chart will tell you the minimum and I went the min because the rod is very low rpm and well lubricated.

I think for rotating rods though you're suppose to have the O ring in the bore, that way the O ring will not tend to turn in the groove. If you have it on the rod there is more surface area in contact with the O ring with respect to the rod rather than the Bore, there by inducing the O ring to turn in the groove. I think the only issue is that I want to use a 1/2" rod in many different places, as it turns out if I had a rod that was .491 I would be right on the money using my 2-014 O ring and that would be good for 800 psi according to the Parker rotary O-ring seal specs. But I really don't feel like machining all my 1/2" rods down .009" . I can strike a happy medium with the my easy to acquire 1/2" rod by tweaking the tolerances with-in acceptable limits.

A bit of extra security on the seal. I cocked up making that seal as per the plans so did mine a different way. However, I was never keen on the original design anyway. I believe George had at least one battery pod flood at some point. You could even maybe make your own version of that coupling. A ring of rubber say 2" wide covering the joint with a suitably made stainless ring cramped over it. Would be easy to make. You could even maybe use a piece of rubber cut from an old inner tube and stretched over. Not very sophisticated but would probably work and cheaper? Also there wouldn't be anywhere for water to collect and there would be no metal contact to rub your paint off. Just a thought.

What specification should I ask for? (Europe) I asked for EN10204 with 3.1 Sertificate (Not 100% sure of this, but this is what I got when I ordered the endcaps from another company. 3.2 Sertificate was a bit too expensive) Told them I had no special requirements for the plates and needed no edge preperation. *They replied*: "this is not the normal enquiry type, but we will not ask any longer" (?) And said the plates was going to be EN10028-3 with certificate 3.2. I want to keep the cost down, but should I ask that they grit blast the shell after rolling? Also I didn`t ask for bevel on the edges. Again to keep cost down. But maybe I should, to spare me the extra work?

The more important questions are bolt/nut material, thread engagement and torque. The argument for sticking with coarse threads would be that you reduce the chance for cross threading the wrong bolt during assembly, since coarse threads are predominately used.

Not knowing what to specify on the order. I believe the EN number is a certificate of the material quality. Mine was done to EN10204.3.1.B but i never specified it. I just asked for the material type. So just ask for your dimensions of shell, material, percentage of round, bevel, weld. Example. Shell. P355 Steel. 10mm Thick. OD 1000mm x 2000mm length. Shell to be within +\- 3mm on diameter. Welded seam. 35 degree external bevel with 2mm nose. Something like that should do it. They will send you a quote and should tell you what material grade it what code they will be working to. Make sure you specify clearly the tolerance of roundness you want and say your not paying for it if its not right. They will probably need to re-roll the cylinder. Ideally go to the factory with a wooden template and measure the cylinder before you accept it. Get the bevel put on, it will save you pain. But. don't bother with grit blasting, you need to paint it straight away after that or it will start to oxidise again. By the time you've finished your hull, it will be all rusty again. Grit blast when you've finished working on the hull. Someone else may have some other suggestions. Comments. Hope this helps. Kind Regards James On 21 March 2015 at 22:30, Andr?

Ie. when the steel gets smelted and poured into a block (or whatever) at the mill, that particular batch gets analysed for exact percentages of all elements, and all parts poured from that batch are given the "heat number" of the batch. Since the certificate is meant to trace back to the original steel mill, it's often called a "Mill Certificate". Each time the steel goes through a process (ie. rolling into sheet, the sheet formed into pipe or endcaps) there is a chance the traceabilty to the original analysed composition could be lost, if the material gets mixed up - and there are varying levels of quality control that make sure of this, and these are reflected in different types of material certificates. The EN 3.1 cert is pretty high end (ie. good enough for the SS304/316 cryogenic liquid ethane pressure vessels I'm currently involved with at work) and typical for most industrial applications at least. I've not come across requirements for 3.2 (which is even more stringent), and we frequently work with lesser requirements than 3.1. Here's a good explanation of the difference: http://www.classicfilters.com/blog/materialcertificates/ Tracing the material back to the mill is supposed to be important in case there is a failure in another part in the same batch, so it can prevent other failures. I've always thought the whole certificate/traceability thing was just a PITA and that so long as you get steel or parts from reputable suppliers who's QC practises you trust, then that's just as effective. Especially when you're building a big system with hundreds of welded parts.

I have an aluminum bow dome retaining ring bolted to an aluminum seat. I used aluminum screws, to reduce galvanic pair issues. And then I broke off one of the screws by pure clumsiness. I will have to drill this out, as there's virtually no stub, and will probably end up with one screw larger than the rest if I need to re-tap. But my question is... would you guys recommend using aluminum screws in this scenario? I am not really concerned about their holding power, there's a large quantity of screws involved.

I am new to browsing this mailing list, right now as a matter of interest, not planning on building anything.. As a diver and also as a professional metal worker I am intrigued by the K-350 and also by the propane tank sub. As a seasoned journeyman machinist I can say with confidence that it is course threads which are meant to be used in aluminum - primarily because of it's lower strength in shear and it's higher ductility which effects the cross-sectional strength of the thread at the pitch line. As a matter of practice in my trade fine threads are never used in aluminum due to the ease of stripping them. That said, I look forward to learning more from this group and am very impressed with the work displayed.

I am new to browsing this mailing list, right now as a matter of interest, not planning on building anything.. As a diver and also as a professional metal worker I am intrigued by the K-350 and also by the propane tank sub. As a seasoned journeyman machinist I can say with confidence that it is course threads which are meant to be used in aluminum - primarily because of it's lower strength in shear and it's higher ductility which effects the cross-sectional strength of the thread at the pitch line. As a matter of practice in my trade fine threads are never used in aluminum due to the ease of stripping them. That said, I look forward to learning more from this group and am very impressed with the work displayed.

Ie. when the steel gets smelted and poured into a block (or whatever) at the mill, that particular batch gets analysed for exact percentages of all elements, and all parts poured from that batch are given the "heat number" of the batch. Since the certificate is meant to trace back to the original steel mill, it's often called a "Mill Certificate". Each time the steel goes through a process (ie. rolling into sheet, the sheet formed into pipe or endcaps) there is a chance the traceabilty to the original analysed composition could be lost, if the material gets mixed up - and there are varying levels of quality control that make sure of this, and these are reflected in different types of material certificates. The EN 3.1 cert is pretty high end (ie. good enough for the SS304/316 cryogenic liquid ethane pressure vessels I'm currently involved with at work) and typical for most industrial applications at least. I've not come across requirements for 3.2 (which is even more stringent), and we frequently work with lesser requirements than 3.1. Here's a good explanation of the difference: http://www.classicfilters.com/blog/materialcertificates/ Tracing the material back to the mill is supposed to be important in case there is a failure in another part in the same batch, so it can prevent other failures. I've always thought the whole certificate/traceability thing was just a PITA and that so long as you get steel or parts from reputable suppliers who's QC practises you trust, then that's just as effective.

Not knowing what to specify on the order. I believe the EN number is a certificate of the material quality. Mine was done to EN10204.3.1.B but i never specified it. I just asked for the material type. So just ask for your dimensions of shell, material, percentage of round, bevel, weld. Example. Shell. P355 Steel. 10mm Thick. OD 1000mm x 2000mm length. Shell to be within +\- 3mm on diameter. Welded seam. 35 degree external bevel with 2mm nose. Something like that should do it. They will send you a quote and should tell you what material grade it what code they will be working to. Make sure you specify clearly the tolerance of roundness you want and say your not paying for it if its not right. They will probably need to re-roll the cylinder. Ideally go to the factory with a wooden template and measure the cylinder before you accept it. Get the bevel put on, it will save you pain. But. don't bother with grit blasting, you need to paint it straight away after that or it will start to oxidise again. By the time you've finished your hull, it will be all rusty again.

I am new to browsing this mailing list, right now as a matter of interest, not planning on building anything.. As a diver and also as a professional metal worker I am intrigued by the K-350 and also by the propane tank sub. As a seasoned journeyman machinist I can say with confidence that it is course threads which are meant to be used in aluminum - primarily because of it's lower strength in shear and it's higher ductility which effects the cross-sectional strength of the thread at the pitch line. As a matter of practice in my trade fine threads are never used in aluminum due to the ease of stripping them. That said, I look forward to learning more from this group and am very impressed with the work displayed.

Regards James On 23 March 2015 at 12:18, Stephen Fordyce via Personal_Submersibles wrote: Hi guys, The material certificate thing is all about quality control and traceability of exactly what is the composition of the elements in it. Ie. when the steel gets smelted and poured into a block (or whatever) at the mill, that particular batch gets analysed for exact percentages of all elements, and all parts poured from that batch are given the "heat number" of the batch. Since the certificate is meant to trace back to the original steel mill, it's often called a "Mill Certificate". Each time the steel goes through a process (ie. rolling into sheet, the sheet formed into pipe or endcaps) there is a chance the traceabilty to the original analysed composition could be lost, if the material gets mixed up - and there are varying levels of quality control that make sure of this, and these are reflected in different types of material certificates. The EN 3.1 cert is pretty high end (ie. good enough for the SS304/316 cryogenic liquid ethane pressure vessels I'm currently involved with at work) and typical for most industrial applications at least. I've not come across requirements for 3.2 (which is even more stringent), and we frequently work with lesser requirements than 3.1. Here's a good explanation of the difference: http://www.classicfilters.com/blog/materialcertificates/ Tracing the material back to the mill is supposed to be important in case there is a failure in another part in the same batch, so it can prevent other failures. I've always thought the whole certificate/traceability thing was just a PITA and that so long as you get steel or parts from reputable suppliers who's QC practises you trust, then that's just as effective. Especially when you're building a big system with hundreds of welded parts.

Its being scrapped as its no longer in test, but is in really good consition. What do people think? Is this something I could possibly investigate, or is it a complete waste of time? Obviously the shell thickness\material\end caps etc would all have to be investigate, but the fact that its been used as a pressure vessel for internal storage. Would this cause issues?

Typically, chambers are built without reinforcing ribs. The engineers used wall thickness to compensate, as weight is/was not an issue. Add ribs for stability and you will probably get quite a depth rating. I would say it is definitely worth looking into.

Hi All, I am thinking about my next sub. Wont be for a while yet so its just in ideas stage. However, I have the opportunity to possibly get an old hyperbaric chamber. Its about the right size I want for my new boat. Obviously there is a lot of work to do to make it a sub and im not even sure of the thickness of the shell. Its being scrapped as its no longer in test, but is in really good consition. What do people think? Is this something I could possibly investigate, or is it a complete waste of time? Obviously the shell thickness\material\end caps etc would all have to be investigate, but the fact that its been used as a pressure vessel for internal storage. Would this cause issues?

That will give you the shell thickness etc. Nice thing about a chamber is, it will be built very nice and will be clean. It will fun to figure out what you can do. Maybe the hatch can be reversed?

In-Reply-To: References: Message-ID: Yeh, I forgot to mention that the viewports are also designed to seal from the inside so that would have to be changed. A 2m OD is a pretty large deco system if that is what it is. Couple things to think about, being a double lock system, there is the weight of the extra dish and hatch inside plus having such a large OD, you would need a heck of a lot of ballast to counter that positive bouyancy. Also need to have someone on the list re calc the numbers to come up with a proper frame size and distance apart.

Yeh, I forgot to mention that the viewports are also designed to seal from the inside so that would have to be changed. A 2m OD is a pretty large deco system if that is what it is. Couple things to think about, being a double lock system, there is the weight of the extra dish and hatch inside plus having such a large OD, you would need a heck of a lot of ballast to counter that positive bouyancy. Also need to have someone on the list re calc the numbers to come up with a proper frame size and distance apart. Good luck Rick On Thu, Mar 26, 2015 at 7:31 AM, James Frankland via Personal_Submersibles wrote: I've been in this one (as a test, not for treatment). Its about 2m OD x maybe 4m. There is a lock out chamber. Hatches open inwards of course and all the viewports are back to front! I've found out they are going to get it cut up in situ. Not sure if they will even let me have it yet, but even if they do, ive got to see first if its suitable, and then if I can get it moved for less than the cost of a new shell. We'll see. I'm investigating.

You would also need to add internal or external frames and if you chose to go internal, you would have to install them in two or more pieces as the chambers have the dished ends on them and then a smallish entry hatch to contend with plus any system that I have been in, the doors are designed to seal from interanl pressure. Just some things to ponder. Rick On Thu, Mar 26, 2015 at 1:52 AM, James Frankland via Personal_Submersibles wrote: Hi All, I am thinking about my next sub. Wont be for a while yet so its just in ideas stage. However, I have the opportunity to possibly get an old hyperbaric chamber. Its about the right size I want for my new boat. Obviously there is a lot of work to do to make it a sub and im not even sure of the thickness of the shell. Its being scrapped as its no longer in test, but is in really good consition. What do people think? Is this something I could possibly investigate, or is it a complete waste of time? Obviously the shell thickness\material\end caps etc would all have to be investigate, but the fact that its been used as a pressure vessel for internal storage. Would this cause issues? Just wanted to see what people think before I investigate.

Bridgelux makes a 10,000 lumen array that is 2" in diameter. It runs up to 38 volts. I ordered it to try it. I'll post what I find. Thanks, Scott Sent from my U.S. Cellular?
