The upper portion of the pressure hull that has the viewports is 36" x 0.25 A516-70 pressure vessel steel. The design depth is 500 ft. I like the optics of flat viewports so I have one 24" diameter x 4" thick acrylic viewport and three smaller 12" viewports. I ran the calcs using the PVHO flat viewport calculator that Jon Wallace implemented at the PSubs site. I have access to abrasive water jet so I was thinking of jetting these out of off the shelf acrylic and then having a machine shop dress the edges and cut the chamfers. I would need to get the viewports annealed after final machining. I am hoping I can talk Gregg Cotrell into doing this for me as he is Dr. Acrylic. PVHO has detailed info on what the viewport housing seat needs to look like. So to me, I don't see any reason Vance you could not use large flat viewport on the bow. You just have to do the PVHO calcs on the thickness and housing dimensions for your design depth. You would need to design the housing to smoothly transition the stresses to the forward head and run an FEA to confirm stresses in the viewport and housing. I don't know what size you were thinking about or the design depth but it would need be thick.

I would defer to Gregg Cotrell for a position on this. My guess is that if you have to do any machining this causes heat and induced stress. In my case, I would need to dress the edges after abrasive jetting so, my guess is that I would need to get it annealed. I guess the question is for your viewport even though it is cast, is further machining required? If so this would induce stress, if not you probably don't need to anneal it but you should check with Greg.

I am not sure if I understood that correctly. My understanding is that R-Cast Acrylic does not need further annealing. Again I might have that wrong, do you know.

Message-ID: Good morning, Roberto, One of the very best ways to learn about all of the systems and aspects of small subs would be to buy the book Manned Submersibles by frank Busby. Almost all of us in PSubs have this book. It's available on Amazon. Be sure to get the hard-cover edition with the purple cover. There is a soft-cover reprint, but it does not have any of the pictures and charts in it. Here's the link: _http://www.amazon.com/s/ref=nb_sb_ss_i_3_6?url=search-alias%3Dstripbooks&field-keywords=manned%20submersibles&sprefix=manned%2Cstripbooks %2C224_ (http://www.amazon.com/s/ref=nb_sb_ss_i_3_6?url=search-alias=stripbooks&field-keywords=manned%20submersibles&sprefix=manned,stripbooks,224) Also, could you introduce yourself to the group and tell us where you live, tell us about your background and experience, how you plan to use a sub, are you a scuba diver, etc. It's possible that one of our members lives near you.

That would give the scrubber something to work on from the first breath, whereas if you were sucking air through the scrubber, it wouldn't have anything much to scrub until the entire cabin CO2 concentration rose. Also, exhaling through the scrubber I like the idea that I wouldn't be breathing in any Sofnolime dust.

The project sounds a lot like the old Galeazzi observation chamber. Here is a photo: http://www.divingmuseum.org/wp-content/gallery/exhibits/picture-019.jpg The one thing I would point out is that your visibility of the bottom, through the dome, will be very limited. A K-250 style dome has good optics looking through the apex (i.e. straight up at the surface) but really bad visibility when looking sideways out of the edge. I suspect it is because these are blown domes and therefore not of constant thickness. But the bottom line is horizontal visibility through a K250 dome is terrible and if you can, I would urge you to consider flat viewports instead. If going to all the trouble of building this, it would seem you are only a few steps away from making it into a complete K250.

Also the hydrocarbons from the gas migrate into the metal and interfere with the integrity of new welds. A few people have made very shallow subs from LPG used tanks, but you wouldn't really gain much cost advantage, and you would sacrifice capability and safety. You would also run into other problems installing the hull penetrations. Many of us initially thought of using an old propane tank, but quickly discarded the idea. On the Psubs site if you will go to PSUBS Community, then Projects & Photos, you will be able to look at the journals of the building process of a number of subs. These two links are excellent: http://www.psubs.org/projects/1245611411/kw350trustworthy/ http://www.guernseysubmarine.com/ You will learn a lot from both of them. The process of building a sub from an existing design takes a long time. Creating a new design takes much longer. Best wishes, Jim T. In a message dated 11/12/2014 2:52:30 P.M.

Good Morning, first i am not an electronics master, was working on the co2 scrubers , then? my imagination again move ahead of my hands and make me thik that the scruber must be inteligent,? based on the parameters cabin pressure,CO2 , O2 concentration and temperature,? i think that will be helpfull a device for monitor this conditions, found a programable board with the optional? sensors, the UNO ( 4 dlls on ebay ) the barometric pressure sensor ( 2 dlls on ebay )? the carbon monoxide sensor ( 4 dlls) , tilt sensors (1.75 usd) and many other sensors with this info, this boar will check cabin pressure and co2 %, the boar can activate a relay to let oxigen enter and keep a safe enviroment also the tilt sensors can help me to control position in low visibility conditions, may be will need 3 boards and several sensors that will let me have an auxiliar control system Another system that i need develop? or know if can be develop or find is a neutral bouyancy , based in flow of water on the vertical axle, this black box ( because i dont know what will have inside )? will control valves on the variable ballast system just my ideas, if this is for sale some were ,please tell me to consider with the arduino a complet system looks to be below 100 usd as will be common sensors ans actuators ( relays ) i draw a system using just relays and mercury switches ( the ones that stop the outboard when tilt,or on the ac thermosthats )? buw will take a big space and many meters of wire, will be a heat source , a single boar can solve this, buti need your comments, thanks _______________________________________________ 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...

Technically, seawater density is a function of both temperature and salinity (and very slight compressibility), but the user just enters an average value for density. Similarly, the shell material properties can be tweaked from the average values that are programmed in as defaults, to accommodate specific known material test values or just for increased conservatism. The calculations are assumed to be valid for any material within transition temperature limits, but no specific attempt is made to model creep in acrylic or toughness transitions in shell materials at extremely low or high temperatures. This software is just an implementation of the formulas presented in the ABS Rules. Simply put, if seawater is still liquid at your operating temperature, you're probably okay. The lack of perfect determinism at failure is why we have safety factors.

If you are interested it should bepossible to dig it up. There are pictures of it in his Psubs project page.Alan?On the R300, I have life support module I call the AMOC system (Air monitoring and Oxygen Control).? Connected to the box is a 1/4" SS tubing with Swagelok fittings connected to a O2 supply from an external 2200 psig O2 bottle. I fill this with welding O2 with a whip.? ? In the AMOC module is a medical pressure reducing regulator (Hudson model 2000).? This regulator? reduces the pressure to around 5 psig.? The?pressure downstream of?the regulator is adjustable with a maximum rate of 15 SLPM.? The porting on this regulator?is two 1/4" NPT HP ports and one LP port.??Downstream of this regulator, I have installed an O2 thermal mass meter/ controller from Porter.? The model number is 201-FSVP.? This controller can be set from 0-10 SLPM via an 0-5V analog input signal.?Max pressure on the O2 controller is 25 psig.? This O2 controller also sends out at 0-5V analog output signal?of the O2 SLPM?flow rate. Both these items were purchased on Ebay at a fraction of list.????I have been very happy with the performance of these units.? By measuring the O2 and CO2 percentages in the cabin, I have a PLC that opens and closes this controller to keep the cabin O2 % between 19-22%.? ABS regulations requires that the O2 be held with in 18-24%.? The advantage of this system is that it automatically accounts for different metabolic consumptions rates for O2.? In?the AMOC unit, I have a Swagelok needle valve in a bypass around this controller so that if both main and back up power?are lost, the pilot can manually adjust the O2 rate into the boat. The second part to controlling the atmosphere in the cabin?is scrubbing the CO2.? I initially used a axial flow filter with SodaSorb HP.? I found that the axial flow filter did not work very well with CO2 in the cabin ranging from 0-7000 ppm.? Part of the problem was the axial filter arrangement and part of the problem was the blower was not strong enough.? At the 2012 PSUB convention in Vancouver, Alec Symth brought the scrubber?he?was using on Snoopy as a show and tell.? His scrubber is an OTS radial filter that is used to?clean air.? In 2013, I switch to this type of scrubber/filer again with SodaSorb HB and the scrubber has worked much better.? It consistently keeps the CO2 level below 2000 ppm with most of the time it being 1000-1500 ppm.? ABS rules require that you keep O2 concentration below 5000 ppm.? Part of the reason that is works better is the radial design which minimizes the pressure drop through the Sodasorb and part is that I have switched to a stronger blower.

Technically, seawater density is a function of both temperature and salinity (and very slight compressibility), but the user just enters an average value for density. Similarly, the shell material properties can be tweaked from the average values that are programmed in as defaults, to accommodate specific known material test values or just for increased conservatism. The calculations are assumed to be valid for any material within transition temperature limits, but no specific attempt is made to model creep in acrylic or toughness transitions in shell materials at extremely low or high temperatures. This software is just an implementation of the formulas presented in the ABS Rules. Simply put, if seawater is still liquid at your operating temperature, you're probably okay.

There is a 155 seal on ebay right now sitting at 80 dollars with 6hr to go. The seal is a number 9 that means 1 1/8 shaft size. That seal is 1,700 dollars in Vancouver Canada, well worth it to upsize the shaft to fit the seal.

My submarine Had a Chesterton 891-8 mechanical seal and was ABS certified to 1,000 feet. Go with proven parts. I thought the K250 has a rear motor pod with a spring loaded mechanical seal. You don't need a pressure tank. Build the system so you can cap the propeller shaft tube and pressurise it. If you look at my project page, Gamma Restoration, you can see how I pressure test the seal assembly. You can also see the 155 seal, I have since upgraded to a magnetic coupler.

The composites also introduce new modes of failure, such as interlayer delamination. That said, they can and have been used as pressure hull materials, but you generally will need to custom model the behavior with regard to your hull geometry. In a typical composite layup, the average material properties are approximately equal to the average material properties of the matrix and reinforcement in proportion to their respective volume fractions, but failure modes are still dictated by the weaker or more brittle material. Performance is also dependent on layer thickness and principal fiber orientation in each layer. Fiber reinforced composites will tend to fail catastrophically in a shear mode, versus yielding inelastically as with steel, so you need to be very confident in your strength analysis to go this route.

Even as a practicing mechanical engineer, it would take me weeks to do a stress analysis on the hull. The only safe way to determine the strength of the hull is a destructive test where you take it failure. After you complete the test, you lay up a second hull. If you lay up the mat in a different orientation, the strength of the hull would be different. This is why most builders use steel that has a very predictable and linear stress strain relationship.

I didn't buy this, a relative who is a miner gave it to me. Must have got lost in the Colliery changing room... Anyway, it does 4 gasses, Oxygen, Carbon Monoxide, Methane and Hydrogen. Seems very good. If bought new, you can get one that does co2 instead of co. Not sure the other gases are of any concern. Maybe hydrogen i suppose from the batteries. The problem with this one is that it has a sampling fan inside, so its constantly sucking in air through that pipe at the top. Its not a major drama but it makes it a bit noisy. This would be the best one if it did co2 instead, but i wouldn't buy one, too expensive. The orange thing is my CO2 monitor. Kind Regards James ?

When looking for a sensor for 1 ATM sub use, keep in mind the necessary measurement range - you don't need a sensor capable of high PPO2 such as those used in rebreathers when the maximum possible PPO2 in a 1 ATM space is 1 ATM.

The first two came as a pair in an eBay auction, which was ideal because that way I had a spare. I sure needed it, because the first one lasted 15 minutes in the heat and humidity of a Florida dive. They seemed like ideal units; brand name, back-lit display, high and low visual and audible alarms. The second lasted a bit longer, maybe a season. Then I cobbled together a working one by combining parts from the two and got one more season out of that. It was instructive taking these things apart. After just a few dives the printed circuit boards looked like the terminals on an old car battery, all covered in whitish gunk, and its not like I dropped them over the side. My take-away was to avoid instruments that are intended for a hospital. Go instead for something intended for the field (sealed, clip-on, small enough to go in your pocket, etc.) The hospital units work perfectly in the garage but die very soon after you start using them on actual dives. My current one you can find on eBay by searching "SPD201". It has the benefit of being really cheap. It is not as ruggedly encased as more expensive field units, but it has managed to survive several seasons without turning into a battery terminal, so I'd rate the quality as "not the best but good enough". There are two things I'd change about it, but they're both minor. First, it has two alarms but they are both low alarms and for our application it would be better to have one high and one low alarm. Second, the backlight comes on when you press a button but turns itself off after a while to conserve the battery - I'd rather it stayed on until switched off again.

It also does H2 but not to scale Registers as CO. i.e. it goes off with lead acid battery charging. Was not cheap and needs ?Calibration? every year and tells you so. We have accessed the internals via computer to download and use its data sourcing to control the Oxy input solenoid. Crowcon say it cant be done but we have done it anyway.

A cue ball arm can be made very easily with a 1 1/4 ss ball valve and a 1 1/8 dia cue ball. I removed the ss ball from the valve, just to check it out and found the ball is .004 in smaller than the cue ball. I am going to assemble the valve with the cue ball in it and pressure test it. If it works, I will machine the valve ends so the cue ball arm has maximum range of motion. To build a duplicate cue ball arm like Gamma has requires some extremely technical machining. When I removed the insert that carries the cue ball, from the hull, I found it was damaged and causes the cue ball to drag causing damage to the ball. Since I do not have the skills and equipment to machine that part with the radius in it, I will try the valve idea.

Some time ago I suggested using a valve & looked at items such as this http://www.stoneleigh-eng.com/duplex_ball_valve.html that could be pulled apart easily & were thin sectioned to enable greater angle of movement. My idea at the time was to use the existing ball but turn it, & drill out it's stem hole to fit the cue. But this would be great if the cue ball fits. There are a myriad of valves out there. If you found one that could be easily attached to the hull & just bolted together with the machined cue ball in it, that would make it easier to emulate. Have a look at this Wiki article. Pool balls / billiard balls differ in size & you may find a match up between a ball & a valve. http://en.m.wikipedia.org/wiki/Billiard_ball Alan Sent from my iPad > On 28/11/2014, at 2:35 am, hank pronk via Personal_Submersibles wrote: > e > I have made a big discovery.

The arm will have quite good range, admittedly not as much as the original. I put the assembly on the sub and the arm will travel through its full range no problem.? I think the slight reduction in range is well worth it.? This system is very cheap and easy to put together, also the original has a single o-ring seal at the equator of the cue ball.? The valve has two seals.

Brass is likely to corrode faster than 316 SS if it is not looked after. The harder the better of course but if it is kept greased then you won't have a problem. Forget the seal having to be curved for the ball. We use 45 degree seats at 6000 psi. There is less torque required on a 45 degree seat than a fully shaped one and the sealing is better. We allow about 3 to 4 thou of crush from finger tight to fully torqued bolts. Because you are only doing low pressure you can get more angle with the seat contact to give you a greater movement. As I said before the secret is in the grease for ease. Do you have an oxygen grease? White stuff. Will reduce the friction by 60%.

Still want to hear from Lance. There is a lot of art as well as science in the building of these things. Generally these things have all been visited before by someone. Once we understand all the issues then we can look at improving it or not. As I said this is a fascinating project. I saw the video and the ease that the operator was picking up objects on the move some time ago and it was simple and effective. Anyway What is the diameter of the internal rod and the OD of the tube you are using? I am thinking of a way of pressure compensating it.

Very intesting. The cue ball (plastic) on a curved SS seat. Reversed SS Ball on plastic seat. No doubt there is a reason behind it all where we need a bit of history. Vance, are you listening? They will have tried a ball valve design at some stage most probably and found that the lowest friction is from the design they came up with. We usually have a torque of about 5 ft lbs but again it is for 6000 psi service. I need to have a play with this as it is quite fascinating.

Just so you know, the original cue ball sits on a ss shaped seat that matches the ball perfectly. The seal is a regular 1/8 in dia o-ring mounted at the equator of the cue ball.

Brass is likely to corrode faster than 316 SS if it is not looked after. The harder the better of course but if it is kept greased then you won't have a problem. Forget the seal having to be curved for the ball. We use 45 degree seats at 6000 psi. There is less torque required on a 45 degree seat than a fully shaped one and the sealing is better. We allow about 3 to 4 thou of crush from finger tight to fully torqued bolts. Because you are only doing low pressure you can get more angle with the seat contact to give you a greater movement. As I said before the secret is in the grease for ease. Do you have an oxygen grease? White stuff. Will reduce the friction by 60%.

I repaired the original seat for the cue ball. After Hugh said to forget about making a curved seat, I realized I could make my own seat on a 45 degree angle. I made the second half of the assembly with a home made plastic seat machined from ABS. I installed it in Gamma and it turns smooth as glass and has the original amount of range. With home made plastic seats, it is a breeze to make this because the o-ring still does the sealing. Now I just need the plans and my new cue ball to finish the arm. Vance, I was thinking about mounting an air cylinder horizontal inside the sub to pull on the block and tackle cable. The deeper I go the more air pressure I add, it will be like an adjustable spring.

It could possibly dissolve the insulation on the motor windings & destroy other plastics in the motor. Probably similar to WD40. Even though people use it successfully there have been reports of plastics becoming brittle. I experimented with WD40, soaking all sorts of plastics in it.

When I opened up a Chinese trolling motor I bought, I found the thrust bearing sitting in a plastic housing. This would have possibly lasted 5 minutes in something like WD40. The low viscosity silicone oil, I have heard is quite expensive.

If you match the cross sectional area of the rod through cue ball and the hydraulic cylinder (I guess it would be the top end, so have to subtract hydraulic rod area from piston area) it should be more or less self compensating at any depth. Fair amount of messing around to do it with maybe an oil bladder outside, through-hull, etc., but saves you having to deal with increased cabin pressure due to release of spent air from the pneumatic system, especially if you're adjusting a lot.

If you weld a ring on the way you describe with the weld in the middle, the weld shrinkage on either side of the head wall can bend the SS, leaving you with a curved SS ring. I can tell you from painful experience the amount of deflection can be amazing, we're not talking a few hundredths... In my case it was about a quarter inch.

I'd ? recommend cutting the head so it meets the ring at the ? outside corner. ? ? Best, ? ?

For some reason the wider the hatch ring the better it makes me feel, not sure why that is, maybe just more surface area to be in contact. Theoretically if your two mating pieces are perfectly flat you wouldn't even need an o ring ! Also, my welder wants me to put it in the middle.

Did you notice how narrow the land is on Gamma, it is like 3/4 inch. The hatch ring is the same, I was surprised to see that.
