From personal_submersibles at psubs.org Sat Feb 4 20:25:18 2023 From: personal_submersibles at psubs.org (Rick Patton via Personal_Submersibles) Date: Sat, 4 Feb 2023 15:25:18 -1000 Subject: [PSUBS-MAILIST] Thruster Message-ID: <657EE43B-5DF6-46B3-8C8B-9C18B213D662@gmail.com> I threaded a 1/4? piece of SS flat bar using a #8X32 tap and used it to pull the 2 wires against the inner surface of the housing to keep it from rubbing against the armature. Sealed the threads with thick pipe dope. Hopefully always an external air pressure so if air does make it past the threads, it will just be a very small stream of bubbles. Will post the results when tested. -------------- next part -------------- A non-text attachment was scrubbed...

I guess the only solution is to turn the air off while towing, but if you forgot to turn it on.....You would need a pressure activated switch that would give you a warning when there was no pressure on it. The unit I am making has the exhaust valve set at a couple of psi above the main diaphragm pressure, so wont be subject to that.Alan.

I faced the second stage to the side so that the pressure of the water while towing would be lessened on the diaphram but I don't think that would stop it just lessen it so my friend who owns several dive shops in Seattle after hearing what I wanted to do with it suggested that I use the one with the slide mechanism on it to prevent burping. The only downside is that I have to remember to have a guy retract it while he is unhooking the tow line.

If I were you I would make an extension that fits in to the exhaust port surrounds & taper it so a tube of appropriate diameter could be fitted over itat the bottom. Maybe make these extension tubes about 6" long. This will give you a little bit more backpressure on the exhaust valve to counter any pressure on the diaphragm due to towing. Then I would try it out from a boat. After this you may or may not need to shut the regulator off while towing.Alan?

Such a regulator could serve as a central source of compensation air for multiple compensated volumes, and could probably be sourced at a cost which isn't all that much greater than a SCUBA reg and the value of your time.

I am currently trying to find a supplier that can sell me the valve and lever arm on its own.I have 3d printed the body & had 40 diaphragms (minimum order quantity) made up that are rated to 80psi I also have the stainless springs for over-pressure & exhaust port pressure. I am using parts from a bcd over-pressure valve for the exhaust.The body leaked air when printing in pla at 50%, but will print in petg / carbon fibre at 100% & maybe add some resin later. Cost for parts and materials is around $60.An option I am looking at is making the body out of aluminium & using a truck tyre valve instead of the scuba valve.?Cheers Alan Sent from Yahoo Mail on Android On Thu, 9 Feb 2023 at 3:20 pm, Sean T.

I think it is a good idea to have a SW guy give a talk about their products at your next convention as it is an important topic. I finally was able to connect the wires to the brushes with spade connectors and they don't seem to be rubbing. I made a ss clip to hold the wires against the inside of the housing but ended up taking it out as the brush housing would not pass by it. I had to remove the epoxy and wires out of my last SS fitting for the aft thruster cuz I cut the wires too short so have to re pot that again. Oh well, it could be worse.
