Snog Valve Wars

Tom Rose · 7th October 2007, 23:34

I have purchased quite a bit of silicone and urethane castable materials from

JGreer.com - Epoxy Resin, Urethane Foam, Silicone Mold Making Rubber, Carbon Fiber

A really nice guy who will talk you through things.

Ive spent several thousand dollars with him over the last year....

Don't ask...go to DEMA....

Well after pondering for a bit I came up with a concept. A normal rubber mouthpiece would be used and I may even be able to adapt one of my current DSV with ease. I'm not too keen on the BCD hose but more along the lines of the FIENO. Anyone ever get to gut one of those little gems? Well I did and I'm going for the micro pnumatic lines to feed to the snog valve. A little tinkering to fit in a lever to open a schrader valve. This could be an under $20.00 project.

Hi,

If you can make a pattern for the mouthpiece, it's not so difficult to take a mould from it either in silicon or urethane.
You might even get a way with a single part mould with a cut line to allow removal of the part.
The more tricky part is finding a suitable silicon(or perhaps urethane) to mould the mouthpiece from.
Teeth are very sharp, and many of the typically available two part silicon rubbers would not last very long IMHO.....and there is always the worry unmixed catalyst...tin or plantinum
I havent used the type of beautiful silicon that masks etc are made from...some are three part mixes......but I have moulded a lot of different things and just about anything is possible

This is why I'm not all that excited about attempting to mold a special rubber mouthpiece. There are a few mini pnumatic line options out there. I've got to order some stuff in but when I get a rig set up for testing I'll post the images.

Would love to get my hands on a FIENO (or just the DSV). Remember some pictures of all those fairly intricate pneumatic lines, does anyone have a link?

So I allowed myself to think about modifying the DSV to get something. Still feel the standardized fittings like a BCD or CEJN would be nice for flexibility and short setup time.

So a simple first draft (not ready for diving). The idea is that the knob that is used to operate the DSV can function both as a knob and SNOG-port. The elbow is swiveled so the BCD-hose can move when the DSV is operated and the stick is just long enough to not interfere with the closing/opening of the DSV. I can touch it just fine with my tounge. The outside parts on the pictures can be made at least ~5 mm lower in profile.

Thinking about it this sort of mod could be even easier on a BOV-DSV...(My Divematics is probably very scared now)

Wow.. that was fast. I like the idea so far. With the right parts it could be a very stout way to add the gas of ones choice. Can you machine parts or would you have to hire that out?

Yes thats a problem for me. Have various friends that can machine things for me now and then, combined with buying custom parts (like from Välkommen till Divex! or Tauchen - Cave, Nitrox, Rebreather Ausbildung, Tec Ausrüstung, Reisen)

Will have to work on finding best tap/die/hexnut/seal solution for the RAY-DSV-SNOG before it can be dived (don't want the thing to break easily).

PS
Found the FIENO thread I was thinking about:

Thats an excelent idea JAAP, but do you really reach the stick with your tounge with out having to extend the stick so you still can shut teh DSV off?

Perhaps my fysionomy is abnormal...but for me it seems to work just fine when the stick is like in the pictures. Infact the stick can even be made to extend a few more mm towards the diver before it interferes with the closing. An on other DSV that rotates along an axis extending from the mouth (like on many BOVs or DSV's made from a ball valve) the stick can even be made to extend as far as ju like.

haha the new Gene Simmons is here :P Tried a litte with my FGT dsv and there was no way I could reach it. it's a RAY mouthpiece you have huh? Perhaps they are smaller...
