My diafragm/piston hybrid, the valve that I had so much hope for, was a complete and utter failure when I finally tested it today. I should have just left the stinking thing assembled and sitting on the shelf and told myself that it worked beautifully. I couldn't get the stinking thing to seal across my exit pipe AT ALL. The air just ran straight through the thing like there wasn't a valve present. Dang it, this really ticks me off. I guess that is what happens when you experiment with this stuff though. I would have been OK if it had just not performed as well as I had expected, but no performance at all is just too much for me. I can't figure it out and it is going to drive me nuts. Maybe my spring wasn't strong enough, so the diafragm lifted up and let air into the exit pipe. I don't know. Anyone who wants to look and give suggestions on how to fix this piece of crap, take a look at the design at http://msdadmin.scican.net/patt/bigvalve.htm

Have a nice night everyone.

I can't seem to find any diagrams of how to make a regular old piston valve. Does anyone know of a place to find some. All I can find is one drawing on the spudzooka site and lots of pictures of partially assembled ones. I can never tell how the heck they put them together, so I am unable to build one of my own. Any help would be appreciated. Thanks.

your fill valve? it might be that the fill valve is not above the diaphram/piston (pistphragm?)

so there is no sudden surge of air pressure against the diaphragm and spring....that way it equalizes nice and evenly

MY MAJOR gun the big 1200+CI one I am ocassionally caught talking baout was a complete and utter failure.

It is a solid Plastic Piston with 2 Orings on the back end that seals on PVC pipe.
The front end seals on its front face with a 1/4 thick sheet of neoprene.

I am rebuilding it yes. But research and a new device takes time.
Keep at it.
