Seeing tylerthetatertosser's gun reminded me of this, and that I hadn''t posted it yet. It's been sitting around in my garge since September or something.
It uses a diaphragm valve inside a 1 1/4" T, and is piloted by a blowgun. It has 3 barrels, 1/2" Sch 80 for AA batteries, 1/2" Sch 40 for other 1/2" stuff, and 1/2" SDR 13.5 for paintballs and marbles. The paintjob is weird, I know, you don't need to point it out. It's also kinda crappy, 1 coat.

I deleted old camera software, so now can resize and upload them!

Cool! Whats is the diaphragm made out of? I see that you conected the valve it self to the chamber with some type of fittings but what exactly are they? Im guessing male and female adapters but i cant quite see it clear enough to tell.

Did the diaphragm need ans equalization hole? Did you lathe down that back bushing in the first picture?

The diaphragm is 1/16" thick neoprene sheet.
The valve has 1" porting connected to the chamber (1" female coupler cut in half to make it cleaner), then a 1" steel nipple, then 1" female threads again. I wanted the valve to be removable.
Homemade diaphragms never need equalization holes, because air will always leak around the sides, no matter how tight of a fit it is. And I've already answered the last question.
