are you making a coax or a regular T piston gun?
Well I am an idiot :D I don't know all about it. I plan on making a coax but am lost... In the link you gave me does it talk about this?

i don't believe i ever gave you a link, but I'm sure if you look around for diagrams, you will figure it out. I believe you are smart enough to do so.

Wait.. I didn't know you need another fill valve leading to the chamber. I thought that at first but then I read that the air leaks around the piston.

Click me (or else)
Thats what I read.

yeah, theres two methods, the leak method and the 2 fill up method, either one works. but you dont usually have air leak all around the piston, you just have air leak through a hole in the piston, but either way, it'll work.

Yah I like the leak method, seems cleaner. I know there should be exhaust holes but how do I make them?

I think you misunderstood or I am being an idiot agin.. When I said exhaust I meant the wholes for the air to leak into the chamber.. Wouldn't those wholes be too big and would let the air "flow" rather then leak.

Do you mean equilization holes in the piston?
if you do you dont need them unless the piston has o-rings because it wont be anywhere near airtight without orings and the air will freely fill the chamber.

I can't understand your question.. sorry but.. I am a flaming idiot.. I understand almost all of the steps on making it, just not the park of "leaking air" and o-rings..

okay just make a piston valve without orings or equalization holes and you should be fine.
