i have to go to the hard ware store to get the rest of my supplys for my coaxail gun but i built the piston and need your input on if it will work.

it is based on btb's piston http://www.spudfiles.com/forums/viewtopic.php?t=6214&

this is what is like

the tapered disks hopefully act as a one way valuve

that wont hold a lot of pressur, the rubber should seal the piston, not form most of it

hmm looks good but i sujest a nice even cut for the circl bits of ruber, with them like that air could leak, and the piston could catch the chamber sides. lookes great tho!
