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

this is what is like
the tapered disks hopefully act as a one way valuve
the neopreme barrel sealing surface
the piston on top of 2" pvc (my chamber size)
a diagram of it
the friction seems pretty high but i have never done a piston befor so i dont know what to look for

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!
