I found some stuff at homedepot today called epoxy putty. There is many different kinds around the store included plumbing and all purpose. I just got the all purpose. I simply took a piece of the pipe i needed it to fit in and greased it up. Then mixed up some of the putty and molded it into the pipe. It takes about 20 minutes to harden and about an hour to fully set. I cut a flat piece out of a rubber pipe cap to uses as a screw on gasket.

Don't mind him, hes on a new med(not really from what I know). Nah I dunno man, I've never seen anything about this being done to make a piston but good job on that. Is it soft enough to make a bumper also or does it actually get hard?
