first coaxal

Unread postAuthor: homedepotpro » Wed Apr 11, 2007 12:15 am

first id like to say thank you to all the people who gave me advice along the way

the gun has a 2''x2' chamber and a 1/2''x2' barrel. the piston is made of hot glue and is actuated by a modded sprinkler valve. i havent shot it yet, im still waiting for the glue to cure. half by design and half by mistake i can change my barrels.

comments welcome

nice. what size barrels do you have for it (besides the 1/2'')? i like the fill valve in the exaust. If i could tell the future id bet that id tell you that i thought that i had imagined that you thought that i thought that i was going to tell you that you were going to blow a big hole in something with a AA batery. in other words, i like it.
