Aluminum Marble Gun(updated with damage)

Unread postAuthor: locksmith » Mon Apr 23, 2007 5:40 pm

Well this is my polished aluminum breech loading marble gun.It also sports a muzzle loaded one inch copper barrel.All of the machine work was done by me.I built the tank out of 2"schedule 80 pipe with tig welded end caps.It has a toro 1"modded sprinkler valve .I also built the Trigger on the blow nozzle the stock one was tin so I machined this one out of aluminum.The barrel is polished conduit Pressed into that custom bored brass fitting and soldered.The breech was built on the lathe and has oring seals.It also has a o-ring groove on the inside to keep the marble from rolling out.I also built the one inch pellet and the one inch rocket on the lathe.It fires very well I rest the tank on my shoulder and site down the barrel.Well I hope you Like it.I have a twenty foot stick of sdr21 coming for a golf ball barrel But it didnt make it before the contest.Feel free to pm me with any questions or comments.Thes shots where at 140psi about 15 20 yards.
