i just was bored out of my mind so i decided to thow together a few things and make a c02 gun. i found an old c02 bike pump some duct tape, vinyl tubing, and copper pipe threw it all together and presto!!!
i thought of using a piece of 8 1/2" PVC 4 the base and two pieces of PVC big enough to hold those green balls
i would pressurize the base and attatch two hose handles to the barrels
then using a long piece of PVC 4 the drop feed system
