Used to shoot beer cans full of gravel but could never find them afterwards.
Ha! That actually makes it even better! Very cool!Yeah, I built that years ago. Barrel is a chunk of high presser gas vessel with 1 1/2 inch thick walls. Welded a piece of rebar around the muzzle and used fiberglass cloth/resin to make the taper. Welded barrel lugs, rear plate and the knob on the rear is a door knob. Used to mix up my own flashpowder but pretty much lack the guts to do that anymore.
Made a golf ball cannon about 15 years ago but blew it up and decided it was not a good play thing after all. Apparently you can't just double the charge and stuff 2 balls in her! :;:smokin;:;badidea
We shoot a potato gun now and then, haven't blown anything or anybody up yet thankfully. Amazing how far those som bitches will fly if you can get the hairspray concentration correct.
Ever Tried Starting fluid in it??
