All I have to do is paint it. the gray patches behind the barrel are epoxy that i put on each side of the gun because the barrel was wider than the wood. the gray on the barrel is also epoxy i formed it by wrapping the barrel in saran wrap(did i spell that right?). then i squeezed the epoxy into the gap between the barrel and the wood. the epoxy bonded to the wood and the saran wrap and not the barrel then i went back with sander, file, and sand paper to make it look nice. I think the next one I will make will have a much shorter barrel and no stock maybe 1' to 9" in length.
I might creat a Potato cannon barrel that i can switch out. all i would need was a cap on the breach that had the igniter on it.
Much better pictures!
