LordTio3, you don't actually think I had any "plan's" for this project do you? Between cruising hobby shops for raw materials (brass and wood), and hardware store "grazing", for screw's finials etc, it's just a matter of pleasing the eye and keeping the proportion's "cannon-like". Before you do anything else, I suggest you make your barrel, lock it in a vise, (clamp it with wood so you don't mar the metal) and proof test it. I used 10g fff and a wad, knowing that the ball would be a loose fit and that I was going to shoot it with 5g fff. Once you know it's safe, the rest is fun.
