Hi everyone,
I recently bought a benchtop lathe and was working on another project where I had to bore through a long cylinder. About halfway through, I looked at it and realized I was basically building a small cannon barrel.......
I've always wanted a small cannon or mortar, but the idea of building one never occurred to me until just the other day. Eventually I would like to build a golf ball mortar, but I figured I would start with something smaller so I'm planning on a .177 caliber BB cannon. I've read a lot on here and other sites and I think I have a pretty good handle on the machine work needed and things like chamber wall thickness, etc. I do have one question though - is a separate powder chamber really needed on a .177 caliber? I'm thinking that the bore is so small already that if I have a separate chamber it will be small enough that the powder granules will hang up and not settle down into the chamber. Am I ok with just a straight bore and no chamber?
