I scavenged up a piece of bronze this morning. It looks big enough to make a golfball mortar. Would that be an acceptable material to use and if so how thick would the walls have to be.

Unfortunately, you don't give the diameter of your round stock. Scaling bore size to bore size (1.70/5.82), gives a wall thickness of about .275" for the thin part of a M1841 US Coehorn. That would probably be OK as long as it is limited to golf ball shot since little pressure can build up behind a golf ball. Maximum diameter is 2.527". If you have 3" stock, you could scale up but bore undersize to scale, which would give you about 1/2" walls.

Minimum diameter is 2.375 in one area and 2.500 in another area.
