Cannon template for brass casting
thingiverse
This is a template for casting a purely decorative brass cannon. It does have a barrel but it should not be used as a salute cannon or with projectiles. The construction is far to flimsy to withstand any pressure, even if cast in bronze. Salute cannons generally have a steel barrel insert. Any kind of charge in a cannon this flimsy is very dangerous. It is constructed this way only to save on material. A full #10 cruicible should suffice for this cast.
