Well Im finally starting to get things off the ground and thought I would share my new site with you. I am making cannons in bronze to fire golf balls. The entire piece is wood/bronze/copper/brass/stainless so it is perfect for a marine enviroment.
I use a safety fuse for ignition and a small lighter (windproof works best). Im working on a swivel gun but dont have it finished yet. A golf ball is fired using powder yes. The ball will go 4-500 feet, when you compare this to driving a golf ball with a club going 2-300 yards it is clear that the powder puts less force on the golf ball. So realistically sing you can light it and step back it is safer than being around someone driving golf balls.
