I have always wanted to see a machinist make a semi-auto 50x hybrid bowling ball shooter that is handheld Wink .

You might want to consider something like http://www.swanstrom.net/petes/shoot/autobb.htm

Convert the block to say aluminum, turn a nice efficient piston ...

One question How do you get the bowling ball to stick to the magnet

Had to say it as the two above posts were consecutive.
Nice BBMG by the way. I like it.
