Re: T-Shirt cannon pnuematic set ups

Now that this thread has been completely hijacked by an Ego contest....


When I built my air cannon in high school, I had the help of my father who has worked in Water Treatment for about 30 years, so thankfully I was blessed with knowledge from above about pressure ratings.

I used 4 inch Galvanized Steel, and typically ran it at 135 PSI.

I was able to launch aluminum baseball bats about 250 yards with about a gallon of water in the barrel.

Enjoy some very dated pictures:
