I built an air cannon last year and it was a hit! Scared the Sh*t out of everyone that walked by. Only problem is, my compressor over heated and blew the Circuit Breaker half way thru the big night. Its a 3HP/10 Gallon Compressor connected to the Air cannon which is a 7 gallon resevoir tank. Compressor fills to 115 PSI and refills at like 90 PSI I believe. The Air Cannon was set at like 30 PSI when fired. It was on a timed motion sensor so it only fired at the minimum every 2 minutes. I know Air Cannons are air hogs but any ideas on how to fix this problem? Bigger Compressor? Another resevoir tank between the compressor and Air Cannon?
