What would be the purpose of putting fiberglass over PVC?

there is no fiberglass over pvc. the cannon IS fiberglass. the bushing is just in the fiberglass because they dont make fiberglass bushings, and if they did they wouldnt be practical for this.


edit- he can get about 200 to 300 feet on a good shot (with a foot ball).

not really, more like a whophth of air rather than a bang. its impressive to watch fire because there is a puff of smoke.

yea theres videos somewhere. Think they're on the old spudtech forums. This thread seems to get bumped on a monthly basis. I don't plan to make any changes to this thing. "Hi" is it even still down there?
