I certainly don't think more holes will hurt you and you've got a ways to go before you lose structural stability in the "barrel" for something like this.

The more holes the better really... :)

Make the largest holes possible, not losing too much structural strength.
Also, I think the holes would be square for optimal results, like only leaving a few bars of pvc left as structure.
Maybe even just saw out a piece of pipe and replace it with about 6 or 8 metal rods.

Video added in the first post to show flames and fired it directly at the camera. I just did it in my garage because I didn't feel like waiting for dark (have to work).

This sucker is loud!

You can tell how awesome a cannon is by the pressure used.

I wore plugs so it didnt make my ears ring but it would if I wasnt wearing any. It is very loud!

I'm using a Sony Cybershot camera, not a true video camera but good enough.

I hope I wasn't in that dream also.

Audio compression circuits in these cameras are notorious for yanking the meat out of a good spudgun blast.

Pitbull, I'm afraid the loudness doesn't translate very well on the video. The 4 way firing blast was cool though... :wink:
