Where's that valve?

I don't have the shop to build something like that! Or the knowledge for that matter.

hmmm, i might just do that...., shouldn't be too hard to remove the oring from a union, add a belt groove to the barrel, grease the union with silicone grease, slap on a motor, and go...
thank's for the idea
look for a finished cannon about this time next year, as i have a concept that's eating up most of my time right now...

EDIT:typo's

The notion of spinning the barrel was one that came up during one of those <a href="http://forums.spudtech.com/topic.asp?ARCHIVE=true&TOPIC_ID=7853&whichpage=3&SearchTerms=barrel%2Cspin">electrically fed strafer threads</a>, on a small scale it should be easy to do but for a full size (3/4" caliber onwards) spudgun, there is a lot of inertia to be overcome before you have barrel and projectile spinning at the sort of velocity that will make the spin imparted have any effect on stability - meaning a very substantial motor and drive assembly.

Also, consider that everything has to be properly centred and balanced, otherwise it will shake itself to pieces.

i know FMJ, my post was meant to be a sarcastic joke, not a real attempt to do anything [:p]
