Well took me awhile but here it is.....

It uses two 1kg Fire Extinguishers welded to 15mm(1/2") Galv Steel elbows, I have added a ball valve as a safety to stop accidental mis-fires. It sports a 1" Pneumatically Modded Sprinkler Valve and a 44" long 3/4" paintball barrel with breech loader. The camera tripod was purchased for $2.50 as it was broken(1 Screw fixed it :D) I don't use it to fire just for display. I have a schrader valve and a quick connect(w/ ball valve) as my filling station. The schrader sports a 9mm shell as its cover thanks to Schmanman :P . The Fe's weigh alot thats why they are balancing on the car. The breech is a simple hole in the barrel and a hole in a 1/2" coupling thing which is O-Ring sealed and can be tighten and loosen to seal properly.

SWEET!!!!
How powerful is it?
How bad is the kick?

Your toes are much better than the ones in that nasty toe thread on spudfiles.

LOL, Just look at the MDF board to see the power, they were fishing sinkers at 80psi! This thing can go to 145psi if I had a better air compressor(21L 2HP 115psi max)
The kick aint bad, I can handle it:D

very nice, how is the steel welded to the brass?

I like the schrader covers. I will make some more with rifle shells today. I could probably sell 'em, too. ;)

these tanks would be cool on an over under piston valve cannon.

Yeah I just realised I screwed that part up, I was going to get it brazed but instead the guy said he doesnt think its safe, so i replaced the two elbows with galv elbows sanded the galv off and the guy welded them. I was going to do over-under but it would of jumped the cost by $60-$100 as galv fittings cost quite a bit.

Well $15NZD($8US) gives you one 15mm(1/2") gavl fitting e.g a 15mm elbow. So I would need probably 20mm fittings,then I need to make a piston and the exhaust and filling station and compression fittings for the barrel....
