low power almost nice looking pneumatic

Unread postAuthor: ThSoLdIeR » Sun Sep 11, 2005 10:01 am

Alright, here's my newest almost nice looking and almost powerful little piston cannon that I've been working at for a LONG LONG LONG time. The chamber is 79 cm of 1" black iron, the barrel is 1/2" plastic electrical conduit tubing. The piston slides indise a 1" brass nipple, the bumper is a piece of air hose and the piston seat is a piece of union that had to be "loced titely" in place to get it to seal. First the pston just crack opened about 2mm even there was just a little friction but still seemed to be enough to make the gun not dryfire or fire loose projectiles at all. At this weekend I sanded the gaskets on the piston and now it has no friction at all, fires great. You would like to see the cannon now wouldn't ya?

So here it is

I would call it "looks like a good gun".

Nice gun and the piston valve is clean and simple.

wow... I'm proud of you spudstuff, you didn't mention that Pyro just dug up a year old thread!!

and to top that, you even commented a user that no longer browses this forum. You tell everyone NOT to do that!

what's happening...?

He is human after all. *runs down street screaming "NOTHING IS REAL!"

This a very nice gun to rival the work of schmanman and brian. Wonder what happened to it.
