clean, yet serviceable?

Unread postAuthor: sharpshooter » Wed Sep 03, 2008 12:18 am

due to the fact that my newest piston cannon will not have a round back (oh, the joys of epoxy :P ), it will not be possible to attach a male/female adapter to make the piston serviceable.
Judging from various supah, and other valves enclosed in a "T" , I should be able to have a pipe pressed against a o-ring, held in place by several screws, and it'll hold a respectable amount of pressure right?
I hate to be stuck with having to use a hacksaw to service my pistons like JSR...

edit: had to change FMJ to JSR ... still stuck in the old spudtech days.... lol

If you build it just right you shouldn't have any problems. "Old Spudtech days" you should have known this, yes? no?

I use a piece of wooden dowel inbetween my sprinkler valve and spring. When I screw my sprinkle valve on there is about 1 threads lenth of tension pushing against my piston. My cannon fires nicely from 15psi to 100psi.
