Chamber-SCH40 3"x3'
Valve-Modified Sprinkler
barrel-SDR26 2.5"x4'

I know a supah valve would more than double preformance, but there is always next project!

I'm sure it would increase performance by a factor of 10 :D
Also you didnt need to post again for that picture, could have just put it in the first post.... otherwise it looks good.

Gotta love the classics. :wink: If that's a 1" sprinkler valve you're not getting terrible performance (a few more pictures would be nice).

About your Supah valve desire: I would build a barrel sealer myself rather than by a Supah valve. Even with a 1-1/2" porting piston valve you would be getting approximately 9 times more flow than the 1" sprinkler (using SDR-21 for the barrel port).

Of course, you could build a 3" or 2-1/2" porting valve for up to 28 times more flow than the 1" sprinkler and unrestricted flow into your barrel. :D

So would a piston valve!

AnotherSnappedLine, did you have any problems with the file manager? Other wise you get a option to use the 'edit button' after you post.

Same thing :)

That sprinkler valve really doesn't have enough flow for such a wide barrel, but it will be a fun launcher and I predict a lot of destroyed cans :D

Though it isn't a super high preformance gun(compared to others), I LOVE IT! At 100 psi it goes about 75 yards with a ton of power left! That's fine for a first.
