lol uhhhh ya dumbass... you can implement a check valve into a piston... do a little looking around or better yet, use your imagination before you laugh at my idea.

and wtf? hot glue piston? what is this 2nd grade? lol

The actual piston doesn't have much to it... there are a few variations such as choosing between PVC rod, or turning down a fitting on a lathe to use that. I prefer the latter as it allows for a lighter piston. You then simply plug the ends with spigot plugs. Another plus with the fittings is you ca...

Looks schweet, very nice job! Way to come over to the dark side and start building guns with more power :twisted: I would have to agree with rmich, this does seem more of a diaphragm valve to me considering the placement of the barrel in the tee as well as the 'piston' you are using. Nevertheless, e...

Any updates?

All I can say is AWESOME! Nice to see some larger piston valves. You've inspired me to make a big bastard like this... although probably a 3" tee rather than a 4"

@ Spudthug - I accidentally had the trigger facing the wrong way when I was taking pics :P, however I think I like it just white and gray. @ VH_man - I actually have a setup where I have a 1.5" MPT to 1" FPT adapter and thread the 1.5" into the gun, thread a nipple into the 1" FPT and attach that to...

This cannon by Foxx uses a 3/4" valve to actuate the 2" valve... very nice, I'd suggest considering a setup like this: http://www.geocities.com/cain333_2000/c ... vlvmod.htm

I sell a valve identical to C19o that I advertised for sale over 4 months ago but cleaner and with a lighter piston for better travel for $40. It is a barrel sealing 2" tee with 2" threads and slightly over 1.5" porting. The piston is hollow, therefore light (quicker actuation), while still strong e...

lol I agree with you there... but this is the wrong thread you are barkin up since it is a thread dedicated to things that piss you off... hence the somewhat unintelligent statements made (again not aimed at anyone in general.)

Yeah, there we go, thx joannaardway!

Looks different from what I remembered but that must be it. Looks sweet, got more pics or a link to more? Thanks DR

lol didn't you make a gun with 3 sprinkler valves and 3 barrels very close to each other... like a triangle looking thing. Or if you didn't, do you know which gun I'm talking about? I was almost positive it was you who built it.

Hey DR, sorry to switch topics here but could you post the link for your Tri valved tri barrel tennis ball launcher? I've been looking everywhere for it and I wanted to take a peek at it again. Thanks DR

@ Flying_Salt, here is another way to implement your idea, however it would make the barrels very far apart and might not look as good as a result. Just picture the barrels and tee horizontal instead of vertical... I haven't quite figured out how to do 3D models... http://www.putfile.com/pic.php?img...

That image I have on putfile of the design of my gun I made on Google Sketchup...

and like I said, the only reason it took that long is because everything it proportional and accurate to .01 of an inch.
