This is a cannon that I improved upon from this...

http://www.spudfiles.com/forums/the-bac ... 18886.html

The thing on the bottom is a small hand pump... it takes a while to pump up but when i do... it'll shoot a golf ball 150 yards. I was really impressed with the power...

The changes I've made are...

new gb barrel

added a quick connect

put on the pump

painted it...

Not bad, Not bad at all!!! 150 yards with a sprinkler valve is pretty impressive. What pressures are you running it at? For your next cannon you should try your hand at a piston valve, you will be impressed with the performance spike. 8)

if you look at his last version you can see the fill valve at the bottom, so i assume that the pump attaches to that and is housed inside the tees.

Actually... I've already conquered the piston...

And I'm about to finish another piston gb cannon...

The pump is hidden inside the elbow, two tees, and another elbow. Connected to the bottom of the cannon...

Its the elbow closest to the quick disconnect. It doesn't have any epoxy on it.

The front elbow isn't actually glued on... it is the pump handle. When pushed all the way down it fits to the chamber. I might be able to get up a pic tomorrow. Its dark here right now...

edit... you beat me to it veggie... good job!
