This is one of my cannons, rather a disappointment. It has dual sprinkler valves, modded and with way to much pilot volume. The barrel is roughly 5 feet long and is 3/4 CPVC. The chamber is 2 inch by 5 feet and it has a ball valve breach. I built it to get supposed great performance but the results were lacking. It was hard to aim and bulky.

Interesting setup you have there :P

Yeah a bit too much pilot and dead volume, but oh well, you can always salvage it for parts.

Swap the barrel for a 40mm one and get rid of the long pilot hose :idea:

Looks kinda scrapped together out of different sorts of crap.
But the setup looks nice.
What are the reasons of calling it a dissapointment? Lower the pilot volume, and maybe up the calibre and it will gain power.

It was more of putting it together because a) I had the pipe in my room, b) i needed a new valve anyway, and c) because i could. And what exactly are the middle pipes?

what were you trying to achieve by making such an ugly beast :wink: maybe you could get yourself a super long barrel and mount it on a stand to make it into an artillery type thing.

How can you have so much elbows/tee's and other fittings lying around?

I always only buy the parts I need so Ive never got unused parts lying around.

I have a job and most of the time nothing to spend my money on so I buy a lot of stuff when I go lowes or Home Depot. My mom loves it :wink:
