Damn! Thats strong for being so small! Use the barrel for you pnuematic and it would be way stronger than this. Dont shoot at street signs and put a shirt on. Please.

Indeed, sorry about the signs sort of didnt think. I will use 40mm for my pneumatic but what i need to know is weather to mod my sprinkler valve or not?

Speaking of which, will sprinkler valves preform reasonably well in an un-modded state?

Its ok, but it will reduce the power, and flow. It's something you want to avoid.
edit: did you use primer at all, or was it the clear kind?

i would definatly reccomend modifying the sprinkler valve, it makes it so much more powerful for only a few dollars extra.

Those are some nice shots. Did the tree have the red marks a few days after or like immediatly? That is really cool. Great job for your first cannon it has a cool design and is very clean. Where did you get 40mm pipe? I guess you don't live in the U.S.

Thats a realy nice looking cannon... Good Job.
I recomend modding the sprinkler. By the time you buy the switches the box the wiring and the electronics it prob would be the same price to get a fitting and a airgun anyway. And if you did a gas through stock it would reduce the efficiancy.
Basically, i just repeated what other people said but i didnt realize that till after i wrote it

Dang that looks quite nice! The chamber seems a bit small. With a larger chamber you will get more power and you might be able to put a hole in that road sign.
