That is an ingenious design for a lower power compressor, as most people will be able to use it. The only reason I have an air compressor is for pressurizing my in-ground sprinkler system and filling tires, oh yeah, and shooting spuds...

I recently made a golf ball barrel for my pneumatic and was wondering at what different pressures people shoot golf balls at.

Co2 in a 12 gram cylinder is NOT even close to 900psi. What are you guys smoking??? Even the paintball cylinders are well below that. Edit by MrC: After a few hateful emails from this guy, he has finally acknowledged he is wrong. Apparently he made the above claim on a whim with no evidence or knowl...

If it still leaks after you connect it to the compressor, try making the equalization hole smaller. I put epoxy over mine and then made the hole with a pin in the epoxy before it hardened.

If that is an end cap(which it looks like one) cut it of get a reducer bushing(looks like it is 2" to 1") and put the barrel in that. Then it won't leak.

sch.40 PVC does NOT explode at 100psi first of all. If you will be operating the gun at higher than maybe 25 or 30 psi, you really should be using a PVC airtank. I shoot potatoes out of mine and I have about a 3.5ft 2" chamber that REALLY puts a lot of air behind the spud. 1ft of 2" PVC is not enoug...

I fixed it. It was because the equalization hole was way to big. Now my cannon works like a charm. Powerfull as hell

I've read the entire topic on sprinkler valve troubleshooting and still my modded valve leaks all the air out of the blowgun. Any other ideas would be much appreciated because I am using a 1" ball valve in the mean time and it isn't phenomenal.
