Thats are cool little cannon kinda does look like a M16. I am going to make a piston cannon soon too so I hope it turns out

Yeah dont worry about it man. If they have not posted in that time then they are long gone. This hobby is very addicting. I vist this site every day even though i dont post a lot.

Looks like a good idea too me. I know my cloud at 100 psi fires way to fast and can get expensive, I would say about a 3 round burst also.

Yeah man putting your head infront of anything that shoots a projectile is just a dumb idea people can get maimed or killed, by accidents.

Sweet gun. It looks like you have put lots of time into it.

I just built a new combustion. It has a 3 inch chamber that is a foot long and that goes out to a 1.5 inch barrel that is 5 feet long. I was wondering should I deacrease my barrel size? And is this a good setup? Hopefully I can post pictures soon

This is my plan I want to have a 6 inch or larger around tank thats about 5 feet long. That is connected to a straight 1 inch sprinkler valve. The barrel would be a 1 3/4 pipe about 5 feet long able to shoot golf balls. I want to make a pneumatic that has the most power and range, I can possiblely m...

Very interesting....Pimpman....There is quite a few stores near me that sell 1 and 3/4 pipe. And yes it is PVC. These stores are in Michigan....In fact I use this pipe for my golf ball barrel.

On some golf balls they have a inner core, witch is slightly smaller than the golf ball its self, this should fit in the 1.5. Or you can go buy a 1 3/4 pipe.

Thanks for the advice.

I use Right Guard deodarant. It has lots of power, without tons of residue.

I want to build a pneumatic cannon, My question is if I have a 6 inch diameter tank thats 4 foot long and I have a straight 1 inch modded sprinkler valve. That goes down to a 1 inch barrel, Would I be pushing too much air through the barrel and it could possiblely explode? I have built preumatics be...

This is a horrible idea, Iam on a airsoft team and we play with guns that shoot 500 MAX. Anything more than that and goggles are going to be broken and people can be seriously hurt. My M16A2 shoots about 420 and I can shred pop cans at that speed Whatever you do be safe.
