Need plans, going to freinds house

here is a cheap design. get about 5 feet of 2 inch pvc, a 2 inch ball valve and a 2 inch end cap. this will be about $13 to build and you will get about 200 yards out of it . cut the 5 foot pvc into two peices. one about 2 feet (for the chamber) and the other 3 foot peice as a barrel. glue the two together with the ball valve between the two. glue a fill valve (just cut one off a bike tire) to the end cap ( you obviously need to drill a hole first). So from front to back here are the parts. barrel (three foot), ball valve, 2 foot pvc (chamber), end cap, fill valve. this can also be used as a basic combustion, just leave the valve open.

note- if turned into a combustion it can no longer be used as a pneumatic.
also, be suree to use pvc glue and primer and let it dry for at least 12 hours.

I don't know what your talking about 2" ball valves are expensive

and let it dry for 24 hours not 12.
