At the top of the page there is a SEARCH function. Learn it, use it, live it, love it, but never abuse it!!

If possible, I would like you to loan me 100 dollars. If that is possible it would be greatly appreciated by me.


Thanks


Matty. :D :D :D :D

ooooh burn....
Mate best advice, go to bunnings and grab some pvc or steel/brass fittings depending on the pressure your using. (pvc for 0-150psi + anything above that use steel) buy a Quick Exhaust Valve (QEV) off eBay/local pneumatic shop. Exhaust valves are basically a ready made piston valve. it can be very frustrating designing and building a piston gun because you have to get the piston just right or the valve will fail. pilot the valve with a blowgun or ball valve and your golden.

Would just go to wast since none of em search, when you make a account it should show you the how to use search thread then you have to do 10 searches before you can make a topic/post in a topic, it would also stop spammers.
