then you just use a pressure gauge with 1/4 NPT threads and put teflon tape on it and screw it in tight.

Is teflon tape neccesary (for a schader valve)? If so, where would I get it? One last question: What size hole should I drill for a schader valve (I am planning to tap the hole with the valve.)

Ok, what the flip! How have you been on spudfiles so long and not found out how to drill and tap holes!!!! All you do is get a hole drilled to the size your tap says and then tap it, take the tap out, teflon(which you get from your local plumbing/home improvement/home depot store) the bit up, and screw it in!!!!! IT IS NOT ROCKET SCIENCE!!!!!

o shut up squeaks. Flying Salt you could probably get by with not tapping the schrader into the chamber. Just drill a hole a tiny bit smaller then the threads and then tap the pipe.I strongly suggest practicing tapping into a scrap peice of pipe just so you know the size is good and so you don't mess up of your cannon. You don't have to use teflon I guess but it could leak but you can get some at homedepot for like 1$.

Ok, what the flip! Well maybe he just doesn't pick things up as fast as you. You don't have to TYPE IN ALL CAPS AND PUT A BUNCH OF EXCLAMATION MARKS AFTER SENTENCES!!!!!!! You could have just explained it nicely.
EDIT: I guess i was too late :lol: .

Just get along now fellas. I didnt know how to do this stuff when I did my first pneumatic and all of you did as well. So lets not get over excited about a question and just answer it.
