I got this nice thing



now, I need air. What's the right pressure for Alu? 90-150psi?
Can I use a PB or scuba Tank, for small parts like a Gunbody?

acidcustum is for the Gunfight
pressure also depends on what media you use
PB or scuba tanks could only be used with a low pressure reg and you wont get to long out of them

Just grab a small air compressor. I have a small ~3 gallon craftsman that will output 90 psi. That way you wouldnt have to worry about an LPR and filling it up everytime you want to use it.
