I tried to cut the plastic out for use as a pressure vessel and just use it as a barrel... then use 1~2 of the craftsman pressure tanks instead, and manifold them together (if i use two) to increase the flow rate (they have a single 1/2" port)

However, i keep having trouble figuring out what kind of threads go with what.. NPT, NPTF, BSPT, I seem to go in circles and get confused.

Anybody out there good with pipe threads?
