Not really. Steel pipe is usually SCH-40, with the same dimensions as PVC. tapping is a breeze with steel as well, (well, unless you're using vice grips as your "drill" and "tap wrench").

That's because all you've built are small ones. :wink: My tater cannon with a 1.5/1.5 atm mix will "stomp a pneumatics dick in the dirt", (as DR say's).

Yeah. Bunches of people do it with copper. You just solder. All you need for soldering is a blow torch and solder.

OK IVE NEVER TAPPED PLASTIC UM IF YOUR MAKING A HYBRID (IVE NEVER DONE THAT YET EITHER) I SUGGEST YOU PUT A NUT ON EITHER SIDE OF WHAT YOUR PUTTING IN THE TAPPED HOLE IF YOU DON'T AND YOU STUFF UP THE TAP WHAT EVER YOU SCREW IN COULD RESULT FLYING OUT LIKE A BULLET WHILE FIRING ESPECIALLY WITH THE PRESSURE HYBRIDS WORK AT.HOPE THIS HELPS A LIL.

Please don't post in all caps.

@rl93 The part that holds the burst disk is called a union.

I wonder how much deeper the ocean would be without sponges.
Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.

You truly don't know what your talking about.
Even in a 200+ psi environment I highly doubt that your fittings would blow out. Unless your threads were janky or you didn't have enough threads.

And do they make npt nuts? You could fashion your own out of a ed cap and drill it.
