Metal to metal joining

[flamerz14]

I am building a aluminium/copper gun but my problem now is how I should join the female thread adapter to the barrell, attaching the bushing to the chamber, endcap to the chamber and is just putting teflon tape on threads able to hold pressure yet make the barrell detachable as well?[/list]

Yeah teflon will hold the pressure, you will just need to replace it after every time you take it apart

what abouts of joining the female threads to the barrell and joining endcap to the chamber and joining the bushel to thechamber? sorry but i'm a real noob pipes..

would using metal epoxy work? I saw a pack that says it can hold up to 1500psi once it has cured for 24 hrs. and btw, is just using pvc solvent cement safe for a pneumatic?The guy at the hardware shop says it doesn't need primer..plus it cheap.Only SGD$2.20 a small can.

guys at hardware store are dumb asses never belive them. they will sell you dwv and they tell you only cement. You need primer. Or else your parts could blow off and injure someone.

PVC solvent= cement? an what about the etal epoxy? is it safe?

[pyromaniac]

cement is also a solvent but you need primer and cement. primer is a much better solvent.
