I've got a hypothetical question for ye:
Let's say, <I>if</I> I wanted to build something similar, what's your thoughts on aluminum tube 3" ID, 3.5" OD, (with standard tolerances taken into account), blocked off on both ends with 1/4" aluminum plate bolted together with 3/4"-10 threaded rod and sealed off with Buna-N gaskets? Also, 2" female SCH-80 steel threaded adapters would be welded into place, (with supports from a coupling and some aluminum I-beam on the inside), on both sides to attach the barrel on the front and to vent on the back? That's the simplest way I can think to pull of an aluminum gun. My calculations say that this pipe, (with the aluminum 35,000 PSI yield tensile strength), would be safe to use up to about 760 PSI. What would you say, necessarily, that your gun would be fairly rated to?
Also, if you're looking to add some more stuff to this, I know where you can get a pneumatic cylinder, (double acting), operated elevation system for under 100 bucks. That'd be neat, eh?
