The only part about a coaxial that confuses me is how the end of the chamber is sealed off where the barrel comes out of it and is exposed to the open. Do you just drill a hole the size of the OD of the barrel into an endcap of the chamber and seal it with some epoxy or something? I want to build a coaxial real bad :(

You're right. I said the same thing. Unless they have some kind of SDR 1" that he used...
you could use a lathe a mill or a drill press to thin the wall of the pipe i thin. they've done it on myth busters.
