Recently my QEV arrived in the mail (courtesy of Mr.Plow) and I got right to building. I had bought all the parts beforehand so I could finish it the day I got it.
The barell is 48 inches of ½ pipe and the chamber is 36 inches of 1 inch pipe. I have also a dual chamber made of 2 sections of 1 inch pipe, each being 24 inches in length. It is exhausted by a ¼ inch high-flow blowgun and is filled by a ¼ inch ball valve. It's pretty fast shooting to, I can get off 20-30 shots a minute.

The QEV is a ¼ ported Schrader Bellows QEV.

Not to sound like an ass or anything, but the proper term is soldering, although I bet you could weld copper.

i dont think you could, its too thin, you could braze copper though

Copper can't you weld with a mig/mag/stick welder,because its to tin and copper melt a 1800°.Steel melts a higher temperatures
You can only solder it and braze it.
