Hi, Ron,
Tom has done just a small amount of practice welding so far. I don't think its art he is interested in (sigh); its putting I-beams together for his water tank surround.
Yeah, the rocket stove is so cool. I ordered one from the guy on the you tube (came from Hawaii!..go figure). It works great, so I'm building a double one with a brick surround as part of our bbq area. I bought black stove pipe for the thing. Hav'nt been able to cut the pipe. Its a lot thicker than a tin can.
