This is a great build to follow, love the pics. along with the explanations. As a sheet metal worker I would TIG weld, mostly stainless steel, aluminum and copper along with some steel. I liked welding stainless steel the best.
I love the tig welding too. I just bought some Stainless Filler rod. I had read that it was better than the regular steel filler rod, so I tried both. I found that I had less impurities in my welds with the stainless. Maybe it was coincidental, but for a few bucks the rods are sure to stay un tarnished as they sit for long periods unused in my shop.
My pal has his first off road truck race this weekend, so we've been burning the midnight oil trying to get his truck built. It has consumed all my time, so I'll be back on the sprayer Monday. He's a sheet metal worker as well! My welder and fab tools are at his shop now anyhow, so I can't even steal a few minutes out in the shop on it...
Still just sitting there waiting to get welded... doh!
