I found a discarded bead frame rail in a dumpster that I used for the stand. I just did a very quick fab job cutting the sections and welded them together. I laced four spokes into the wheel, just enough to support the rim as I turned it gently. The torches are propped in position by large c-clamps.
I needed to keep both torches at full to get the rim to come up to temperature. I think three torches would work better.
I used this infrared thermometer
from Harbor Freight
to monitor the rim temperature.
Anyway, after two coats and lots of spinning I was really surprised at what came out.
