Hi Dan. I've used simple heat treating over the years for various welding
jobs, and even done some basic tempering with old school blacksmith techniques.
It's fun if you like metalworking. I'm curious to see what gets done to Jim's
cone, and how much distortion it causes. I'd guess that for a piece like Jim's
cone, it would be prudent to clamp the cone assembly to minimize any tweaking of
the part, but with a good oven, that may not be needed. I look forward to any
info Jim can give us on the technique and process as it's applied to his
piece.
I've found pre-heating especially useful when welding cast parts, with a
long and slow cool down period.
