[Frizzle Fry]

I don't seem to get shrinkage from grinding. Maybe I use less pressure. I have been taking the welds down to near-surface level with a grinding wheel, then hitting them with the flap disc, then 80 grit DA.

The key to avoiding warpage starts with the weld itself. On thin stuff I tac-tac-tac, jumping around to avoid too much heat in one area. It ends up looking like the steering column pass-through pic in my previous post before grinding. Not the prettiest to look at but it all gets ground smooth anyway.
