realistically do it, if at all.

Use a OA torch with big rosebud and heat the bulge to dark red, let it
cool and shrink

This is great info, thanks. I had heard this before, but didn't
remember which side. Now that you say it, it makes sense. My welding
table top isn't as massive as Ig's, 30" x 8' x 1/2", but has a 1/8"
bow in the other direction. I bolted it to the table frame, so easy
to remove (with an engine hoist). I do have a weed burner.

Thanks again,
