I need to make a two inch hole near the center of a four foot square
3/16" steel plate. It doesn't need to be perfect, could be slightly
irregular. Would a cutting torch be OK, or would the heat permanently
distort the plate?

What other methods would work? A plasma cutter sounds good to me, but
I don't have one. I guess I could take it somewhere and pay to have
it done.

Bi-metal hole saw would work great and give you a pretty good hole. Its too
thick for a slug buster.
