I never said "set fire". I do know that he burned through the stainless as he had that bluing color to the stainless and the metal got paper thin which ended up leaving a small "weld-like" hole in the trim. I can see if he still has the piece and snap a pic of the result.
I could see one of those "expanding wheels" be somewhat dangerous for a novice to be using.
Same as a novice using a rotary buffer on a paint job ( DAMHIK) LOL
