The net result of this is a) …
… a ton of aluminum dust.
and b) nasty and irreparable damage to my shop floor, which used to have a nice clear-coated warning strip running under the 5-foot-high ceiling beam (which tends to crack you over the head when you’re not paying attention) but now looks like a bad case of Krylon acne.
This means the next project is to repaint the floor.
I’ll sleep when I’m dead, I guess.
