Tbh that's exactly how it works with these things. Plants are way more tuned in than people give them credit for. Those three blooms on a rough Monday sound like they were looking out for you.

Nah, I gotta push back a little. Those flat sanders are actually great once you get the feel for them. The trick is letting the tool do the work, not muscling it into the wall like a regular sander. Sounds like you were holding it way too tight and probably had the speed cranked up.

Noticed the same thing with pretty much any kind of stubborn gunk... paint scraping, even scrubbing a burnt pan. You always gotta attack from underneath to get real leverage.

@robert_bell did the tool let you set any limits on time zones or just assume you're fine with chaos?

You ever try dunking the chisel in water every couple seconds while you grind... keeps the heat down and saves the temper. I learned that one the hard way too.
