I had to look in the waste to see where the ember was
that I had to poke out. Where there was that much smoke,
there had to be some fire.

The rototool spins at around 17,000 rpm. First few
passes went ok. I'll have to upgrade the bit and
take a smaller pass. Hell, it's a hobby-- no rush.
But setup on this job for a bunch of zig zags is a
drag. I'm leaving it go for a few days.
