re: Workshop fire -- averted . . . and a "whuf" question

Very similar thing happened to twice:
- first time when I was doing pattern routing with a dull bit. I was not connected o the dust collector.
The second time I was connected to the dust collector. most of the burning stuff were in my router box. I was concerned that some made it to the dust collector barrel. I took it out and emptied it on the drive way just to make sure.
I am sure I was rushing the cuts and talking too deep one.
