    Whoa! I've had my belt sander start smoldering a bit when sharpening plane irons, as Ken did, but Chuck's idea of an electrical fault seems much more likely. Good thing it happened while you were there.
    Cheers,

    another question you say you were sanding poly between coats, is the poly solvent based or water based, if it was solvent based are you sure the poly was completly done out gassing before sanding. I have had poly on rags spontanously cumbust before just due to it being hot.

    That could be a possibility Don. I'm using Minwax fast drying polyurethane. On the can it says to let dry 3-4 hours, then lightly sand. When I sanded, it had been just over 4 hours and felt dry to the touch, and it was producing dust. I would think if it was a little wet yet that it would have balled up on me, but who knows. I'm getting ready to try a dry run with it and see if I get any sparks.

    Sorry, it's solvent based. I ran the sander for awhile in the dark and didn't notice any sparks at all.

    Larry, I took a 2x6 into the laundry room in my basement. There are no windows in there, so it was dark. I had the dust collection bag off and I sanded the board for about 10 min. I didn't see any sparks during that time.
