As I have mentioned here before, my father passed away in 1998. When we sorted
his things, I got a lot of tools and parts of various sorts. He was somewhat of
a hoarder although in his later years he had a regrettable tendency to purchase
Taiwanese bargain bin tools instead of the good stuff.

Last night when I was going through some boxes, I found a Craftsman 572.610010
rotary tool. It looks like new. He probably never used it. When I turned it on,
it ran for a few seconds, and then the chuck stopped turning. The motor
continues to run just fine. The chuck is free-wheeling.

When I opened it, I found that there is a plastic or nylon sleeve that couples
the motor shaft to the chuck. It was completely disintegrated from age. The
problem now is that I cannot find a parts list or even a comparable parts lists
that shows the part. If I can't find the part number, there is no chance of
finding the part. It's probably not available anyway, but it's worth looking.

It looks like the trash can for this one.

I know that tools don't last forever, and I know that manufacturers cannot be
expected to supply parts forever, but what aggravates me is that the Sears parts
site does not even list the model.
