Duo-Art Motor is Overheating

Well, that's what I said.  But others were wiser, as usual, and there's
a non-contact infra-red thermometer available at Harbor Freight Tools:

There's a tiny link there for a PDF of the instruction manual, and on
that is a reference to a place called zytemp.com, which has a marvelous
variety of these things.  I gotta go get one!
