I've gotten good advice here in the past. Maybe someone can help me with
this problem

I have a rather expensive oven mercury thermometer. When using it in a
combination MW/convection oven with a rotating surface to test the oven
temperature, evidently the vibration caused the mercury to be widely
scattered thoughout the glass column. I read a site info on this problem
but none of their suggestions helped. Tapping it into my hand to move the
mecury, heating it, etc.

The only other idea I have is to somehow fasten it to an electric drill and
spin it so the centrifugal force forces the mercury to the bulb but can't
figure out how to securely mount it.

Any better ideas?

Get someone who's over 40 years of age to show you how to shake down a fever
thermometer, or find a video online somewhere. Here's one:

You will probably have to do this repeatedly, shaking first toward one end, then the other,
but eventually you'll get all of those different blobs of mercury back together.
