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 a
nd
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?

TIA

To reinstate the column, you need to heat it so it reads maximum/
mercury goes to the top of the tube.
If you examine the tube, at the end opposite the bulb there is
usually another void to prevent the bulb from bursting when this state
is reached.
Do NOT overheat.
If there is no void, do not let the column expand to the end of the
tube while you are doing this.
And wear eye protection.

The reason the mercury column has broken is that it is unsuitable for
a microwave, the metal has boiled so making the gaps.

The magnatron was not in use - the oven-only mode uses a heating element
only.
