[Leica] lost the dot - help

[pklein at 2alpha.net (Peter Klein)]

A few years ago, Sherry Krauter was nice enough to send me a red dot to put 
on a lens I'd bought without one.  If I remember correctly, she said to:

1. Clean out the depression into which the red dot fits, using acetone.
2. Rough up the bottom of the red dot and the depression on the lens mount 
a bit with an ordinary pin.
3. Use Super Glue--one teeny tiny drop on the point of the pin, spread 
inside the depression, to affix the dot.

She was very emphatic about not using too much Super Glue.
