Yes, you just reminded me of a visit years ago to an optical works owned by
a friend's father. How do you mount an unfinished non-circular glass lens
in a lathe (of sorts) to finish it? Answer: you take some LMP alloy such
as you describe, melt it in a short cylindical mould, float the lens on
top, let it cool, and mount the cylinder with glass attached in the lathe
chuck. To remove the alloy later, place it in a warm water bath.
