I wish to make a master oscillator for the shack, and am considering
cutting my own crystals in order to reduce ageing. Is there a source
of raw material?

Also, for temperature compensation, I am considering the use of bi-metals.
(I've never seen one, but what is the mechanism used in Oxley's
Tempatrimmer?)

So much for Radio Amateurs 'knowing' their hobby. The Cb'er makes himself
known when he blurts out a foolish question on this NG.
