I think you are on the wrong frequency with this one OM. The world of
telecommunications must run on one master oscillator. Call it GOD if you
will. There is a heavily guarded master oscillator somewhere on earth that
keeps everything in sync. I think it is somewhere in New England. All you
have to do is get a feed if this master clock and phase lock loop all your
ham junk to this frequency. What do you think would happen to all the worlds
telephone, television and satellite gear if everyone had their own free
running oscillators? Chaos. I doubt you can cut a piece of quartz to any
predictable frequency without specialized equipment nor keep it at a
predetermined frequency without a very accurate crystal oven. Remove just a
pubic hair of quartz and all is lost.

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?)
