[Milsurplus] Metal to crystal bond

[hwhall at compuserve.com]

Might be worth a try!  Also makes me think of some HC-6 style cases I've opened where the crystal was held between to little wirespring clips - if some plating could be removed from the FT-241 plate, so that each clip only contacted one conductive film, could those holders male it work, too?
Someone have a bucket of crystals to play with?

I just opened an " I.C.A. " crystal holder from the late 1930s. This thing is about as large as a pocket watch,
and is easy - open, two nuts like on old dry cell batteries can be easily removed. There is a spring to maintain 
a force on the relatively huge metal crystal plates. This got me to wondering. Those notorious FT-241 LF
crystals, I understand one failure mode is the plate contact comes off. So I'm thinking, what if take one such
from the numerous defectives I have, and place that blank in this I.C.A. holder, would it resonate ? BTW, 
these type holders also under different brand names, white ceramic material, and have a tensioning adjustment
in the middle. Just for an experiment, I'm tempted to try this on.
