[Milsurplus] IT'S FIXED! Or, How NOT ro clean a crystal.

[Scott Johnson]

I wouldn't worry about the epoxy outgassing, as long as you use good quality 
epoxy..  I would not, however use 5 minute epoxy, I would use masterbond or 
equal.  epoxy does not out gas much, it is by definition a stiochiomertric 
reaction. I use it regularly in high vacuum applications.  (we seal 
prototype vacuum displays with it)
