[JMS] Grinding crystals? Is an acid etch possible?

[Joe Rubin]

I love it ! No special equipment needed. Only a GOOD micrometer (not the 
inexpensive inported junk) and a frequency meter. Of course you could use 
one of the later digital readout receivers calibrated by comparison to WWV. 
Grind a thousand or two orbits... Day after day...Takes lots of patience... 
Try different grinding compounds... Lots of fun. Thanks for the other 
website info... 73   Joe  W4CBJ/WX4TRA.
