[Milsurplus] Opening HC-6 cans ?

[Hubert Miller]

I found, or i should say rediscovered, a bunch of HC-6 rocks that i removed from a 1950s Collins VHF air transmitter i scrapped some years back. This set apparently used a crystal mixing scheme to generate the VHF  channels. There's abt 20 right in the 80m voice band but they all end on odd numbers like 3833.3 kHz. I would like to harvest the blanks and mebbe grind them to more popular defined channels like 3885. I recall in the past my attempts to open the soldered ones using a 100 watt iron didn't work. Maybe cutting them open? Some are not soldered anyway. What use: jeweler's blade coping saw? Dremel ? What think you ?
