Good stuff, glad to see the ol pot working hard. :)
Few tips:
- DI is max -77C, not -90C ;)
- You may want to invest in a digital thermometer and mount probe on bottom of pot (see pic).
- Dice will cool best if you crush first, and maintain a few inches, packing down often.
- Use about 2 oz of methanol or whatever, as long as its 90%+
