Not exactly world shocking news, but I've built a simple cheap CM still with StillDragon parts:
- 1,5m (3x50cm) 2" pipe, filled with stainless steel scrubbers (no filter disk or anything below)
- 2" Big Baby Dephlegmator
- 2" 180 degree bend
- 2" product condensor (long but short will be fine too)
- Optional: couple of thermometers in various thermowells (deplegmator water temp out, 180 degree bend, product condenser water temp out)
Result: ABV 95.5% (191 proof) from a +/- 7% charge. Success!
