Just a quick advisory to not leave your induction annealer unattended. This was an EZ-Anneal unit (no longer in business) that had an auto brass feeder. I smelled plastic burning and turned to see the unit on fire. From best I can tell the glass tube that the induction coil wraps around, broke at some point. 2 pieces of brass got jammed in the tube, not releasing and superheating the brass until the plastic caught fire. $1000 up in smoke. Could have been worse if I hadn’t been standing there.
