I have used various annealing machines for years. The Benchsource was the first I had. I built my own Annealeez, then bought a Giraud, upgraded that with an Annie induction annealer after piloting my own induction coil, and most recently bought an AMP + Amp Mate.
Induction annealing is the “bee’s knees.” Most consistent method, and the automated feeding process means I can set up the machine and have my hands free to do other tasks in my workshop while it does its job.
