I thought I would share some video of my prototype annealing machine. I built it specifically because I can't afford a commercially made one. Including batteries and parts, I have about $100 into the whole thing including the stuff I ruined while making it.
The concept is simple, use a 555 IC chip to time the operation. A microswitch starts the timer. The timer system holds the bar in place with an electromagnet.
Right now, I'm running 5.5 seconds in the tip of a single propane torch.
Here it is in action:
