/diy/ - Do It Yourself

>>2387091
So I tried it out and it wasn't as effective as I remembered, see pic related. I made the coil for making twists in wrought iron, but couldn't get the whole length very hot. Keep in mind unlike a forge you are losing a lot of heat to radiation, so at some point even if you are moving a large piece through a small coil you will lose heat as fast as you can put heat in. Though perhaps a ceramic tube insert inside the coils could aid this.
Anyways my coil could probably be optimized (loops are pretty lazy but will have to anneal to get tighter), but first glance answer seems to be impracticable for heat treating swords with this particular unit (I have successfully heat treated 10"knives thus far). (240V, draws about 32A btw)
