Induction Annealer - Almost Done!!!

That is cool - how much current goes through the coil??

Also, what frequency is the oscillator?

Itchy,

That is really slick, nice job!

Excellent job sir!

 

[bowfisher]

I need one of those!

CatShooter,

The frequency is about 100KHz. I doubt the results of my first attempt at measuring the current. I don't believe the numbers. I'll try another method.

The current in a lightly loaded resonant circuit can get incredibly high

I don't know what Lapua uses but here's a few videos of manufacturer's using gas flames for annealing.
