you're over heating the case friend and you need to drop it into water. Before you go into a tirade I have done thousands of 17 hornet, some of the hardest to keep from splitting, and have never, yes never had a failure. the room needs to be dark and just when you see the glow start you drop in into water. your killing the zinc.

You are correct. In this video I was definitely overheating the cases. The cases must be heated to 700-750F, they begin to glow at 900F. I've come a long way with induction annealing since this video, check out the latest one in my videos.

ur heating the brass to far.
heat to blue, not red
-
nice. Looks like it'd be very uniform heat. Good idea to copy!

Where can I buy the device?
Or is there existing a blueprint?
Yes also heard that cooling it at room temperature just makes the brass softer. Quenching in water makes it harder.

That is true for steel, not brass. Brass will get softer regardless of how it is cooled and how long it takes. The only way to harden brass is to work it (this is why shooting and resizing the case will work harden and eventually split the case).

which frequency and current did you use?

The tool auto ranges for optimum frequency. As for power output, it's listed max is 1000 watts, but I was probably only pushing 5-600 out of it.

No, I did not make it. I am in the process though of making my own fully automatic version.
