Latest one has an auto feed with case sensor that can be adjusted to feed anything from pistol cases to large ultra mag cases. Case is made from plywood and painted to look nice, water cooling on the induction coil using a small water pump and radiator.

Anyone who is interested, google the GinaErik induction annealer. There are also other designs using Arduino boards for the timing and control, which if you are going to use an auto feeder, I would recommend.


The AMP is a cool machine and good on the guys for getting them out internationally. However, in my opinion, they are overstating and overcomplicating the annealing process, which is pretty simple really. Using 2 different temp grades of Tempilaq, you can fine tune the annealers I have made to get perfect and consistent results for a new case in a few min, risking only 1 or 2 pieces of brass, and often not ruining even one. I keep a log book of the settings for different cases and can reset the machine to a different case in about 1min.

In my experience, the flame annealers are a pain in the ass to setup every time, induction is so much better.

Spend a few dollars on Alex's book.
You will enjoy it guaranteed.
