A friend and I got tired of using a torch to anneal brass and there's enough information out there to make inductive case annealers if you don't mind tinkering. So after a bit of experimentation and accumulation of various parts we have our setups. We completed the following annealers from the leftover components and are now for sale. They are primarily water cooled but there is supplementary air cooling. They're compact and capable of annealing a few hundred .223 sized cases in a session. With some ice a couple hundred 'magnum' cases can be completed in a single session. They are not automated or running off timers. Once plugged in, a manual switch turns the work-coil on. For a point of reference I annealed 300 .223 Rem cases in 21 minutes.
*SOLD/SPF* The first one runs off two 12v batteries. It has built-in ~20 amp over-current protection, but can easily be connected to a suitable 24v power supply instead. It has a standard UPS battery pack connector for the main power.

*SOLD/SPF* The second one is a simpler, more compact design...
There are several expensive commercial annealers with lots of bells and whistles. Both of what I have are functional and cost little. They can be improved upon, but this is as far as I have gotten using up the spare parts.
For the first I'd like $90.
Shipping's extra but I think I can fit them in a USPS medium flat rate box.
The Guts of a couple of the prototypes:
You can melt the brass if you like. This 30-06 took about 9 seconds to heat this hot:
No, that's not the proper temperature to anneal brass, it's just an example. .223 and similar cases will heat up much quicker!
