    I tried to get a burner one going and while the electronics worked great the mechanical feeding was flaky. I have wondered about using a case collator dropping into something like this with a trapdoor to drop it into water.

    I (well my brother actually) built an annealer that uses 2 propane? torches. I must get a video of it running. I wanted to build an induction annealer but it all seemed to hard (and expensive) but this has renewed my enthusiasm to have a go

    Yea mate. Itís not too hard, the controller is the tricky bit. I used an arduino, happy to Share the source code if you wanna go that way. AliExpress has sharp prices and free shipping on most of the bits you need too so $ not too bad.

    If anyone's interested, got the timing dialed in for 223, 308, 270 & 300WM. Yellow is 650F and white is 450F.

    This project is pretty much finished now. video below of doing some 270 brass in free run mode.

    I did 75pc of 223 brass without pausing - the coil remains cool and the only parts that were slightly warm were the resonant capacitors on the induction board.

    ** if anyone is going to build one of these - The water cooled coil is an absolute must. makes such a big difference to heat as well as efficiency

    Cheers,
    Mark
