Thread: Maybe a annealing machine bones?

@gadgetman and any other electronic knowledge folk..... would / could this be the beginning of a case annealing machine ? (Add timer, power supply, case holder.....)

@mikee has put one together.

@Beaker, I’ve got one of those. Project has stalled. You can have it if you like. Lots of good info here.

Induction brass annealer redux | Shooters' Forum

Thanks for the offer - but all it will do is shift the location of said stalled parts......

I was just looking on aliexpress for a few fishing/boat things and it popped up. Maybe of interest to someone with time etc...

That thread is full of good info to.

I think an Arduino to control it and maybe a vehicle central locking mechanism to work the trap door. Most expensive bit will be the power supply.

I would be keen on a go. Wish there was a simple way to mod my $50 Kmart induction burner to make it higher frequency and work with brass. That way you could do about 40 at once.

I'll buy one from you. Don't care on what it looks likes - function over form.
Just make it work, and little effort from me.

Oops. Seems a few bits are on the way.

ok, basically its a beat frequency oscillator connected to a power supply and a coil. no 300calman. you cant do 40 at a hit as the neck needs to be surrounded 360 deg.
big issue is that this is an electromagnetic device. different metals will be affected differently so the mix of copper and zinc to make the brass is one issue, then how much nickel is added and/or plated on.
i'm new to the reloading issue but when it comes down to magnetic induction i'm pretty ok.
whats posted will work, but its going to be a whole lot of possibly dangerous trial and error to make it work

I can remember being in the power electronics lab with a guy trying to make the first switch mode welder. A couple of times a week a $50 semiconductor would explode and send molten bits 2-3m across the bench.

This is why the A.M.P. costs what it does. He’s done all that trial and error and documented the minimum annealing needed to achieve the required softness, and programmed all that into the machine. Look up your cal and brand of brass and away you go.

ahh gadget wait till you see selenium diode ignite, its like the ultimate dog fart from hell

a very toxic dog fart

Good on him, nice machine and if I had 10,000 brass or more to anneal I would get one. I don't really need one, just want one to play with.
