Thread: DIY Induction Annealer

it's rough looking but works good. video of it in action at the bottom.



Video In Action

pretty much used this guys design for the induction part, but used a different controller and got all my parts off Aliexpress.
Induction brass annealer | Shooters' Forum

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.

You don't need 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. It’s 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.

just bourbon

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

Hi @MGNZ this is definitely interesting! Source code yes please and do you have some photos of the beast open? Parts list?

Awesome and Thanks in advance

Hi @300CALMAN,
some pics below of the inside and arduino pinout and also some links to the bits from aliexpress and the software source.

ZVS induction board
Display
12V 2A power supply
Cooling pump
water tube
1/8" copper tube
48V 600W power supply
current sensor (optional)
Radiator
cooling tank
controller

arduino software source code

Wow that's hiding a water cooler and all! Very impressive

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

That is awesome. @40mm a big one for 40 mm?
