Finally have the automatic case feeder up and running. It really speeds up throughput!

Yeah, was thinking the same thing. Or widening the slot a bit to accept slightly skewed cases. The orange outer wheel is removable without tools to allow for different case size versions to be...

Much better feed reliability with 260 cases.

Still have a few feed bugs to work out, but not bad for a first run.

Quick update on this project. I'm starting to work on an automatic case feeder design add-on for the annealer. The plan is to 3D print the parts and provide the CAD for others. The feeding mechanism...

I have moved all the induction annealer build documentation, parts list etc. to a more permanent website as my dropbox links keep getting broken.

Nice work JohnD!

I have a couple of blank PCB's left if you're keen to build one? I could also build one up if needed.

Some info here for the coil i wound for my setup:

It really depends on the idiot :P I know some complete idiots that would probably electrocute themselves or burn their house down.

It definitely requires some practical skills to build it. Making...

Still waiting on the second lot of Arduino boards to arrive from china to get out to those still waiting. The boat from China is slooooooow at the moment.

14 NZHS members are building annealers -...

Thanks for the follow up PM's. It's cool that quite a few members are keen to build one.

For anyone else interested, this is how the costs worked out for a small PCB order:

1. Blank PCB - $17 -...

Well, the real things have arrived.

For those that expressed interest in blank PCBs or built units, send me a PM.

Thanks for the feedback. Looks like there are enough interested people to justify getting some pre-assembled units out of China. I've made some good progress on it - sending out for quote today.

I've been getting quite a few questions from members wanting to build an annealer like this one and most people seem very capable of building everything, but the electronic controller is the hurdle....

copper tube $5.95
coolant tank $11.26
radiator $10.80
48V supply $49.87
hose $4.34
pump $5.92
12V supply $3.58
LCD $3.21
ZVS $39.07
arduino controller $4.50

Video links are broken - put them on Youtube instead.

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...

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

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

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...

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

pretty much used this guys design for the induction part, but used a different controller...
