Thread: DIY Induction Annealer

Just got my 48v power supply today. Ordered on the 22nd of April from AliExpress.
There is light at the end of the tunnel!

I ordered mine on the 15 March, and it has supposedly left China and in transit to NZ but that was on the 22 March. I have a funny feeling it aint turning up any time soon. @Sonicjoe did you order the one listed by MGNZ? or another shop ?

Same one listed.

I’ve had 3 of my 11 packages arrive so far, including the 48v power supply. Mine was the same one MGNZ listed

Thanks guys I will try them.

What’s every one going to make their boxes from or use To put the bits into?

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 - keen to see what everyone comes up with!

It really depends on the idiot 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 the box, making a case holder and dropping mechanism if you go that far, wiring the electrics etc.

IMO a practical Kiwi who tinkers in their garage, services their car, does work on the house should be sweet - it's definitely not an off-the-shelf product.

The programming can be setup for any oddball case. The 2 variables are anneal time and case height within the work coil - both of these are dialed in by the user using Tempilaq.

Secondly, can it be programmed to do a couple of wildcat cases? I have a m1 carbine case necked to 17 cal and a slightly shortened
6.5 carcano case necked to 22 and 6 mm.

Thanks

What is the internal diameter of the new coil we need to make? Same as the one that comes with the induction board but just a smaller tube?

@Mick Hunter the diameter is a lot smaller .... more like a broom handle (28 mm )

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

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

Here is my annealer using MGNZ's shield design. I have mounted it all in an ACM case I designed.

The blue LED you see when the annealer is running is taken directly from the ZVS board to give a visual clue that the board is working ( or more correctly.... hasnt stopped working should the solid state relay fail closed ...letting the device run constantly ) Which was an issue with my first device.

MGNZ reprogrammed the mode switch for me so I can run the drop gate on demand function ( arduino codeing is still above my intellect )

There have been several variations to what I now have .... starting with an old PC case then onto a wooden box and settling on the ACM paneling
The arduino shield was the real game changer for me and allows for a host of very available and low cost features, the servo making for a very simple drop case mechanism, an area of design I had struggled with.

Very nice.
Haven’t started building mine yet. Still waiting on the temp sensor and the water pump but fear the water pump at least is never arriving so may have to look locally or have another go at aliexpress.
Nice box, is that Ali angle it all screws into to hold it together?

Nice work JohnD!
