Thread: DIY Automated Annealing Machine

I'm keen.

I'm an electronics retard, so the BBQ rotisserie appeals to me as you can't get any more easy than plugging into the wall socket and flicking an on switch. But I can definitely see huge advantages in your system, especially if using multiple rifle calibers that each require a specific annealing time.

Once the couplings arrive it will be all go, and I'll take pics as I assemble it. Until then there is nothing really to take a picture of but a wooden box and a pile of electronic bits. I have actually aimed to make it as easy as possible to use the arduino and I'll share the code as I have been pinching bits n pieces of design off others I like anyway.

You can just buy wee control circuits instead ready to go for $4,

but I wanted an arduino project to learn on.

Small step forwards. Its all connected up with a micro chain and sprocket from a meccano set. It runs sweet, but the reduction drive on the rotisserie is a bit noisy...but that's not really a big deal.


I'll look at finishing the rest soon. Times been in short supply lately with all my focus directed at my harley in recent weeks.

my induction one is progressing slowly too. Its the "agricultural model" made from scrap electronic stuff lying around work. Decided to be different since everyone else uses a flame

If it even 1/2 works I'll be bloody amazed

Would post a pic but is rather embarrassing looking thing

Hi mikee, induction is by far the better way. I simply don't understand electrical circuits well enough to do one safely.

Induction has many advantages over flames. More consistent hardness is achieved, quicker set up, easily swap from one calibre to another...jealous!

And mine may well end in a cloud of smoke with electrons lying everywhere!!!

The "Model One" is built out of odds and sods I have lying round so initial testing could be fun since I only have a rough drawing to go from and which the component list has been modified to "what ever I have lying round for free"

If it all works I will buy a couple of proper kits ex UK to make it look nice.

But for now cheap an cheerful will do

This is an induction annealer working for those who have not seen one
