Thread: DIY Automated Annealing Machine

Something I've always wanted, but never been able to justify. So as always when stuck in this situation I'm going to have a crack at making one.

I've made a start, and am waiting on a couple parts to arrive to finish it off. If I suddenly delete this post, you'll know I jumped the gun and shared this to soon and I have failed...and taken to it with a hammer. But if I post more pictures, then you can assume it's all going well and everything's rainbows and ponies!

Anyway, the idea isn't original. It's been done before, but this is my version of it:


Step 1:

Buy a $3 cake tin from the warehouse.


Drill a hole in the centre (you can see my making out above, two right angles at any point on the circumference always meet in the centre).

Then cut a slot out of it. The size isn't that important right now, it will possibly made larger later on after testing?

Step 2:

Purchase a BBQ rotisserie, these have a small reduction gear box inbuilt. They are cheap and designed to run for a long time, plus they are cheap



Connect it up to your cake tin and you're about half done.




step 3:

Time to make a stand! Not about hunters rights or the evils of 1080... no, a stand as in something to hold the above parts.



MDF, the back of a hilux as a work bench and a skill saw...can you get any more kiwi male than that!







Motor all mounted, just use brackets that come in the kit with the rotisserie (note I'm not using the term "spit-roast" just in case @R93 goggles it).


Step 4:

Getting the cases into the cake tin.

To do this, there will be a basic hopper, with a timed wheel that will collect and transfer a brass case from the hopper
and into the rotating cake tin.



Yes it is a skateboard wheel...but what did you expect, the other main component is a $3 cake tin!


Step 5:

Ummmm this is where I'm waiting on some trademe purchases to arrive so I can finish it.

So that's all for about a week while I'll wait for couriers to arrive.
