DIY Annealing machine using Arduino and steppers.

I put together this Annealing machine which uses Arduino and a stepper motor as it's primary mechanism. It is a rotary base system which also has fully automatic case feeding using my Dillon case feeder.
Here is a link to the GitHub project. There you can find the Arduino code and non-electrical engineering schematic.

I am totally impressed, I wish I was gifted. If you ever sold one I’d be your first customer 😊

[@sjseth-builds]

Wow, thank you!

"Roughly 3.1 seconds"... 😂 Spoken like a true engineer brain. Freakin awesome video, man.

[@sjseth-builds]

Thanks man! I figured saying 3120 milliseconds was a bit overkill.

[@jerrybassett1630]

This looks very thought out you should think about building these for sale,I would buy one.

[@sjseth-builds]

Thanks for the kind words Jerry! I think building them for sale would be easy enough to figure out, but the logistics and support make it a full time business and I already have a full time job. For now they are just fun projects for me.

[@franprinsloo8885]

Hey man !!! This is hands down the best self made annealer I have ever seen . Well done man the craftsmanship is insane. Would you mind me contacting you for some questions i have regarding this?

[@sjseth-builds]

Thanks, I appreciate the compliments. Happy to answer any questions.

[@franprinsloo8885]

@@sjseth-builds Awsome thank you. I would really like to build something similar for myself. What exactly does the setting bump do? And does calibration work no matter the size disc ?

[@sjseth-builds]

@@franprinsloo8885 So bump is the little step back that the disk takes when it completes its movement. because the holes are so much bigger than the cartridge, it serves to stand them back up and also helps to move the disk away from the brass case in the annealing (flame) station so that the case can rotate freely without touching the disk. In regards to calibration, because of the placement of small rotating disk under the flame station and also the location of the feeding mechanism, the disk size has size has to remain constant. The hole size in the different disks can be different as long as the hole placement is the same (8 holes equally distanced)

[@sjseth-builds]

Also something to note: If the hole size is close to the cartridge size, you don't really need the bump at all. You can set it to zero. I made some adapters that fit in the holes and noticed that with them bump was no longer necessary (though I haven't yet worked out automatic feeding with the adapters)

[@franprinsloo8885]

@@sjseth-builds ahhh oke makes 100 % sense. Thank you . So if i make a disc with 10 holes I am going to have to change some of the code in arduino?

This is one of the better ones I have seen on YT... Could I buy one from you if possible? Thanks for sharing.

Looks like an Bench source annealer

[@sjseth-builds]

The bench source annealer is a beautiful machine! At the time when I made this, they were asking more than 1k for them and I just couldn't swing it. They have come down in price since then and I believe are in the $600 range which is still about 3x more than I spent in materials for this. I just don't anneal enough to warrant spending that kind of money!

[@michaelcurnutt]

Excellent work! I did have a question for you, what was the reason you added the bounce back, was it to help upright the smaller bass?

[@sjseth-builds]

Initially there were two reasons (1) Upright the brass, (2) remove the contact of the plate from the brass while it is under flame so it rotates freely. I later found that by using adapters to more closely fit the brass size, that the contact was a big deal but with the adapters I had to hand feed the brass. I need to redo the feed mechanism to work with the adaptors.

[@jesusisalive3227]

Very nice! How hard do you think it would be to use an induction heater instead of the torches?

[@sjseth-builds]

Probably not too difficult. You would have to build a mechanism to raise and lower the induction coil. You could probably use a long stroke linear solenoid to do that. Also induction coils get pretty hot so you need a way to cool them. Typically a fluid needs to be pumped through the coil. I did build an induction annealer for single pieces but had so many issues with it, I abandoned it.

[@DimaProk]

@@sjseth-builds Yes, I ran in to the same problem if you run it continually, I would recommend using timed relay, there so many of them out there but since you're using Arduino already you can implement that.

[@bumpitdown25]

How much is your investment vs. an AMP Annealer?

[@sjseth-builds]

I have around $220 into it in metal and electronics which includes tax/shipping. I already had the cerakote paint on hand so I didn't include that in the $220. The motor and controller together were about $50, power supply =$15, arduino mini pro = $7, wiring, screws, switches, connectors, encoder and screen were about $25. The metal is mostly 1/4" aluminum plate, some 1x1 square stock and some .5in rods, I figured the metal was about $120. Its hard to figure because I have a bunch of scrap aluminum, screws, wiring, etc. I would put a high estimate at $300 if you started empty handed. I am not sure how much an amp annealer costs but I am sure this was much cheaper last I checked. Also I think you have to single feed the amp annealer unless you add some robotic attachment which costs extra. My main goal was to be able to dump a batch of 200+ pieces of 5.56 or 308 brass in an let it run. Thanks for your questions!

[@WvMnts]

Selling them yet?

[@sjseth-builds]

Nope 😄 I have no plans to sell them. This was always a DIY project for me. There are already some really nice Annealing machines out there and the prices are coming down too.

[@jaythaler1704]

Would you happen to have a list of the components? I'm handy and would like to try this but I'm sure I'll get the wrong motor or something :)

[@sjseth-builds]

The whole machine is made from 1/4in aluminum. Other than the screws which are all m3, m4 and m5 of various head types, here is the main component list with links. A lot of these items can be bought in bulk to save money. Hope this helps and good luck! You should also check out my other video where I take it apart.
