Homemade Induction Annealer

[hdmunger]

Aluminum would be 1000% easier to work with LOL. The back side of the board does also allow you to quite easily have a shorter standoff, as well as easier to position a fan over the component side of the ZVS.

Here is an 'artists rendition' of how I set mine up:

 

[Bradv86]

I sure like the looks of this. My 1" copper flat bar has already shipped. I would ask though; did you thread the holes in the long block and use short screws to secure everything or did you bore a hole completely through both pieces and use longer bolts with nuts that pass through entire length?

I drilled and tapped everything, but if I was to do it again I would probably drill through fully. The center board screw I would still drill and tap.

I only have a drill press and Dremel, so going that deep in gummy material is difficult.

Pushing hundreds of amps through thin PCB traces does not seem ideal to me. I think this design from that thread I posted earlier is a good way to do it:

This is basically the same circuit as the chineez "ZVS" boards, but re-arranged such that, to the extent possible, the power components are cooled by water. For example, the capacitors are soldered directly to the copper pipe filled with water. There is also a fan blowing across them with a gap between to actually allow air to get through. It's nice that the fan doesn't blow smoke in your face as the powder residue/lube/whatever cooks off the brass.

Electrically not connected yet, have the basic machine sitting in top on my Dillon XL650.

Some items sourced used, or open box from e-bay. I have a buddy that's going to help me get the plug wired for the power supply, currently at a stopping point until after July 4th.

The plan is to universal deprime, and anneal on one pass (the first pass) before tumbling fired brass.

Guys... Years of discussions, 16 pages of comments and it exists this... Video on you tube on how it works paired with a timer switch. 200 bucks..

I have been using this for 3 years now. I have mine on a timer and rotated my coil so the cartriges can sit upright in a wood block (5 at a time). Much better than the hand torch method.

Hei... I have the same one but I can't get it to work with the timer... Mine is the model that once pluged, the fan starts and keeps on going non stop. If i wire the timer (intercepting the negativ) it doesn't do anything. The timer functions but has no effect on the annealing process. I still have to manul push the button and all..

Right. My fan run's continuously which it should ,to keep it cool. i have a 5 second delay between cases before the next heat cycle which i have to trigger for the heat. Depending on the case mfg either 3.5 seconds or 5 and the ambiant temp. All good

Can I ask you how exactly have you wired the timer? If it's not too much trouble can you send me some photo? I can't get it right... Thank you

This exact one? How much have you used it in the 3 years?

Maybe 4-500,, 22-250

There you go

 

[Sniper 78]

There you go

Thank you ok... So you connected the negative of the annealer to the negative from the socket ;the positive of the socket to the timer and the positive of the annealer to the timer right? What I don't understand is where have you connected the push button... You've said that the fan runs continuously like mine and the timer manages the annealing function intercepting the push button... How? Where did you go with the 2 push button wires?

Just hold the button on the unit and it will start when the timer activates the output. I have a 5 second off time to move to my next cartridge that is in my 5 station holder. Also I misspoke about the fan staying on all the time. It start s when the timer activates and you have to have the button pressed to anneal.

Thank you . I thought that you managed to wire the button directly into the timer so it wouldnt be necesary to hold it. I just bought mine and the fan keeps on going once plugged.. Maybe its the updated version... But did I understand corectly the wireing procedure? Negativ from socket to negativ annealer and positive from socket and positive annealer to timer? It's correct?

Just wire up a socket to the output side to plug your hot rod into and run hot and neutral to the input. Then program the controller.

Exactly my setup wooden board with holes in it. Tecnological as f**k . Works best for me. Wait... Your timer is powered via 220V? It's not DC 5-30 powered via dc adapter?

Yeah 120 not 220 . Mine is dc... I have to power it with an phone charger at 5 V

Yes. Different controller. I also give my hot rod a break after like 50 cases and just plug it it to constant power to let it cool down. Not sure on the duty cycle but why cook it.

I do the same pretty much. I don't think that it's a problem if used for more than 50 cases at a time but why risk it. On you tube they say that they use it with no problems for much longer but... I'm not a competitive shooter, I don't have to prepare 4-500 rounds at a time. I do 50-70 rounds than I give it a break

I'll FL size while it's cooling to use the time up.

What caliber are you doing and how much time are you using.

 

[LMTMWS]

Maybe open it up and wire to the red activation button so the fan remains running the whole time? I do t have one yet but I may try that.

 

[BrassWhole]

I could use a little word of encouragement. First off, I don't see how at this point in my build this would work. Looks like a direct short waiting to happen. I am trying to build this as a stand alone unit that will mount on top my Dillon XL650. It looks pretty, but in not convinced it will work as is. Here's a few pictures. Fans run constantly as I wired them separately in parallel to a USB. Well that's update from one month ago. Have not wired the timer, or DC power supply connections yet.

1. Copper coil very close to the tool head I had built for this project. Even then the aluminum plate everything is mounted to would need opened up in the area of the coil to keep a direct short from occurring with the nearby copper coil. Might have to go non-electrical conductive on that tool head. What do you think?

 

[swamper2]

I think a stand alone annealing proecess is what i would do.Less complicated than trying to intrigate into the dillon system.

 

[hdmunger]

What always strikes me when I look at your setup, is that the proximity of the coil to the large aluminum tool head might potentially cause issues with heat build up in the tool head itself (as well as excessively long heating times with the amount of energy being dumped into the tool head instead of just the brass case). I know aluminum is not a ferrite metal, but neither is brass and heating up the brass is the primary goal of this mechanism.

You mentioned maybe using a non-conductive tool head (3-D printed?) and that might be a solution...
