DIY Induction Annealing Brass with .01 second accuracy for $200

I'll show you how to build your own Induction Annealer for brass cases that is accurate down to the 1/100th of a second and so powerful it can anneal a case in under a second. You only need the 5 items listed below. The part 2 video is now out to address all the design questions and some tips I've picked up over the last 2 years of using this setup.
Induction Bolt Heater Found on Amazon here, They have raised the price since I made the video but I have found some cheaper alternatives.

These are the links to the original heater in the video
amzn.to/3IxArQu
amzn.to/2XWXq5W
So many of you have put this together Amazon is now suggesting these items together with the relay timer.
The relay timer here says 220v but this is the same one I got. I believe it is "up to" 220V. If you need something more solid try the next link to an alternative timer.

amzn.to/3EQlpV2
3-Prong Extension Cord

Also, check out this Labradar Recoil-Activated Trigger I developed. It has an intigrated pic rail attachment and magnetic mount. It can also be left on your rifle full-time with the detachable cable.

[@jimpolicke7639]

I got this heater and timer and it works GREAT!! I used a Berry’s bullet box (slightly larger) and the 9V power transformer fits inside. Instead of the loop in the power cord I cut off the end completely, and use the plug end to power the transformer. All fits in the box, so all I have coming out is the cord going to the outlet and a short stubby cable to plug in the annealer. Very consistent annealing. I run the annealer 2.7 seconds for .223 brass with a 6 second off cycle. Instead of making my own coil I took the smallest coil included and just twisted the coil a little tighter for a closer fit. But, thanks for making this video! I’d still be thinking about how I was going to start annealing my brass without it!

[@user-kz2hu4wi2x]

Greetings, I constructed an annealer assembly using your idea with a similar unit but added a couple of convenience refinements. In lieu of using the push button all the time I installed a 3.5mm phono jack and plug. The jack receptacle is installed at the rear of the annealer and wired in parallel and soldered to the push button pins. The male plug is wired to the dry contacts of the timer so that when the dry contacts of the timer close it acts the same as pushing the button thus turning on the annealer. This allows the annealer to be used for other purposes and not dedicated to servicing brass. An on/off toggle switch was also installed on the cover of the timer case and wired in series with the “hot” conductor of the power cord so the timer can be turned off and on rather than having to unplug the timer from the power strip each time. The annealing unit came wired so the fan stays on all the time. On other units where the fan only comes on when the button is pushed the fan can be rewired to the annealer input power wires so that the fan stays on all the time. I have not had the annealer overheat as yet even when annealing a couple of hundred cases at a time. I found that using #10 AWG solid wire took too long to heat up and cool down. I made some coils with #12 AWG solid wire and they seem to work better, reducing heating and cooling times. All in all everything works quite well and I believe is much safer than the propane torch or hot lead immersion methods. Good luck.

[@Rico11b]

This is awesome. Thanks for sharing. It does appear though that it's heating the case to far down. Also another idea is to take what you've built and put it in a case. The with a perfectly aligned hole in the top just drop the brass in head down and wait for it to kick on and off, then just keep repeating. At that point it would be a matter of how fast you can remove one brass and insert another one. And since it will align perfectly you won't have to worry if the brass is touching the coil once you drop it in.

[@johnschiffermuller4930]

Outstanding. Works just like you say. I set mine up next to a single stage LEE Challenger and changed out the switch for the inductor so that I don't have to hold the button down. Control is through the relay with a locking on/off on the inductor. I raise the brass into the inductor coil and use a longer gap between cycles to give me time to swap the cases in the shell holder. I'm using it to anneal 24ga Magtec shotgun brass to form .577/450 Martini-Henry cases. Once I got the time dialed in I haven't ruined a case since, forming in 3 steps and annealing between each step. I'm not doing hundreds of cases (generally a box of 25), so the longer time isn't a big deal and the fan keeps up with the temperature well.

I saw no reason to post a copy of work you’ve already done. Have recommended the setup to others as well. I DID get an aluminum block and had it CNC’d for 7mag cases. That eliminates the issue of overheating a plastic reloading tray. It was also cheaper and I had access to someone who did that free. This is the cheapest setup of all my reloading “toys”. Great concept and kudo’s to posting this.

I knew I was in the right place when you broke out the Berger bullet box. 😉

[@markpawlowski8631]

I took your ideafurther by adding an ice cube relay to send power to initiate a signal to trigger theswitch. Ifound the annealer needs to run constantly to cool. In short, 2 cords from the same circuit,one to the controller, and one to the annealler. A cord from the controller goes to a coil that pushes the button, so the internal fan runs constantly.

I just finished my build too with some improvement. I disassembled induction heater and jumped out 2 button wires and 2 12v fan wires by an old 4 wire usb cord. The fan wires connect directly to the dc power supply and button wires to the relay terminals. Then I put 12v power supply into the same control box. This way the fan is always on when plugged in and only a low voltage control signal goes through the relay.

[@northeasttexastactical351]

That sounds clean!

[@benhil8861]

Thank you for this video. I just built this setup but put it in a box with a trapdoor. Mounted the hot rod in the box on all thread with hanger strap. Sloted the holes and added knobs so you can adjust your coil up and down. The all thread lets you adjust the left,right. If you pop the back off of the timer you'll see a connector labeled trigger. I soldered wires to the gnd and low signal terminals and ran them to a momentary pushbutton on the front of the box for a start pushbutton instead of using the one on the front of the timer. I'm using a 15a 24vdc power supply to feed the timer, solenoid, and some cooling fans. I ganged up two computer turbo looking fans to force air into the back of the hot rod so it has a continuous air flow instead of only running it's internal fan when the timer turns it on. There's a pretty good breeze coming out of the front of the hot rod. I have a timer relay that will auto activate the trapdoor with the annealer finishes. Getting the cases out of the coil asap may lessen the heat soaking into the coil. My first coil attempt was 12awg wrapped 7 times around a 10mm socket. It would do a 308 in 4 seconds. The second was 8 wraps around a 308 case for 556. It turns the case red in 1.5 seconds. I think I'll do a different .308 coil with 8 wraps around a 338L case to get more efficiency. Thank you NETT for this vid and your updates!

Slow heating is not a bad thing - it give you finer control over the result. Also, don't forget to cut the coil wire as short as possible, like in the video - it helps a lot.

[@johnhagerman1465]

Great system. I used 8 gage copper wire and made my own coils by wrapping it around some tubing. I started with 5/8" I.D., and it took 9.5 seconds to get the .556 brass to glow. I then made another coil with a 1/2" I.D., and the heating time really decreased - 2.5 seconds to get the same glow. So by decreasing the I.D. by 1/8", the time to heat was about 1/4 of the time. BTW, I also saw that the 110-volt timers listed on Amazon don't go less than 1 second, so the 12-volt timer was necessary.

[@northeasttexastactical351]

Good info, thanks!

[@tyler6147]

@John Hagerman I built mine using the 110V timer. It skips having to use a secondary plug and cable to run the setup which for me is a big plus. I am more than pleased so far. I just got it completed yesterday. That said the wiring of the 110V unit was a PITA. It took a while because the instructions are worthless. I got it now though and it's fine. Anyway this is the first I've seen anyone explaining the difference between the 12V vs 100V timers. Really though asking out of curiosity more than anything would being able to time below 1 second make a difference? I could easily convert mine for $12 but at first glance I don't see the need.

[@johnhagerman1465]

@@tyler6147 Actually I originally built it with the 120v unit before I found out it didn't do less than 1 second intervals, so I switched to the 12 volt. In my limited experience so far, I think the 1 second interval would be workable if the induction coil I.D. is larger, like I originally had with the 5/8" I.D. coil. Certainly using the smaller coil means that the timing is more critical due to the fast temperature rise - maybe that's not such a good thing. By making your own coils and experimenting with I.D. sizes, an operator could probably come up with a happy medium pretty quickly.

I’m doing this for annealing

[@G5Hohn]

Put mine together last night and with the way my coil is wound, I'm not sure I'm going to mess with the timer. I don't think it matters how far down the case your anneal goes as long as the neck and shoulder are fully annealed. (obviously you don't want to soften the case head or web). I just wound the coils using the coil winding mandrels that come with my Socket Set (8mm and 9mm mandrel as you did-- worked great!). It seems plenty effective to just heat until you see the first hint of glow, then release.

[@G5Hohn]

Funny that I’d get a notification of ETT liking my comment the same day I finished the timer build. It works great! My particular coil needs 1.4 seconds for a good anneal, but I’m pleased.

[@countercivilization]

Thank you for the tip! I was looking at the different annealing process and machins... all very pricy often bulky, complex and for some dangerous (who wants molten sodium on his bench or carbon monoxid in the room...) Your solution is the way to go for me! Thanks again :)

[@ls2005019227]

This is one of the best annealing videos on KZbin (I've watched/re-watched several times), thanks! I recently purchased the induction heater and a timer. One wrinkle though: while the heater looks identical, the interior fan runs constantly (which is probably good for cooling) once plugged in. I hesitate to disable this by using the timer to control power to the unit....but don't have a lot of great options. I'm not really interested in changing the internal wiring to exclusively power the heater from the timer..... I guess another option would be going the route of removing the case out the bottom, as the GinaErik design does- Any thoughts or wisdom would be appreciated. Thanks again for the cost effective idea!

[@northeasttexastactical351]

Glad you liked it. Ive seen guys who get the one with the fan on full time. Regardless, the induction unit will only have power when the relay allows it, so technically it shouldn't matter how the fan operates when plugged in normally because they will all operate the same when using the timer module. The only difference I see is when you aren't pushing the button the fan will still cycle on and off for the set amount of time due to the relay.

[@ericstrabel4365]

One work-around you can do is to have a short 'off' phase that is just long enough to transition onto or off of a case. Then hold the coil well above during 1-2 cycles without pressing the button that powers the coil so that the fan runs but the inductor does not. You could also just keep another fan blowing nearby, like the creator of this mentioned is good to do anyways.

Technically all the coil 'turn' counts should be in 1/2 turn increments. When you make a full turn, the end wire is pointing in the wrong direction. You need both leads pointing in the same direction so you can attach them to the power source (heater). This is why the directions for making inductors by wrapping wire around a drill bit references 3.5 or 5.5 turns.

Gotta love that phrase, "Technically speaking", always comes from a "certain" kind of person 🤣🤣🤣

Worked with industrial induction heaters in the past. They kept the coils cool by making them from small dimension rectangular copper tubing and pumping distilled water through through it while it’s running. The wires are connected to each end of the coil and it’s electrically just like you have on your setup. Pure water is a pretty good insulator, and using about 8-10” of small diameter rubber tubing at each end of the tube turns the water in the tube into a long resistor with a low cross sectional area and therefore a high resistance. I remember seeing wires connected to a water cooling system totally blew my mind until I figured out how it worked…. Once a tube sprung a leak and a maintenance man simply shortened the hose to quickly get it back in service. He equipment didn’t work correctly and because we were not aware of the hose repair it took a while to figure out what the problem was.. I’ve got about a years worth of brass before I need to think about annealing, maybe I’ll set something up on my Dillon 650. It would be pretty easy.

Finished putting the pieces of mine together today. Disassembled the heater so I’m using the time to just control the switch. The fan runs continuously on the heater and it stays nice and cool. 1.5 on and 4 seconds off is just right for the coil I made to use on 38 special brass. I ordered some 3mm fiberglass braiding with my timer and used 8 gauge copper for my coil. Stayed nice and cool

Love my AMP Annealer, it is a precision piece of equipment. You get what you pay for!

[@northeasttexastactical351]

You sure do, and the other $1000 goes into AMP's pockets.

[@Bushmasterpilot]

@@northeasttexastactical351 you have no idea what goes into building it, plus your setup might work for you, but for guys like me that load 30 plus calibers its way simpler than your hokie setup!😉

[@Quicks1lvr]

@@northeasttexastactical351 show us how to make our own suppressors, so we don't have to give those companies $700 for $100 in parts. Help out the people

hahaha, epic reply@@northeasttexastactical351

@@Bushmasterpilot right! btw they are called cartridges

I would imagine the 27 thumb downs were the product manufacturers that are pissed you made something better for way less and more consistency. getting the parts now thanks.

[@northeasttexastactical351]

All 27 AMP owners..

I'm curious how much power (ex. how many amps) the device is drawing during the annealing cycle. I'm assuming the open circuit voltage on the output (where the induction coils connect) is a nominal 120 V.

I'm looking at the AC relay that is the second of the two links above. I'm not sure how to wire it. Can I power the timer relay by tapping into the hot (feed) side and jumping to the + on the relay power? Then where would I ground? This would avoid the extra DC cord and clean up the unit.

I ordered the parts from Amazon, and the last one came today. Quick and easy setup, and works exactly as described here. Great video and thanks for producing it. The only change I see so far that I need to make is to attach the bullet box to a thick steel plate, because right now the box is much lighter than the cord and the weight of the cord pulls it off the bench.

[@northeasttexastactical351]

That's true, my box just flips around on the table. Glad you like it

[@nt_wicked_bunch2717]

Pretty cool video, I just built a “bench source” style annealer a couple weeks ago and I am very interested in building an induction style. I work with automations so I’m gonna have to come up with a way to automate the process.

[@WvMnts]

Any luck?

Hello Mr North. Just question for you or others reading. I bought everything and it works AWESOME. However, the induction heater I have works with the fan on all the time even when you don't press the red button. This is good to save the machine as you mentioned. However, when I put it on the timer relay the fan only works when the button is pressed. I think the relay cuts all the power off the heater. Is there a way to adjust the relay so that it still powers the fan ??? Or the work I did with the relay is just a continuous stop watch. PLS HELP!

[@mrgruisinge]

Good for you. I am doing something about the same. I use copper tube and pump water through it. Never gets hot. Use a computer water cooling radaitor and fan.

[@northeasttexastactical351]

I thought about upgrading to something like that, but it only takes 1 second, or actually like .92 seconds to anneal a case, so I can do 100 cases in about 6-7 minutes with a 3 second off cycle
