My Dad was an electrical engineer for Rea Magnet Wire in Fort Wayne, Indiana. I’m pretty sure he would have had great interest in what you are doing! As a kid in the 60’s I remember seeing the machines draw copper wire through various size dies and then applying the insulating lacquer coating which BTW had a very distinct odor. Anyone who worked there or went by the plant in Fort Wayne knows the smell. Keep up the good work!

I had heard a guy could rewind things, now I understand a little about it. Another good job by you guys.

[@SuperMAZ007]

That was time well spent, now you can fix all the crappy Eismann magnetos out there.

[@lifeafterourloss]

Very true, 😂.

[@TJAkin]

Very enlightening for all of us with old magnetos. Thanks.

[@tmscheum]

Good stuff! Feed the algorithm. Grow the channel. Keep ‘em comin’.

[@TomTeater]

Fun to watch, really!

[@lifeafterourloss]

Thanks as always Tom. 👍

[@rodneymiddleton9624]

You did a great job!!!!! Thanks!!!

[@wilmamcdermott3065]

Lots of good information

[@lifeafterourloss]

We put it to use on the hit and miss engine magneto. It really made a hot Spark! Thanks for watching.

[@Papa-vq3fv]

New territory on an old subject very good content gentlemen. Thankyou

[@carlthor91]

There is a Swede on YT who made a charger for magneto magnets. He works with really old stuff. Looks like you have success going.👍 Best wishes and a Happy New Year to all.

[@lifeafterourloss]

Thanks. Happy new year to you as well!

[@YesterdaysMachinery]

Old stuff is the best! /Richard

[@chincha805]

that was cool. i learn something new everyday, thanks

[@briankennedy5578]

Should give us a look at that nice looking Bronco in the background.👍

[@lifeafterourloss]

I can get it out one of these days. 😊

[@Fatamus]

Not many guys know how to recharge a magneto magnet. You guys are my heroes.👍😁 Happy New Year’s 🎊 🎉

[@lifeafterourloss]

Thanks Dan great to hear from you. You have a happy New Year as well!

[@jefflee1467]

Great episode. Have a good new year. Thanks.

[@lifeafterourloss]

Happy New Year to you as well!

Center drill,

[@bigredc222]

Very interesting.

[@brianforson2630]

That was very neat thanks for showing that on the video

Hello gentlemen thanks for sharing your knowledge I found it very enlightening and I don’t know anything about this subject so my question is what would happen if you left the battery charging on your coils for let’s say one minute instead of 4 seconds is there a risk of blowing up the battery? Wouldn’t that charge up the magnet stronger? I ask because I think a lot of cranes had a set up like you built and they would flip a switch to turn on the magnet pick up scrap metal and then release the charge and the scrap iron would fall into the shredder and I didn’t think there was any danger in leaving it on to long but I am no expert just wondering how it works and what is exactly happening when you connect it to the battery? Happy new year everyone 😀🇨🇦

[@lifeafterourloss]

If you leave it hooked up too long it will create a lot of heat through the magnetic energy. Similar to an induction stove. So you could potentially get the battery or the coils extremely hot and possibly catch fire. My understanding is a small charges all that is really necessary. A lot of the scrap yards do use electromagnets. But they are more of a continuous system with an alternator with industrial wiring and coils that can take the continuous voltage. The principal is exactly the same. The separate coils hooked up to an electric source create a magnetic field. When you bridge it with a piece of metal or magnet it completes the circuit of sorts of the magnetic field. That's my basic understanding of how it works. I could be completely wrong. Happy New Year to you as well.

[@keithwarkentin]

Thanks 😀🇨🇦

[@matkremzar5474]

Never let go of chuck key big no no.. that drill is called a center drill. 1.5 times thread diam.min max strength .

[@lifeafterourloss]

Will remember that thanks for the advice. 👍

[@jimkurk5575]

about how many feet of wire did you use? can you put more windings on than what you did?

[@lifeafterourloss]

If I remember correctly I used 150' per side. You can put as mary windings as you want. Ours turned out to be fine with what we did. Hope this helps. 👍

[@jimkurk5575]

this may be stupid question but do you have to have same number of wraps on each magnet/each side?

[@lifeafterourloss]

Not exactly, but I would keep them as close as possible in length.

[@dansshop]

Anyone making one of these, I'd research a bit further. What's here may work (or it may not work as well as it could, we don't know if that magnet is fully charged). If I were to go to the trouble I'd start with low carbon soft steel (not axle shaft), I'd do a little research about ampere turns (you probably want about 30,000 or more), the size of the cores etc. And it depends on the material the magnet is made of. For the time and cost a little more study should go into it in my opinion. Perhaps in this video they've studied what other folks have done more than just appearance. I'm planning to build one so I've been reading and watching some.

[@lifeafterourloss]

Greatly appreciate your opinion and advice. Please check out part 2 of our hit and miss engine magneto rebuild to see the results of a charged magnet from this tool build. 👍
