TV Yoke - Simple Method For Removing Copper From Ferrite

**rca987** · 05-02-2013, 08:58 PM

Here is how I speed through my TV yokes. Typically I will break down yokes as I get them, and sort them into smaller piles.

Here is a tub of Ferrites with attached copper windings.

I hold the ferrite in my hand with the arch going away from my palm

I use 4 1/2'' Angle Grinder with a thin metal cutoff disc and cut across the arch making sure to cut though all of the strands.

And it peels off the ferrite very easily.

And this takes approx. 15 seconds per copper wound ferrite.
This is by far much easier than picking out the ferrite chunks after smashing them to bits.

That looks way more efficient than smashing the yoke. How many can you get through with one grinder wheel?

**rca987** · 05-02-2013, 09:09 PM

I typically will go through roughly 100 halves in a tub, and won't be at 50% disc yet.

Sooooo your holding it in your hand, without any gloves, running a grinder across it, that could cut your fingers off in 15 seconds?

If I am missing something, let me know here. But it seems to me, that one or the other, should be secured! It is way to easy, to lose a phlangie, in those 15 seconds!

jus my 5! an imma gunna keepem all

I do the smash and grab for therapeutic reasons but this could work.

**Sirscrapalot** · 05-03-2013, 04:16 AM

might be quicker and all that jazz, but like KZ said..I smash them for the therapeutic factor..something about smashing things is relaxing when your in this line of work..lol.

An just cause of the OP's avatar...I will end this post with...Lok'tar Ogar! My fellow gamers will understand...the rest..just chalk it up to my usual crazy self. :P

I also cut the windings across the outside & then peel the copper right off..... but I don't use no grinding wheel that close to either of the only two hands I'll ever have.

A bit slower, but (knock wood) still got all my fingers.

Carpenter by trade. The last thing you do at the end of the day is count to 10...if you can do that, it was a good day.

Correct. I am holding it in my hand, without any gloves. You can wear gloves if you feel it necessary. If you don't put pressure on your grinder and let the grinder do the work, you have a far better chance of not losing control of your machine. Also alot less wear and tear on your disc.

It is therapeutic but in the same light, how many other things do we already smash and bash with a variety of "weaponry"? Myself personally, I would rather take an 8 lb sledge or maul to a fridge for therapeutic reasons.

Zugzug!

I should have added that this is not for everyone, but it is the easiest way I have found to do it, and less time consuming. What is preached here so often is that 'Time is Money'.

thanks for posting the photos and your method. not saying I'm going to do it, but definitely appreciate seeing other methods & ideas

**Wolfwerx** · 05-03-2013, 09:11 AM

I more or less do mine the same way as the OP. Except I set the piece on my workbench rather than hold it in my hand. I do find it to be a very quick way to get this done.
The safety concerns are definitely valid, and should not be disregarded. I guess you could use some pliers or vice-grips to hang on to the ferrite rather than have your finger in there. The copper cuts so easily, if you don't mash down hard with your grinder it's a pretty smooth motion. Also, if you don't press down too hard when going through the copper, the cutting discs last for a very long time... try to just get the copper, and not dig into the ferrite too much.

Another bonus I've found by doing it this way: The yokes that have a ton of that epoxy/plastic all over them will sometimes peel off much easier off of the copper when you cut it this way, and you don't have to dig out little shards of glued-on ferrite.

I smash them, I'd never hold that in my hand like that and grind them - one slip and your hand is toast, what happened to advocating safety first???

**robsrecycling** · 05-03-2013, 10:06 AM

i use the grinder method as well but do it safer lol.i stick my grinder in a vise .then use a simple pair of plyers to grasp the yoke and slide it across

I like the concept. The only problem I could foresee is that if you tighten the vise too much, you damage the grinder, too loose and it vibrates out onto the floor.

**robsrecycling** · 05-03-2013, 10:52 AM

lol thats why i keep 2 grinders .1 is a dewalt but the one i use for this is a chicago electric i got new from harbor frieght for 14.99 lol.so if it does break or i smash it i dont lose much

BINGO!!!

The idea is a great one! And, now we have some good ideas, to apply it SAFELY!!!

With the kids skateboarding, I may try modifying the vice with some of their grip tape! I will also...HAVE MY SAFETY GLASSES ON AND GLOVES!

I am NOT shooting the idea down at all, RCA!!! But Julie is right! We need to promote SAFETY FIRST IN THE FORUM!!

Now ... where he heck did I put my reading glasses, need um ta find the safety glasses ;-)

**auminer** · 05-03-2013, 11:20 AM

Yeah, putting the ferrite in a vise could make this idea something I could get behind. Putting the grinder in the vise would work, too, but one slip & you could still get your hand cut.

I'm'a stick with the Wiss' tinsnips. Doesn't take long to cut the windings with those.

**freakinredneck** · 05-03-2013, 12:30 PM

i put yolks wraped in old cloths and smash with hammer unwrap and separate, quick way to go.

**ResourcefulRecycling** · 05-03-2013, 01:00 PM

Just sell them whole

**happyscraper** · 05-05-2013, 08:30 PM

Where is the safty in smashing ferrite, even if you wrape it in something you still have to pick all that sharp ferrite out from the copper. There are dangers in braking things down just be carefull while your doing it.
