Building a crusher for copper yokes? - Page 3

thanks for the lol's Hypo.....I especially liked the Lizard Lick Towing and Recovery !!!!! lol to tears !!!

Bobby's missing out with Big Juicy! (j.......k)

This might work and Scrapers sooner or later will find a dryer free to test , But i'll repeat if you really have 100'S of Crt to deal with ,put on some gloves , set up a drop cloth , a strong peace of wood to work on , & a rubber maillot you will be complete before you get this invention complete

I've heard that plastic in a dryer can start a fire. But if you got one to scrap that works run the 220 outside and see how it goes.

Or just unhook the heating element, some of them are just plugged in to the wiring. that way they'll rotate without heat.

Well holy crap. I know what i'm doing tomorrow. Buyin' myself an old cement mixer an puttin some magnets in it. That was the deal breaker at first when i saw the other guys post. But now that i got a better way to get the ferrite buildup takin care of, im ganna do it.

Thanks for the suggestion.

You'd just have to go in every so often to clean away the build-up.

I am going to try this. Next time I have a few, I am going to throw them in the freezer for a couple of hours. I am thinking that the glue will shatter just like the ferrite when tapped with a hammer.

You guys are seriously having a problem with the ferrite? Just a couple whacks with a regular hammer is all that it takes. The glue is the pain in the butt with them and takes way longer to seperate than the ferrite.

Now you have a use for all the super magnets out of the hard drives.

Yesterday I thought this was so easy and wondered why people with more experience than me were so concerned about these coils. This morning I open up a TV and the ferrite, glue, etc feels like it's been bloody welded on. It's a nightmare. Usually a quick crack with a hammer, the ferrite pops off and gets thrown right into a microwave box/scrap bin.this time, it's all splintering and breaking up into tiny peices, but remaining glued to the copper.

Oh well, you live and you learn!

don't think you'll see much success as glue seems kinda rubberize , last winter it was below zero so much , I sure loved how the cast metals cracked easier along with plastic but na that stubborn glue cold don't bother it. maybe 50 below zero ??
I use a mallot but when i get the glue type (since they don't all have it) i set aside for special handling , some times i'll get most of copper and put aside the small glue copper portion for special handling .

Thanks. I won't bother with that then. Sometimes it peels right off. Most of the time no.

I don't have any problems with the yoke really.
Smash it waith a hammer so the glass tube & clamps fall off, then stand it on end, point up, & bash it again & the thing separates & two of the coils fall out.

The two left have the 1/2 moon ferrite in them, thats the hard bit I guess.
I smash them but find the ferrite cuts into the Cu wire too much & makes separating them a pain.
Even after checking as I work I find little chips of ferrite.

My other two options are to cut thru the Cu coil on them & pull it off by using a knife or hacksaw.
Thats tough on the knife & potentially dangerous, even more dangerous if you are doing lots of them.

The hacksaw cuts the wires well but also grabs at the wires & makes a mess.

My best suggestion is to use a 4 inch angle grinder with a cutoff disc in it & a glove on my left hand....

I use the worn out 9 inch cutoff discs when they get down to 4 inch dia, after 5 inch dia they get inefficient in a 9 inch anyway.
Its all to do with the 'Feet per second' Not RPM.
