besides scrapping it for the copper, is there anything else that can be done with these toroidal transformers? I got one from a friend, it's not huge, but it looks like something I would want to incorporate into a DIY build instead of scrap it.Originally Posted by jimicrk

That center piece will just hammer/push out....i have a pretty good system doing these

Yea the hammer you have in the pic probably won't do the job.........I picked up a big EASTWING roofing hammer in some scrap and it weighs probably 2 to 3 times what a normal cheap hammer weighs and has a longer "shaft" to give more leverage.........It is kinda awkward working in smaller spaces but for knocking the **** out of something it does the job.........If you could get it stood upright and braced properly a sledge might do the job...........Usually I cut away some of the exopy/glue before I go to hammering

ITT 601 KSU/1A2 phone system
I installed a phone system last week in an old building that was being remolded. This old phone system was mounted on a board in a back room and the GC said I could have it.
These systems were still being installed in 84 and I got to install a few of them. You gotta love the old technology. Each phone required a 25 pair cable!

So I have an hour and a half invested in the 15 inch transformer from the UPS above. My 3 pound hammer and about 20 whacks removed the center plug.
The first layer of plastic and copper have been removed. The bolt cutters help a lot.
I'm sure there are easier ways of doing this but I'm using what I have. I'll be getting 1 or 2 more of these soon and I was curious to see how much copper is in one.

Once i get it going I unwind it until the strand of copper gets to long then I cut and repeat

Obviously it will get faster the more you do but they can be time consuming

|
When i did ones similar it seemed to at least double the value of item as oppossed to selling it as is

It's been awhile since i did one. I can't remember if i broke it like you would a ferrite.
Nowadays i think i would cut it around the middle of the outside with a 4" angle grinder. The 1/16th inch thick metal cutting wheels work so well that i use them for a lot of things when i'm scrapping.

Yes Mike it did get faster this afternoon. I was able to finish removing the second layer of plastic and copper in 30 minutes. I haven't weighed the copper yet but the metal center was 80 pounds. I'm guessing 5 pounds for the center plug and the plastic wrappings so there should be 40 pounds of #2 copper. I have no idea how much copper is going for right now. It's been a while since I had any to sell.

Congrats looks great!

39.5 pounds of #2 copper in the first pic from the big round transformer above.
Since copper is up I decided to drag my horizontal band saw out and start cutting my transformers. I can set one up in the saws vise and work on other things while it's cutting. The second pic has some #1 I stripped and another bucket with about 50 pounds of #2 from transformers.

Heads up jimi, That should be bare bright not #1. Why down grade it after all that work stripping it, just remove the buss bar copper. that should be #1 or have its own category.
By the way i watched moose scrappers copper grading video LOLOLOLOLOL. Seriously i didnt but i had to say it
|

I'll check but I don't think the yards I go to have a bare bright category. I will be making some phone calls tomorrow. Thanks.
I second the use of an angle grinder, its a saws all for smaller jobs. 73 and thanks for sharing. Mike

Now go beat the copper out of something, Miked

I found 15 more toroidal transformers in a milk crate. They're a little bigger than a baseball. My plans were to cut it with my bandsaw, spread it apart with a crowbar and unwind the copper.
45 minutes laterI had 1 pound 9 ounces of copper and the core was 1 pound 12 ounces of laminated steel.
I will be going today to buy a few cutting wheels for my angle grinder and do what Hills suggested.

I finally got some cutting wheels for my angle grinder and cut the time down to about 8 minutes.

It is always when we need to use our angle grinder that we realize that it is our last disc and/or that we are out of spare ones. (I just had to go buy some this afternoon.)
