It's been a few months since I posted but I'm still at it. I had a service ticket today and me and a coworker had to install a new battery backup and remove the old one. I got to keep the old one. The pic below is the one we removed and the customer has 3 more they will be replacing in the next two months that are much bigger. I'm guessing the one below is around 1200 pounds.

I wanted to share some more pics of the UPS above. The top part had a 15 inch toroidal transformer and was super heavy. The next cabinet down contained all of the big power boards and the other 6 were full of batteries. 112 pounds of batteries in each of the 6 cabinets. They're not hard to take apart, just a lot of heavy lifting. I'm going to start checking around on battery prices but most places are usually .20 a pound.
I took apart a big one similar in weight to this one. I had sooooo little to do I disassembled all the coils and windings to get the #2 cu out. I don't recommend doing that. 73, thanks for sharing, Mike

Now go beat the copper out of something, Miked

Mike I've taken some smaller ones apart before but didn't get much copper out of them. I just weighed this one and it's 125 pounds and the center is filled with epoxy? Not sure but it would have to go in order to get to the copper. I might save it for a rainy day.Originally Posted by miked

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

I might have to get my BFH out!

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.

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

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 second the use of an angle grinder, its a saws all for smaller jobs. 73 and thanks for sharing. Mike

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 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.
