i'm about to fill my war chest (literally) and scrapping some old electric motors; there's a heap of pure copper inside, but it needs some experience to crack them.

The copper price is right now abnormally high, probably totally unrelated to global events...
Dunno if any scrapheads are on the fediverse, if not, I'm the first i guess.
Anyways, if you're interested I show how to dismantle them (my way, with my tools)

#Scrap #Metal #Copper #Recyclingthe aluminum hull is easily cracked either with an angle grinder or brute force; aluminum breaks more likely than bending.
Al has a decent price per kilo, but because it's so lightweight, one needs a lot. The main price stays the copper.

First I cut of the loops on one side of the frame. I'll clean them later.
I used to use the angle grinder for it but the heat sometimes makes plastics glue the copper together, which makes it harder to remove later. So I went for the muscle-driven metal saw.

With a lever, strong screwdriver, or a longer metal if necessary, I pull the wires out of the generator block. In this case the copper came out very easy.

After one side is out, I wrap the wire around a strong metal to yank out the other half of the loop, running back to the other side

Ok, the core is emptied. The rest is iron, which isn't worth that much. No need to remove the plastic bits, that will happen in professional facilities with machines and methods I can only dream of.

Wanted to do a smaller one for relaxation. Disappointingly, the wire is only copper-coated aluminum here. Not worth the work to strip down totally, I take off what's easy, the rest goes to mixed scrap.

This one I fucked up when I didn't know what I was doing; by cutting the core frame I also cut most of the loops, which makes it very hard to get a long enough end to pull. And this wires are also full of glue, which doesn't help at all.
Let's see what I can do to rescue the harvest...

Let's see what I can do to rescue the harvest...Today's harvest. The bucket weighs around 20 kg now (dunno in stones, ounces or teaspoons), maybe 150-ish €.
The stuff on the table needs final cleaning but not today.

Uh, my box with 'worthy' cables. These days I'll strip them and show my cable stripping machine (Yes, gimme all jokes including a stripping machine, pls)
