I think I'd rather have the second machine. It splits the windings, then presses them out. No cutting. As it is I have copper dust and stray windings all over the place.

ha ha!
I like the second one best.
To cool.

Can't be in the U.S. not nearly enough safety equipment. Even in the 60's we had to use two hands to start a machine in the factory I worked in. The two hand start buttons ensured that you could not start the machine with one hand in the machine. Mike

Now go beat the copper out of something, Miked
I saw one that was much quicker (ie not as much fiddling) as the 2nd video on youtube somewhere....it used a similar hydraulic press to cut them in half and then a claw mechanism to grab and pull the copper out....you didn't have to adjust the 'clamp" for different sizes...it did it automatically...
PROFIT is made when you BUY/ACQUIRE NOT when you sell
Question is how many motors would you have to scrap before you could afford one of those guys. The second one is definitely the smart way to go, but then you have to get two machines instead of one.

Oh Lord, yes. I wonder how many fingers and thumbs are considered 'fluff'?
So I cut out a lot of electric motors like most folks here. If you are able to get the windings out.. does your buyer pay you any better for just the windings with the core inside the wire?
So nutshell: I get .20/lb for a motor
For the windings full.. I get "Uhh how much would we pay him for this?" "Well if he bashed out all the magnet.. he could get copper price"
I got so frustrated with bashing my brains out trying to get the windings for someone to go "uhhhhhhhh" I always leave em whole now. Has always bugged me as I know there is far more profit there breaking them down!
I'm so into scrapping.. When my Steel Toe Boots Wear out, I cut the Steel out of them and recycle the Toe!
Seems like a log splitter with a modified blade would work. They can be very dangerous if not used safely. You just need enough motors to justify the expense.

So the log splitter idea is a good one. But that is only the first part. It looks like they just squeeze the wires together and lift the magnets out. I am sure doing the second part by hand would still be easier than trying to break those magnets off the motor.
I use a logsplitter to pull copper only. I cut one end off with a chopsaw. Have done hundreds this way.
Got a reply. It ships out of Korea. Cost is $18,500. Wasn't clear if that included freight.
I would think you could homebrew one for a lot less than that. Mike
The second phase in the last video kind of look like a tire changer with a modified head/turntable.
I could probably build the second one...but I also use a chop saw to nub off one end then pull all the windings through or push the stubborn ones with a punch and hammer... tedious and only do it when i dont have e scrap to do.
It WOULD allow you to chase the bigger motors that have many pounds of copper in them. Those are the ones where the windings are vacuum impregnated with varnish and are darn near impossible to get out with only hand tools. The rewind shops burn them clean before removing the wire.
