Is there an easy way to break this down for recycling? Answered

This is a new feather in my recycling cap.  Is there a way to break these down. I'd like to get a better price than "electric motor weight". Thanks

LOL , the easiest way I've found is to take a portaband " handheld portable band-saw " and just made one or two cuts all the way though it to let the copper "fall " out . I don't if you have one but I imagine you could find a used one fairly cheap .

I used to carefully tap out one of the iron ( I ) pieces of the stacked EI sections.
Some xfmr manufacturers make this easier by stacking two or more EIs
together.
After getting some iron ( I ) sections out  then tap out an ( E ) by the center.

Yes..... its tough work and you will bend a few laminations, sharp chisels,
knives and fingers.  But It gets easier as you go, and that feeling when you pull the last iron lamination out is really worth it.
Now you pull tape off the bobin and harvest the fine copper primary windings by counting or weighing it later.
And harvest the secondary by unwinding and counting turns from the plastic/ nylon bobbin..

Why do this ??
Aren't we going to wind our own xfmr reusing the bobbin and basing our design ref on the data we took ?? !!!

Your lucky it's not welded like this Horror :-)

Don't have a clue for you if your cap is anything like the one I harvested.
It says  0.77uF @ 2100 Working VAC and on the next line is printed,
INTERNAL RESISTOR  that limits the cap to that specific application only.

well i dont have any intentions of building microwave any time soon, so im assuming the capacitor is pretty useless for me, isnt it?

Only if built in resistor it has.

If you burn it in a fire it will get rid of any the paper and glue and varnish and plastic. The copper should then be easy to remove. It will also melt the solder away so any connections will be undone.

Use a drill to bore out the copper windings - collect the cuttings, then scrap the iron.
