Heavy Duty Transformers

[Copper Head]

Ok - First when you take apart a motor I have found it not worth dealing with the shaft in regard to the ones with the copper wound in like thread (thats the shaft) some shafts are steel & AL. regardless if it's the ones with the copper wound i sell them as copper bearing .25 or motors if the yard person lets it slide .50
Second it is understood the copper windings on the main housing are wedged a bit tight with plastic type sleeving as copper goes into steel ,Now that under stood
we are talking about a small amt of plastic.
Procedure
have a safe area ( A Pit) have some wood and cardboard available / now get the fire started, a nice good real fire,
once fire has calmed to ambers its time have a card board box on hand - fill the box with the housings and old news paper put box on ambers fire will do the rest a hot fire is needed for reduced smoke / if you see a bit too much smoke put some more card board on it, the extra flames tend to consume the smoke some what , if those housing get red they are clean , use a stick & pick them up and put in bucket of water (ice is no need ) just water . It's a learned balance to clean but to much heat also could ruin a batch. Any way this is hypothetical as you need to see about local laws.

I throw them in the woodstove. Pick them out with a piece of rebar and drop them in a bucket of water.
