Electric motors

He heated em' up and then dropped them into a bucket of water. They were much more cooperative after getting " The Treatment " !

I was banging away on those strings that hold the copper windings together this evening. The hammer worked well enough but then it dawned on me to use the hatchet. The hatchet worked even better. It cut those strings and broke up the varnish like nobody's business.

Hm I have a hatchet thing someone. Made out of a tire iron lol. I sharpened it sort of lol. I mite try that. Or heat them up haha I will keep you posted on the results.

It's been a few weeks Mike. How are things going ?

Whew ... it seems like there's been an ungodly amount of work to be done on this end lately. I'll be glad when things finally settle down for the winter. The Christmas holidays make for enormous amounts of material entering the waste stream. Not many air conditioners this time of year though .....

Been pretty busy got all my rads done from the last of the acs 37 of them I have 37 compressors to cut open to get 74lbs of copper out of them the strings on those just pull off haha. The yard I go to says I have to take all the strings off or they will give me electric motor price if I wanted that I would have left the motor whole haha. My blade should go through the compressors providing I don't snap it off at the base haha. Looking to try a cold chisel for the motors to get one end off not sure if it will work or not going to try it on one motor and see first have to get a cold chisel. The hand made tool didn't work so well for the wires it does however work for the rivets on the 9 lb motors I have 84 of them down to just the copper middle part each one is 5lb then 2lb of copper out of them when I'm done I should have close to 300lbs of num 2 copper. I'm getting there slowly but surely.
