Holy smokes, I guess I have a bad eye for spotting car batteries.

$450... Bought a bunch of ac compressors for cheap and cut them open with a grinder. Each one had a 40lbs plus electric motor inside and a little copper tubing. Load was somewhere around 1500lbs. The pics of the load are on my business facebook page at http://www.facebook.com/twofatguyswithatruck
I tried to cut the enameled copper out of the motors, but after the first one took me over 2 hours, I called it quits on that idea. I had 25 compressors to go through. Probably would've taken me a week for an extra 60-70 bucks.
I'll beat this eventually.
Cut the top off with a angle grinder & cut off disc.
Cut the wires inside that run from the motor to the outside of the can.
Pull the motor out & unscrew anything you can see.
Get the anglegrinder again & cut thru the copper wires where they emerge out of the top of the motor.
They will come off in bundles of 1/2 loops, with string holding them together, just to annoy you.
Now make a bonfire & chuck the motor on it so it burns off all of the varnish & insulation.
Now let it cool down & pick the long motor windings out.
Done.
First, with the varnish & crap there, it holds the copper wires together & makes cutting easyer, its also work hardened copper wire at the moment.
Second, after burning the varnish off, theres a lot less to hold the wires inside the motor & now the wires are 'annealed' & soft & it makes it easy to pick them out.
I did this last week & thought.
"Hell, nobody else does this, I can make some real $$$ outta the copper (3Kg? copper wire) & then sell the iron as its heavy"
The only down point was the oil... It ran everywhere around the shed. Congealed all of the dirt into oily gritty mud.
