I buy and break down mtrs. I pay $0.20lb for the mtrs mostly from my next door neighbor. Here's the numbers and photos of a single 90lb mtr I broke down. This is the single largest mtr I have done. Mike.
90lb @ $0.20 = $18.00
Break down results:
80lb #1 steel @ $0.14 = 11.20
9.28lb #2Cu @ $3.00 = 27.84
$27.84 + 11.20 = $39.04
$39.04 - 18.00 = $21.04
About 1/2 hr to dismantel although I didn't time it.

Now go beat the copper out of something, Miked
Nice Mike.I love them motors and the copper even more.I cut my ends off with saw zaw,i have a worry bout the grinder and breathing the dust from the cut.
Kbob, I agree on the dust. I've started working outdoors so much less dust in/on me and my shop. I like using the grinder because its much fater than the sawsall. I had to finish with the sawsall because this motor was too big for the 4 1/2" ginder. Mike.
That's what I'm running into as well. Time to up it to a 7 or 9 I am thinking.Originally Posted by miked

Beautiful, Mike. don't you just love the color of that copper after you cut it. I do it the same way...thanks to you and others who taught me. I always use my grinder....much faster and smoother, but I haven't had one that big yet. Thanks for posting this. It will help the noobs immensely.

if you are worried about dust you can buy a respirator with dust cartridges at HomeDepot for like 12 bucks wash it after each use and change out the cartridges every few days

I use an old tablesaw with a 10" cut off blade in it. Was always flexing and breaking the cut off blades when I used my grinder. Great set of pics! Were the end caps aluminum?

Was there still a tag on the motor, or do you know what the HP rating on it was?
No the end caps were steel. And there was a tiny amount of insulated wire not worth weighing. I think the percent of copper was lower on this than on most of the smaller motors I do. Also on many of the smaller motors the end caps are AL as Freonjoe referred to. I have considered using a table saw to cut the coil off. I am wondering what type blade you are using. I would guess a fine tooth plywood type blade.
If I were doing many of these large motors I would buy a bigger angle grinder as IdahoSrapper suggested.
I did it because we have a lot of new members and I find pictures answer a lot of questions. Thanks for looking, Mike.
Mike, I'm using a standard 10" chop saw blade. I get them at Lowes for 4.00 apiece. I can do 40 or 50 windings with each one. And I do use a mask and facw shield.
Out of curiosity is the shell, stator, and outer skin considered prepared steel or tin? I have been throwing it into the tin pile, but had a ephinany err brainfart. Gee I wonder if that is prepared? lol

On this one it would be #1 at my yard perhaps prepared at yours. Each seems to have their own standards. And those standards seem to change depending on how badly they need the steel. I am going to put this in a differnt pile than the scrap from computers and the like which is classified #2 at my yard. #1 pays 0.14/lb and #2 is .12/lb. Mike.
Mike, are you supposed to be lifting 90# motors?

You can also get a pack of those paper masks for cheap, least they keep the dust out,, DEE!! You don't even want a case of dust pneumonia. Or worse,,,if you are worried about dust you can buy a respirator with dust cartridges at HomeDepot for like 12 bucks wash it after each use and change out the cartridges every few days

Table saw with cut off blade is a great idea! I have an old craftsman table saw that would be perfect for that...

I find that for me a chopsaw works best on cutting the wire ends off. So far both cap ends of the motor have been i think cast aluminum. As for cutting the frame i use a plasma cutter at work.
I have sense went to a chop saw myself.Much quicker than my old method with my saw zaw.
