Some guys use a machete or a meat cleaver to split their electric motors apart. Machetes and meat cleavers are kinds of knives too. They slice through.
Yea that's what someone also said. Id say I like my SDS er drill not the fastest thing I found out going through the copper is a bit faster. I have 76 small ac fan motors to do half have a plastic tape that's a pain to try and get off the other half have a paper stuff and 5 are bare with no paper so the paper and bare ones I can do faster the plastic tape ones not so sure. In any case I still have a er drill that I can use to do other stuff besides scrap since I'm on the last of the AC stuff now also have brass from relays not sure how much I'll get out of that I have a 5gal and a partial full of them. I'll report back on those when I'm done. It's been a interesting journey. It's sad how the forum has kinda went down a slope since I joined it was vibrant not many of us left I suppose I have used the hammer drill to split motors in half to works good if you can get in-between the plates I found it easier to cut the copper crown with the hammer drill I can do that in 3 minutes so that's pretty cool. My knees lock up sometimes haha it sucks being 36 yrs old haha. Comes with scraping I suppose. You can even use the hammer drill on the brass weights on the bottoms of the window ac compressors I have 4 lbs from 35 compressors some had a top and bottom brass some on had the bottom ones. Some have steel that sucks when that happens.
