I am looking to sell quantities of used refrigerator compressors for scrap

Actually I don't drill. I take a grinder cut an X into the top (highest part) then a chisel and hammer and tap inwards one of those corners created by the X. My Sims loves them that way and everybody wins.
I get 5 packs of grinder blades at harbor Freight for $4.99, sometimes cheaper with a coupon. I can cut about 15+ per blade. All considered incl the little extra cost and loss of weight from the oil I make pretty much exactly an extra buck each.
