Since the grinder was not successful, I borrowed a plasma cutter from a friend of mine. Upon getting home I discovered the pug on the plasma cutter is not compatible with the 220 dryer outlet. I run to home depot in to buy an adapter, I do not find any.....so I bought a new outlet that will work with the plasma cutter. You have to cut the back of the coil buckets to remove them from the axle. There was a half inch of weld I could not get to. After a half an hour of prying the weld gave and the bucket broke free.
