Almost destroyed my motor, trying to get the fracking pulley on the shaft with key. Finally got the pulley off, and had to reassemble the motor and clean etc, to get it to turn like the other side. Took me an hour and a half, to grind down the key to fit. I am about to go out of my mind, I had to leave all my tools at my previous place, and havent been able to get past covid restrictions. A toolmaker without tools, is a miserable wretch. ARGHHHHHHHHHHHHHHHHHHHHH.
Only hammerlike thing I had, was a meat tenderizer hammer that weighed zilch. Destroyed it.
