I recently wired up my father's older Rockwell 2 HP Unisaw, circa 1980 (?) to use in my basement, for some cabinets I'm building for myself. Ran fine for a couple dozen cuts and then ceased to work. There is juice to the saw but the blade does not turn, just sort of idles there, humming and ultimately trips the breaker. I've seen some other similar posts but wondered if there is anything unique to this saw I should know about? I gave everything a good douche with the air and tried it again, also found a loose wire in the back but still nothing at this point. Thanks.
