Vintage Sears Kenmore Roll-A-Matic Reversible Box Fan Model 480-81810

Picked up this heavy-duty, vintage 3-speed electrically reversible box fan via Facebook Marketplace. The motor was in incredible shape, but the original steel spider propeller was slightly out of track. In this video, I will show the custom-riveted blade set I used to fix the balance, and test its unbelievable more-than-one-minute coast-down time.
