After Reading over numerous instructables about wind generators and failing to find a
motor arbor at any of my local hardware stores i decided to make my own. I did find several online, however they were much more expensive than I expected, and the cheaper ones looked fairly flimsy. While looking for the arbor, and getting mostly blank and confused looks from employees at Lowes, Home Depot, Harbor Freight, and several smaller auto repair and supply shops I noticed a Rod Coupling Nut of the correct diameter for my motor shaft (5/8") and the plan came together. This is how I constructed my motor arbor for a 5/8" motor shaft. These plans can be adapted for any sized motor.
