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.
Great Instructables for building a wind generator:
Step 1: Aquire Materials
1 - 5/8" x 2ft threaded rod ($4.38)
2 - 1/4" x 3/4" hex bolts (for set screws) ($0.10 each)
1 - 5/8" Hex Nut ($0.33)
2 - 5.8" Cut Washers ($.31 each)
1 - 5/8" - 11 X 2-1/8" Rod Coupling Nut ($1.24)
1 - package of JB Weld ($4.97)
Grand Parts Total = ($11.74)
note: the JB weld and threaded rod can be used for multiple Arbors and numerous other applications so the real cost per arbor is approximately $3.10 USD
note: I used JB Weld to secure the rod to the connector nut because i do not own a welder and wanted to try and keep cost down, the stuff will hold like the dickens. If you have welding equipment, use that instead of the JB weld.
