So I pulled out the Dremel again and worked on the coupler. I Dremeled a section out of the clutch disk center piece and the motor's female piece so that I could use a key. The hub I am using for a coupler was made for a key. I also drilled and tapped two setscrews to hold the coupler onto the motor shaft. Lastly, I removed that useless bearing on the motor shaft female piece. I ordered an 11" disk of 1/2 inch aluminum from eBay (for $30!!!
)for the motor to sit on. I plan on purchasing 1/4 steel plate to make the adapter plate section that goes to the transmission. I might still use 1/2 inch aluminum for that if I can find it cheap enough.
