When I did mine I didn't have my lathe. Used my mill and rotary table and did lots of passes, round and round. Is really smooth. Now I have a nice lathe, could easily do an 8 inch chunk of aluminum. As far as the coupler, taper locks are nice but instead I did a simple coupler, .0015" undersize. Made everything just right ready to assemble. Heated the coupler in the grill as hot as I could get it, guessing about 500 degrees. Grabbed it with a pair of channel locks, slipped it all together and bolted it up. Worked well. Not sure what I would have done if it cooled too soon and weren't all the way on. Not sure what I will do to get it apart if needed. Might be what the saws all is for. Hope not to need to find out.

Use a taper lock shaft coupler. Use a motor clamp shell with a platform base or build your own motor mounting. Position two motors on a thick aluminum mounting plate not less than 3/4 inch thick and not less than grade 80 hardness or use 1/2 inch chrome moly steel plate. Do not bolt the motors in place yet. Couple the motors together and position the motors on the base plate. Use a feeler gage to see is the motor platforms are touching the base plate. Check any gaps with a feeler gage and adjust the motor plate by loosening and re-tightening the mounting bolts. All my shaft connections are by the Dodge Power Transmission Company or call Dodge PT components. Many machine shops handle Dodge PT or Browning components.
