Starting the 1st version of the Motor Coupler4958 viewsHere we are starting work on the first version of the coupler to connect the 2 Impulse 9" motors.
This is going to be a single piece coupler that press-fits on both shafts.

Boring the hole in the motor coupler2634 viewsHere we are boring the hole for the motor shaft. 1/2 the hole has to be a larger diameter since it's coupling a tail shaft to a main shaft.

Finishing the coupler2570 viewsHere we are putting the step in one end of the coupler so it can fit down into the end-bell of the motor.

Finished Coupler3701 viewsThe finished coupler. (Well, I did have to have 2 keyways cut into it, and drill some holes for set screws after this.)

Starting the 2nd version of the Motor Coupler2507 viewsAfter our near-disaster with the 1st motor coupler, we decided to build the new one as a 2 piece unit. This will allow the motors to be separated if needed.

Boring coupler shaft holes2260 viewsThis time we wanted to be SURE our boring bar wouldn't flex, so we built a much stronger one.
We also are using much better cutting tips.

Shortening the coupler2241 viewsWe did start with a piece of shaft that was too long, and decided it would be easier to cut off the excess with a saw, rather than cutting it all away with the lathe.
