What is the C-Face rabbit? It looks like I would have to cut two
rabbits. One approx 1.5" in diameter where the output shaft is, then a
groove approx 1/4" wide that is perhaps 3, 3.5" in diameter. (didn't
measure it yet).

Do have have to cut those rabbits?

It is the projection used as a guide when you install the motor on
something like a right angle gear box.

Syicks out from the face about 1/8" and from memory is probably about
3-1/2" dia

You have a standard NEMA 56, C-Face motor.

I have used a couple of them for tool drives.

The easiest way is to use a piece of 13 ply, 3/4" plywood as a mount.

Drill clearance holes for the four (4) mounting bolts and cut out the
hole for the C-Face rabbit to fit.

Mount with bolts and fender washers.

Use LocTite on the mounting bolt threads.

After that, there are several ways to mount the assembly to provide belt
adjustment and maintain belt tension.

The simplest way is to provide a hinge mounted flat base the the motor
mount ply can be attached to and use the weight of the motor to maintain
belt tension.

The above is exactly what I did to power a small, 4" Rockwell jointer.
