Here is one other approach to a clutch for the x table drive- using a floating gear:
I followed the thread of
mrjbinok- because this gear drive is "less wide" than a direct drive with Z crank handle and motor drive shaft face to face.

The support frame was cut and machined for a nice square fit. Notice that there is a 1/8" lip on the end pieces to make it easy to align for welding.
Mock up with the support taped together.
After welding assembly is started.
Original crank is removed.
12 volt power supply is mounted to the wall abd motor assembly is trial fit on the mill.
I decided on a spring loaded momentary ON-OFF-ON rotary switch and picked up a perfect box from Amazon. I wanted the box to mount at an angle so used a couple of cabinet hinges to mount. Later I locked the hinge in this position and used JB Weld to make it somewhat permanent.
My unit has the DRO monitor right in the way, and its pretty crowded space up there and hard to reach.....
Want sort of same thing on the x drive system, with the motor as close to the table as possible . The floating clutch gear in the utube video seems easy to use, but not sure if plastic gears will hold up...
