Here is a photo of a prototype Chiaphua motor mount. The dimensions are pretty simple:

Motor mount screws are 10-32, spaced exactly 2.00" apart
The center "bulge" is .75" in diameter
The centers of each gear (shaft, big gear) is .740" apart.

I mounted the cluster .75" from the center of the motor shaft and there is a bit of play. If/when I do this again, I will split the difference and mount the cluster .745" from the shaft.

This was all determined on my kitchen table with a caliper. I punched out the 1/4" plate with my milling machine (you need at least an accurate XY table) and press fit the 1/4" ground drill rod shaft.

What did you use to mount the shaft to the plate? (ie bearing or other) Also what is the final rpm coming out of this shaft? Is this close to the drill motors rpm?
Thanks
