I think this would be the best method, with standoffs located at the 4 pre-made holes on the corners of the extrusion. Of course, the thickness of the standoffs may interfere with my next topic...

The ratios do not appear to be that much different from each other with this gearbox. I presume this is due to sizing restrictions? 2 methods to deal with this are:

1.) Increase the diameter of the driven low-speed gear, which would then require slots in the housing and thin standoffs or no standoffs from the assembly method above.
2.) Decrease the diameter of the driven high-speed gear, which may require yet another custom gear for the dog gear to mate to.

Which brings up the question -- what is the smallest size 20DP gear that can be pocketed out for mating with the dog gear?
