We found we were really pushing it with the strength of the hex shaft, and especially the holding power of the two #10 screws. If you've got such a big reduction, consider engineering it to use another output and mounting arrangement to bolt directly to frame members and/or sprocket bolt circles.

There are two separate designs. This one is a larger, higher reduction gearbox meant for moving large arms at a 900:1 ratio off a miniCIM or CIM. The other one (CGX-116) is a VP stage with a lower reduction of 594:1, but can only output to a hex shaft.
I'm seriously considering designing a better VP output stage or output shaft that can hold a larger shaft and maybe output to a 1.875" hole pattern. I totally agree that the mounting options and hex shaft are limiting factors here.
