Go to Post We also have a CNC mill and CNC lathe, but we're interested in doing this only if we can do it quickly. Milling anything takes too long for my MTV-generation attention span. :) - Madison [more]

The motor will stall long before the plastic gear strips, and then you let the magic smoke out and that lovely burnt motor smell fills the air.
Correct me if I'm wrong, but I seem to recall that FP motors had face mounted vent holes, so an improvement to this gearbox design could be to add openings in the plate to allow air to flow through. (unless you have them and I just didn't notice them in the picture, in which case, props to you)
