Followup... this works beautifully. I was a little worried at a few stages of
construction when the 1x4 brick sometimes would rotate until it wasn't engaging
either gear and then sit there with the 8t gears spinning freely- but in the
full assembly it's quite reliable.
My whole rig came together very nicely in ~4 hours, with this problem as one
small piece of the puzzle. Now I probably need to spend about another 8 hours
making it run more smoothly and 8 more to make it look nice.
The details of this project are under wraps until NWBC, but I'll be sure to post
it here afterwards.
Thanks again, David!
