The gearboxes for 267 were designed setting the gear center distances to line on line for pitch diameter. The drills and all the purchased gears worked fine with a tiny bit of backlash. The FP motors (used by themselves) however needed to have the center distances openned up I'd say .005 to .010. I never was able to figure if this was a manufacturing problem but this happened with 2 set of parts so I suspect not. Just something to be aware off. Next year I'll accept some additional lash and make the design a little less sensitive.
