With gearbox designs posted to CD in general there's often an overemphasis on lightening the plates as much as one possibly can, when it's really not that substantial of a weight savings over a more conservative lightening pattern or even unlightened plate.

Thanks for the feedback. Would you suggest that I cut back on the lightening holes, add some flanges, and/or thicken the plate?
