Another thing - I don't really like the lightening pattern on the gear. The spokes don't do a ton for the gear's strength, and a spoked lightening pattern like that requires milling whereas a no-spoke lightening pattern could potentially be turned.

If you are going to do a spoked lightening pattern, at least make it six spokes and have the spokes align with the hex points. That way the additional material is behind the stress risers and not just in random places.

In either case, I would leave a bit more material around the hex (maybe .875 diameter?). The material left around the gear teeth should be fine. If the thin part of the gear is at least .15 thick or so you should be fine. These are "gut numbers" not backed up by real math or engineering, just experience, so take them with a grain of salt.
