The attached gear was pocketed on each side .112, leaving a web thickness of .150.

That is a 7075-T6 gear isn't it?

Andymark sell a few gears with weight saving holes in, I think in the weight saving your not going to be able to reduce enough weight to make it equal to an un-weight saved Aluminium gear however it would still be great to do some experimentation

Team 254 did some really nice weight saving for the large VEXpro aluminium first stage gear in their CIM-over wheel gearbox, I'm not sure if they had any problems with any gears during the season.

We probably don't want to hi-jack the thread with a Aluminium gear vs steel gear debate

Is the slot to prevent the gear from resonating?
