Ah- yes the mental picture popped into place. Knurling is really REALLY simple (and pretty cool). It could be something you guys experiment with now, especially since you already have the lathe, etc.

The gearbox plate looks good. I assume bearings will be pressed into it. I'd be curious to see what results you get as far as the tolerance on the press fit from a waterjet. We've had access to a waterjet for a while, and we use it for a lot of things. One thing I've always been wary about is bearing holes though. We usually will cut out almost the entire part and then go back to correct the bearing holes with a secondary process.
