We're stacking two per "gear" for all places these are used.

I actually used the formulas out of the Machinery Handbook to generate the curves. In hindsight, we made gears with teeth that were way too detailed. The specific waterjet our sponsor uses hesitates slightly before moving to each new curve, so the teeth had much more material blown out than if we had used a simpler tooth model (which would technically be less accurate, but would survive the cutting process better). We learned our lesson for next time here, but even with that flaw the gears still roll smooth on each other.
