As for beveling the teeth, why would you dremel each one as opposed to chucking it up in a lathe and filing it or even making a light cut?

I'd have to make a drawing to show you what I'm talking about, I think. Lathing the gear would get you something looking exactly like if you'd done the same thing with a rod or other cylinder. I'm talking about beveling each individual edge of each tooth.

The point of this is to reduce the cross-section that has to mesh. If you bevel both gears, then it's pretty must the exact same cross section that has to mesh and line up. If you bevel each edge like I'm talking about, then initially it's like meshing two gears with much smaller teeth with lots of space between them.
