The interesting thing is that for conventionally made gears, you only need one hobb per pitch. All gears of a given pitch can be made from a single hobb, which is fairly straight forward to design. One instance where the old way might really be easier.

Could you please explain to me (or show a picture) of what the involute surface and hobb is? Thanks.
