A possible solution for making gears for low speed applications would
be laminating with rivets, screws etc. several thin gears machined
out of sheet metal. The X and Y milling coordinates would generate
the profile of the teeth around the periphery. The thin sheet metal
would allow use of a small enough endmill diameter for a given tooth
pitch as well as the keyslot. Machinery's Handbook should give tooth
profiles which can be
circular arrayed in a CAD program and dxf'd out for G-coding.
