I'm remaking an old automaton project from 2013 and changing the system to operate from a lever rather than a turn crank. In my pre-CNC days, all the parts were cut with the scroll saw or bandsaw, and I used to have to do significant fiddling to get my gears to mesh correctly. The CNC has eliminated all those problems, greatly simplifying the building process.

More as the project develops.

Can't wait to see the result. Now you're talking about kit making for science projects and educational thingies for kids who are potential engineers, demonstration devices for educators and on and on. Oh boy! more marketing opportunities for CNCers.

Looking at the top of the gear and the handle ,I’m amazed at the detail a cnc can do in the right hands .
Can‘t wait to see what the professor is scheming up next :)


is that 1/2” copper pipe your using for a pin, and is there a piece that sits on top of that copper pipe that it slides into also?

Yes, those are pieces of 1/2" copper pipe being used to test the gears. A 5/8" OD nylon bearing will fit into the gear shaft holes. The small gear will attach to a larger cam that needs to rotate only 158º.
