Mini Drill Press

Take two gears made ​​of wood, one rotational and one linear, allowing movement of the drill, which is attached to two drawer guides that give stability and rigidity.
The movement is executed with a lever that is connected to a return spring.
It's easy to do and can be very useful, such as working with printed circuit boards ....
The last two pictures are an image of the gears before I painted.

    While I'm sure it works fine, proper tooth shape for a rack is straight-sided at the pressure angle. To make generation of rack/pinion geometries easier, has a gear geometry calculator.

    This looks like a very useful tool. Can you provide an illustration and/or step-by-step with parts list so that I can better understand how you did it?
