While what you describe certainly could be done by someone with very steady hands, good eyesight, and great attention to detail, I would argue that any team which only has a drill press shouldn't be considering building custom gearboxes given the plethora of great COTS options available.
Much more valuable to expend that effort on other areas of the robot.
