Making spur gears using a dividing head | john f's workshop

Making spur gears. One of the most common ways of making spur gears is by using a dividing head on a milling machine. The dividing head makes it possible to cut a gear with almost any number of teeth. It is possible to use either a horizontal milling machine or a vertical milling machine. Either way the workpiece is held using a dividing head.
