Drawing Gears with a Compass (simplified method)

Please turn on the captions for extra instructions! Hi everyone, I wanted to make a video about drawing out functional gears with a compass. It goes over the basics of reference diameters and modules, but please keep in mind that it is a simplified method (specifically one that doesn’t use any software or power tools). If you’re looking for a video that goes over pressure angle and profile shifting, there are other videos out there that cover it. Additional Notes: - Some definitions: the module is the size of the tooth, the reference circle is where the spacing equals the tooth thickness, the root circle is basically the gear without its teeth, the tip circle is the gear without its spaces, and the center distance is the distance between the centers of the gears. module = m tooth number = z reference diameter = d root diameter = df tip diameter = da - Everything is measured in millimeters in this video - Some common modules to choose are: 1, 1.
