Making Clock Gear Cutters part 1

In this very informative first video of a multi video series William Porter touches on some simple cycloid tooth form theory as well as some homemade tooling he constructed for making clock gear cutters.

This first video covers:

Making clock gear cutters part 1 is a is a great introduction into the fascinating field of horological gear cutting.

If you enjoyed this video please go to Williams YouTube channel at Fabricating multi tooth cycloidal cutters for clocks. Part 1 and give him a thumbs up and maybe post a comment and definitely Subscribe to his channel as he has been putting a new video up every few days and they are all very informative.

  1. Hello Mr. Porter,

    Your clock repair videos are excellent. Thank you for mentioning my Clock & Watch Makers Guide To Gear Making, and The Pin-Pallet Escapement, adjustment and repair books. The non-relieved, highly polished, burnishing gear cutters work harden and smooth the surface of the gear tooth, and take less time to make than form relieved cutters., and work quite well as you have shown in your videos.

    I have just published a new booklet, Radial Flank Angles & Sines, which is a companion booklet to Guide To Gear Making. This booklet is a list of the radial flank angles for over 150 gears listed in the Guide To Gear Making, as well as the sine value for each angle, and the “X” dimension (inch & metric) for the three inch (76.20 mm) sine bar to make gear cutters. All your sine bar calculations are done for you. You are also shown how to calculate the radial flank angle for several types of gears without using trigonometry.

    There are four different gear tooth width factors used in the Guide To Gear Making, depending on the type of gear, and number of teeth in the gear. The radial flank angle, and the “X” sine bar dimension, can differ for gear teeth using the same module and number of teeth because of the different tooth width factors. Examples are given in this new Radial Flank Angles & Sines booklet.

    Best regards,

    Robert Porter

    1. Thank you Robert, I have thoroughly enjoyed learning from you, your book, on making multi toothed cutters. I have been extremely busy even from the time I did the last video on the subject and I regret not finishing up with a final video. Since then I have made several cutters for successful restoration projects and a couple for the clock I am attempting to finish building (I guess paying the bills is important too).

      I am sure your new booklet would be an excellent tool to have on hand along with your Guide To Gear Making. Bob and I would be interested in purchasing one.

      If you could provide us a link here in the comments (The system doesn’t normally allow links to be posted but Bob has just cleared that for you) to purchase your new booklet then everyone here can see it and benefit from you knowledge.

      Have a fantastic day, William

      1. William,

        Thank you for your interest – The Radial Flank Angles & Sines booklet is currently available from Timesavers, Collector Bookstore, and Cunruh Books. Others may carry it later, as it was just published in April, 2018.

        Keep up the good work, you are helping a lot of folks learn the art of horology.
