Fabricating multi tooth cycloidal cutters for clocks Part 2 “making the form tool radius“

In this video I show my process of grinding the radius for a form tool that I will use to shape a cutter blank in making a multi tooth cycloidal cutter. I will also describe the grinding attachment I made for my Schaublin 70 lathe. If you find the content helpful and informative for clock repair please give a thumbs up. I have other videos about making parts for clocks and there will be much more to come so please subscribe. I also have a discussion forum involving building clocks and making clock parts at You can find more at Thank you and have a great day. William
