I have an old Shepard Lathe that I am working on. It did not come with a thread dial and never had one. I found a gear from a treadmill height adjustment that meshes with the lead screw perfectly. I intend to use it to make the dial. Fabbing it up should not be an issue.
The problem I have will be setting the graduation marks on the dial. The gear has 10 teeth. Every dial I've used is divisible by 4. I have no idea how I would go about setting this up.
What procedure should I use to mark off the dial to ensure it is accurate.
