Welcome to the 12th volume of Random Clock Talks! In this article, we will be discussing the art of making wheels and index plates for clocks using a custom attachment on the Unimat lathe. We will take a closer look at the tools and materials required for the process, as well as step-by-step instructions on how to create the perfect wheel.

Tools and Materials Required:
Before we dive into the process of making wheels and index plates, let’s take a look at the tools and materials required to get started.

  • Unimat lathe
  • Mainframe
  • Set of drawings
  • Index plate
  • Overshot spacer
  • Nut
  • Arbor
  • .8mm brass sheet
  • Backup plates

Step-by-Step Guide:
Making a wheel with 42 teeth, made of .8mm brass sheet, and about 1/32 of an inch thick requires specific steps and technique. Here’s how to do it:

  1. Attach the Arbor to the Unimat lathe: The Arbor used for making wheels is designed as a work Arbor to be caught in centers in the lathe.

  2. Use the indexing attachment: The indexing attachment consists of a mainframe, set of drawings, an index plate, an overshot spacer, and a nut to pull it up with a wrench.

  3. Create the index plate: The index plate is less than 2 inches in diameter and has 42 divisions stamped on it. It has an index pin with a precise fitting flat tip that exactly fills one of the slots in the index plate.

  4. Use backup plates: Backup plates are used to support the wheel blank while cutting.

  5. Mount the indexing pin: The indexing pin is mounted on a block that can be assembled on either side of the frame.

  6. Adjust the spring: The spring for the index pin is adjusted to enter straight into the edge notches in the index plate.

  7. Seat the index pin: The index pin is seated deeply in the plate to rotate it.

  8. Mount the mechanism: The mechanism can be mounted with either one or two screws.

  9. Move the spring: The spring can be moved to three positions along the axis.

  10. Watch and learn: A video on how to make the index plate is available.

After these steps, you can begin cutting the teeth of the wheel. The demonstration shows the making of a single wheel, but typically several wheels are stacked and cut at once.

Making wheels and index plates for clocks can be a challenging and precise process, but with the right tools and technique, it can be an incredibly satisfying endeavor. We hope this article has provided you with valuable insights into the process and has sparked your interest in the art of clock making. Happy tinkering!
