 ====== Pendulum Clock Design ======
+This document is not completed yet, it is a work in progress with updates added as the build process progresses.
+The first part of the document discusses the design process and the second part [[04_projects:01_clock#parts_printing_and_assembly|the build process]].
+===== Background =====
 I saw some working 3D printed clocks and became fascinated with the idea and history of clock making. There are multiple publications of makes and 3D designs out there that can be downloaded and assembled, but they all lack the details that I wanted to understand and these are not described in the detail that I needed to understand. Also the terminology in horology literature is unfamiliar and now always clear.

   * A weighted driving mechanism with rewind capabilities, i.e. a ratchet
-I read entire books full of math and gear calculations without getting clear indications or drawings on how a practical friction clutch work or how to make one, or how to calculate and design a gear train and get the math to stack up but also then to get the gears aligned on once axis to indicate 60 minutes on the dial or 12 hours on the dial. This article aims to address all of that in clear detail.

 ===== Preparing the Gear Shafts =====
+The gear shafts are cut from any 4mm round rod material. I had some 4mm steel wire and searched for 4mm bearings to go with that.

+==== Installing gear shafts ====
+Once the shafts are cut to length and cleaned up, proceed to print the various gear assemblies and install the gear shafts by tapping gently with a hammer on a flat surface with a hole through and measure the shafts for the correct protrusion distances as shown below.
