  Update: report from the owner of the rotator to say the pinion and shaft are working well. Looks like I didn't screw up! Yay!

  For &quot;normal&quot; gears, it is quite easy to determine Module from a physical gear: M = OD / (N+2).<br>OD = the outer diameter of the wheel, N the number of teeth.<br>So, with an outer diameter of 7.0mm and 12 teeth, you do indeed get a Module 0.5.<br><br>To go from Module to pitch, you multiply with PI, so the teeth in this gear should be spaced 1.57 mm apart.

  The Terry Pratchett reference just further cements my idea that you&apos;re an excellent fellow! The greater the odds, the greater the glory!

  Nicely done! I am a bit surprised you didn&apos;t go all out and build a stepper motor indexer just to make the tiny pinion though ;)

  A lot of work goes into making a single gear but it&apos;s enjoyable to watch and you get better at it the more you do it

  So convoluted! Excellent video. I learned so much, and not so convoluted!

  AndysMachines has an excellent &quot;How to identify unknown gears?&quot; video here on Youtube. Also lots of videos on gearmaking, and making tools to make gears (he makes his own gear hobs, made a gear shaper, shows how to make gears with a slitting saw, etc).

  Extra points for the Pratchet reference!

  I find it strange that you don&apos;t have more followers. The production value is top notch, and the humour is on par with This old tony. I rather like the self deprecating aspect of it. <br>Greetings from the Netherlands

  Congrats on your first gear. I made my first gear a few days ago. What a satisfying feeling, especially for some 60 year-old worn out equipment. Cheers.
