Making Parts To Connect The Orrery Gear Train

Now that the gears for the Orrery are made we must determine the center-to-center distance between them in order to get a good mesh with a minimum amount of friction. There are formulas available to calculate these distances, but they are theoretical. The method shown in the next video results in very accurate measurements.
