How to cut and smooth gear and clock wheel teeth: In this video I cover the how & why from start to finish. Scroll saw blade used, blade tension, blade breakage, safety, how to cut the pattern, sanding/filing and the particular scroll saw filing strips I use, are all covered. This is how I have cut and smoothed all my wood gears... planetary gear drive, clock wheels, pin gear ring gear (in part), clock winder and the marble machine.
