OK - you could argue that I am just having fun with my new bellows - seeing how small a part I can effectively shoot. And, hey, you would probably be right. But, this shot really does make a point. Each of these teeth are roughly 12 thousandths of an inch wide. Note that the rim of the gear is roughly the same width. And, as can be seen, the width varies, exactly as you would expect for a piece made by hand by a journey man in the shop of one of Vienna's great makers. Telling too are how perfectly each tooth is made, taking into account the wear that is evident on the left side of each tooth. When you look at the shots of the gears between the plates - realize just how extremely finely made the gears really are. But also, realize how very little inertia there is for the train each time it initiates a strike sequence!
