Leitz Optical Dividing Head Teardown P1

A slightly different video for you. We disassemble and study the internals of a high precision Ernst Leitz master optical dividing head. Originally used for metrology and inspection of gears and other circularly divided parts. This particular model can resolve divisions as small as arc seconds on the horizontal axis using a glass scale and elaborate optical system. Originally priced in 1951 dollars around $5225. This translates into roughly $52,000 in 2020 dollars. This instrument can also be used directly on machine tools for rotary indexing and rotary table machining operations. We open this unit up with a full Y incision and study some of the high precision opto-mechanical mechanisms and design features, albeit forensically. Unfortunately this video is really a machine autopsy. What would you call that? metopsy? Instropsy?
