Atlas 10F Lathe - TH54 - 04 - Backgear Disassembly and Shim Calculation

In this video I discuss how the back gears are disassembled and the process I went through to determine what size shims I needed between the Head stock castings and the back gear castings to set the proper clearance for the gears. Please note that I made an error in how I performed this but later caught my mistake and corrected it. I will annotate the video where I goofed. I decided to leave it there because I am much less than perfect and am a neophyte hobby machinist.
