Upper Body In Place
Setting the upper body carefully on the base. The next step of re-inserting the thrust bearing to capture the unit ended up being the hardest part of the whole process. The tolerance to the center shaft was so tight that the bearing tended to bind with only a mm or so of engagement when not perfectly aligned. This resulted in having to remove the entire assembly multiple times to use the scope to pop of the bound bearing. In the process, the new bearings were upset at least once and had to be re-worked. ARGH! Eventually it went on correctly and I was able to complete assembly.
