GQuEST Optics Tables Moved into Place

[Jeff, Sander, Alex, Daniel]

We raised the screws holding the breadboard connecting the two optics tables and raised the optics tables up onto thier wheels. We then moved the tables 1' North so that the pump out station would not conflict with the wall. We moved the tables as West as possible so that the vacuum beam tubes won't hit the door frame but not so far West that the mobile clean rooms can't fit around them in their final configuration. We ensured the optics table was parallel with the West wall.

We then lowered the tables. The joint between the two tables is not level, so we will need to shim the legs (or replace the bottom of the legs). Ideally, the tables are in the same plane and all the legs make contact with the tables to prevent any rocking modes. Rigidly connecting the tables seems to remove most of these rocking modes. The gap between the table and legs is smaller than in the previous configuration.
