I cleaned the top of the IFO Vacuum Cube and added a 10" to 6" CF Zero Length Reducer Flange. I then added a 6" CF 6 way cross (with a rotatable flange face down). I tightened the bolts so that the copper flange wasn't visible and there was steel to steel contact all around.

I moved a bunch of vacuum equipment from B150 to B111B for the igo cube: A 2.75" CF Tee, 4 way cross, angle valve, all metal angle valve, pressure gauge (down to ~1 mTorr) two 6" CF Gate valves, a small ion pump, and an ion pump controller. A bunch of other equipment was attached to what we needed, including two 8" to 6" CF reducer tees, 6" CF tubes, additional 2.75" angle valves.

I also moved an all metal angle valve into B111A for the RbQ chamber.
