Pre-pumpdown activities at Y-end
Removed iLIGO RGA hardware from BSC10 and installed 10" blank in its place*installed ESD interlock gauge and 4.5"-2.75" zero-length reducer on BSC10*Installed 2.5" aLIGO RGA isolation valve and 10"-4.5" zero-length reducer on BSC6 (remaining aLIGO RGA components to be installed later) 

"Bumped" dial indicator cluster on BSC10's NE support tube -> readings from these dial indicators can be considered "bogus" as a result 

Running QDP80 overnight but couldn't start Turbo pump as its foreline pirani gauge isn't working now(?) -> I'll fix this gauge tomorrow while rough pumping the Y-end with the QDP80.
