This afternoon we finished prepping MC1 and MC3 for the pump down scheduled for next week.  As per my prior alog list, we:

Tweeked the lower stage AOSEMs into place (Travis did the hard ones via YOGA moves across the table after I gave up).

Swapped the PFA EQ stops with the fluorel ones.

Installed the VAs.

Locked all the EQ stop nuts.

Add-on task - we dabbed a few particles off of the MC1/3 faces and then decided it was futile and will have to wait until the next vent for FC cleaning.  Note, while adjusting the AOSEM upside-down teensy set screws which are an inch away from the optic facees, we might have brushed a gloved knuckle against the MC1 AR optic.  Uugh.  Chalk that one up to an addition to a design change list or at least a lesson learnt.

Adding to the to-do/install list, Richard is also going to try to tackle the ground loop checks on HAM2/3 next week.

We'll also finish pump-prep work on the HAM3 SUSes (PR2 and MC2) next week.
