ETMY Suspension rebuild status

More work on the ETMY suspension in BSC10 - this afternoon, Travis and I:

1) Hosted Barry Barish, Michael, and a film crew chamber-side for a filming project.

2) Added the balance of the sus payload to the cage - Sleeve structure, wedges, cross braces, vibration absorbers.

3) Installed the newest Bounce-Roll Dampers (BRDs) from Kissel (thanks!!).  This took a careful hand holding the bitty assembly with needle-nose pliers and inserting them into the mass before tightening with an allen key.  We also locked down the UIM and PUM since we were pushing on the UIM blades for this install.

4) unlocked masses, reset ETMY and TMSY watchdogs and turned damping on.

The alignment at first glance looks to still be on centerish.  More refinement to finish up tomorrow.
