Yesterday, Travis and Bubba's crew landed on a new VEA cleanroom configuration that allowed for better fiber welding equipment layout. This involved moving the large install platform staircase out of the VEA and bringing down a slightly bigger 8x10' cleanroom. We had to fix some panels, and rearrange the laser safety panels, and then the cleaning crew cleaned everything this morning.
Today, Travis and I worked on moving the extracted ETMX lower QUAD unit to the chamberside staging cleanroom using the duct jack, separated the main and reaction chains, then mounted the main half on it's weld trolley. We removed all of the flags from PUM and UIM stages for safe keeping and re-install later. We rolled the main chain into the welding room and left the reaction chain to be reworked for the AERM install soon.
On another note, I reinspected the ETMX PUM mass which had a crack under one of it's prisms (FRS 4743) originating from the fiber welding many years ago - the good news is that the crack does not look any worse than it did in 2013, when comparing it now to pictures from then (see for yourself in the DCC link E1800076).
