Today, Jeff, Andres and I finished disassembling the lower structure and 4 lowest masses from the ETMy QUAD upper structure.  This involved pulling all of the reaction lacing cables up the chain.  As well, we had to cut the fibers off of the previously monolithic HIFOy masses in the suspension.  When Travis went to cut the first fiber out, the lower mass was apparently under some small load and the fiber broke it and it's adjascent fiber off.  We think there was still some load on the fibers even though all of the masses had been locked in place.  We raised the test mass before proceeding to cut the next 2 fibers out.  Jeff, Andres and I then split the chains and left the main chain resting on the Genie arms and the reaction chain on the 5-axis/scissor lift equipment.

After lunch, Angus and I pulled the PUM out of the suspension and canned it (Gerardo - we're missing a top o-ring plate in the empty can - so the canned pUM is missing it.  We need to steal one from the next can out there).  I then cleaned the lower sus via vacuum while Angus continued preps with Travis in the weld area.  We then stuffed the new PUM and got practice fibers loaded into the practice suspension for welding tomorrow.

I'm now out the rest of the week, but here is the sequence of tasks that need to happen next:

TUE AM - Gerardo / Travis pull the Test Mass, park the Main in the weld room, park the Genie under the reaction chain for added safety

TUE mid-AM - Travis / Angus / Alastair start practice welding (make sure to get panels in place)

TUE mid-AM - TCS peeps swap the ring heater (yes, likely in laser hazard, sorry)

TUE aft - finish practice weld

TUE aft - Gerardo / one of the weld crew stuff the new test mass

WED - set LS main mass DOFs and start real welds

Y'all already have mad skills, so smooth running and good luck to you!
