This morning, Travis, Mark D and I mated the ETMX lower QUAD to the install arm/elevator which is attached to the chamber door (see renderings in E1100832 BSC Arm user guide if interested).  We then made the final structure disconnections between the lower and upper QUAD structures and then pushed and rotated the lower unit out of the chamber.  The ACB was swung back for this (using the wedge), however the TMS was not.  Like at EY last month, the elevator is able to just slide in and rotate around the QUAD which sits sandwiched between the ACB adn TMS.  As is the typical sequence, we then used the blue Genie duct jack to pluck the lower unit off of the arm/elevator and place it onto a LSAT (lower structure assembly tooling) cradle and trolley (picture attached of final placement for the day).

This afternoon, Travis and I got the AERM out of it's air bake oven (epoxy curing air-baked last Fri), put it in it's cake tin, and took it to the end station for install.

We then started rearranging the furniture in the cleanroom area designated for the fiber welding scheduled to start next week.  However after shuffling things many times, we are still struggling to work out how to make safe maneuvers with fragile fibers in this space.  (Every weld cleanroom ends up being configured differently because each time we're in a different area with different room parameters - the hidden "beauty" of mobile fiber welding.  In the current case, we are using part of a big cleanroom which has the beam tube, VE and OPLEV equipment running through it, with a joining smaller ~10' cleanroom attached.)  We aborted the effort at the end of the day with no great solution - Travis will get with Bubba in the morning to see if another round of CR shuffles will help.
