EY QUAD disassembly started

This morning Travis and I went into BSC10 (EY), swung back the ACB to gain space around the ETMY QUAD structure, and started the disassembly of the QUAD - removing QTY 4 VA's, cross braces, Sleeve wedges, and started on some of the sleeve fasteners.  We then did a fit-check to see if we could get the install arm elevator into place without having to also swing back the TMS.  We didn't get the sleeve removed but it looks like we'll be able to get the elevator in the spaces around the QUAD structure without having to pull the TMS back.  We'll try next ~Tues-Wed and see how far we get.

(Note, swinging back the TMS involves a lengthy process of adding support brackets and equipment to the TMS lower table section, loosening some of the suspended cable sections, stopping up the upper mass, then pulling it back for a few extra inches of clearance.  Resetting it all after the maneuver is complete will result in a many day period of realignment of the TMS.)
