H2 HEPI Removal & Transport Fixturing Installation Progress

WP 8384 ScottL, ChrisS & HughR

With the HAM7 south Crossbeam out, 54633, we turned around, in a very small space, and extracted the HAM8 north Crossbeam today.  Maybe a little easier than the H7S xbeam but still a delicate threading between the Support tube ends, chamber bellows, SEI Expansion Bellows all while trying not to move the Support Tubes.  In the end it all worked and we managed to clean the space up even a bit.  Now ready for the Radius plates on HAM8 and the U-Channel and Radius Plates on HAM7.  Might manageall that next Tuesday but we need machine shop Tyler.  As a forecast though, HAM7 & 8 will be ready for Transport in three more Tuesdays.  Attached is the current state beteween HAMs 7 & 8.
