IAS has given me numbers. I am unable to move HEPI the requested amount (8mm -X) until the East side Caging Brace Front Faces are moved (removed). Hopefully we'll be able to reinstall these which allows the HEPI to be locked. Once this is done we can attempt the translation East. I believe there is room otherwise for this move. Caveat: The Actuators are not attached; they have interferences that are not directly determinable now. For the record, contrary to many statements from SEI to date, BSC1 has only been marginally locked if it can be said it was locked at all. Most lock bolts were not engaged and only a few of the 40 were doing anything.
Correction: The error is in the -Y direction, not -X.
