WHAM6 HEPI Actuator attachment progress
This morning I reattached the V4 Actuator for the fourth time biasing the Crossbeam 30mils high.  This time the beam was pulled down 45 mils.  Ah geez... While I have resisted doing this in the past, this time I decided to just pulled the beam back up with the DSCW HEPI Springs.  I do this with trepidation cause I'm not sure how this might affect the other corners.  Still, it may make sense.  The attachment of the Actuator imparts a load and why not have the Springs carry this?  OK more Actuators after the SEI Weekly meeting.
