HAM3 Actuator Attachment Progress
HughR, GregG, JimW,

Today, finally, all vertical HEPI actuators were attached at HAM3. We will need verification from IAS, but at this point the position does not seem too terribly disturbed. Only a few thousands here and there based on what our dial indicators tell us. Most of the piers have very little room between the "back" side of the actuator and the pier (< 1mm), which will make things very, very messy if we need to re-locate the ground side of the actuators in the future (i.e. off-load the springs, shift the housings and then redo the alignment). Tomorrow, or whenever is convenient for One Arm people, we'll attempt to attach the horizontal actuators.
