With my help, Ed & Zach of Apollo, installed and attached the HEPI Actuators on WHAM2.  We did have a few mechanical issues as the positioning of the chamber (and hence the Support Tubes and HEPI Housings) drifted from the Initial alignment baseline.  We had to increase the size of a few slots to allow travel of connecting components.  Still all attached and it appears we have no motion issues.   We'll see for sure when we make range of travel measurements after the HEPI plumbing has us back operating.
