HAM 7 HEPI Install

Greg G., Hobo S.

HAM 7 now has the HEPI housings and crossbeams installed. Final positioning still needs to take place. I tried a different method of attaching the crossbeams; clamping them to the housings before fully setting the weight of the crossbeam onto the support tubes. When they are sighted in we'll see if this made a difference. Doing so seems to help keep the feet inside the housings more level.

Space was very limited in between HAMs 7 & 8 which led to me having to crawl under the chamber to reach all of the bolts. While there I encountered a friend (picture attached), however, we were in laser hazard and lacking proper safety glasses he had to be escorted out of the LVEA.
