HAM2 Doors are Removed

(Jordan, Travis, Randy, Mitchell, Gerardo)

The +Y and -Y doors are off HAM2. The removal of the doors was made easy by removing most of the bolts the prior day by Travis and myself.
    + Y Door we had both O-rings get stuck to the door, we used the O-ring tools to set the O-ring back into their groove without problems.  No further issues.
    - Y Door had similar issues as the +Y door, when the door separated from the HAM chamber the O-rings were stuck to the door, same fix as the other door.  Something to note, this door's chamber flange has lots of oxide residue on the outside of the outer O-ring, as if it was sprayed heavily with alcohol.

To be able to remove the doors for this chamber as well as HAM1, both chambers are under the same cleanroom, we need to shift the cleanroom along the Y axis to accommodate the forklift mast height when removing the doors, any door.  Maybe this cleanroom should get longer legs and maybe that way keep a permanent position.

A big "thank you" to those that helped move the cleanroom.
