During the recent switch from the Spieker chamber to the original Yale chamber, there was some basic confusion about how to re-install the Yale chamber. Most involved agreed that it would be useful to develop a checklist for chamber swaps. I offer the following notes as a starting place for this and other procedures associated w/ the SPS.

The following notes are lessons learned (or more accurately re-learned) during the recent chamber swap.

# The overhead gantry cranes can not center over the target chamber. In the past we have slung a 1 ton chain hoist over the gantry crane bridge as close to center as possible. It is not perfect and two people are required to control the chamber during hoisting operations.
# The clamp ring bolts that hold the chamber down to the trunnion at the bottom are metric M8 - 1.25 x 25mm.

I believe the pin enters the section of the chamber that rotates w/ the trunnion, but this should be confirmed before leaving the pin engaged.
