 == Minutes and Action Items ==
 *Reviewed minutes of last meeting
-* We looked at Rory's pictures and discussed the 3D model that Stephanie shared
-* looking at space on platform, we decided to leave the vertical cable managers so we have some space margin in the future
-* Need to develop a dimensional layout of 3D model  --  Stephanie
-** Note: The chamber currently in the hall has different thickness dimensions than the new ones
-** New chambers are 2.09" thick skin to skin
-* Need to develop an installation procedure  -- Tim/Stephanie
-* Need to separate the 2 DS chambers for the electronics RF shielding
-** Rory to supply the gauge and dimensions of the shield
-** Stephanie to update geometry in 3D model
-* Floor rail system design needed to allow CPP to move along with the FCAl platform
-** Tim to supply sketch
-** Stephanie to create 3D model and drawings
-* Dark Room Structure
-** Tim to supply sketch for structural needs
-** Stephanie to update 3D model and create drawings
-** New structural members need to be installed before skin removal
-* Next meeting to be 1:30 to avert a time conflict
