H2 BSC8 ACB De-Install

Tim N., Gerardo M., Bob A., Thomas V.

Today we assembled the support table (D1101953) with lab jacks and brought down the box portion of the Arm Cavity Baffle.  Since we were waiting for a few tooling parts to be baked (they did not fit in the bake oven on Friday), we will assemble the installation lift stand (D1101957) tomorrow in order to bring down the suspension portion of the ACB.  

Both the suspension and the box portion will be laid down in the tube while the cartridge is being removed, then the suspension and box will be extracted afterwards.

Also, we dropped a 1/4 wrench on the BSC floor plates and it slipped underneath into the bottom of the chamber, we were not able to reach it.
