[Jeff, Daniel]
We attached the 10 in CF Flange to Rotatable 8 in CF Flange 12 in long Custom Nipple onto the Laser Filter Cavity (LFC) Output Vacuum Cube. When dropping in the copper gasket, we used 12-14 bottom bolts instead of the usual 4 because the nipple applied a large torque pulling the top away from the cube. Otherwise, we installed it as usual and I tightened the bolts to 34 Nm.
