A significant roll of the ETM optic is apparent in the attached photos, which corresponds to the fibers breaking on one side of the optic. We used the welding mass jack to lift the mass off of the compressed viton EQ stops and to unload the remaining two fibers such that if they are compromised they would not catastrophically break. I would estimate that not more than 1-2 mm was required to fully unload and slacken the remaining fibers, indicating that they were already almost completely unloaded after the break.
The photo of the wipe shows a piece of metal particulate found on the lower structure and gives you an idea of the size and nature of particulate commonly found around the Quad as a result of the assembly/disassembly procedure.
