I one by one took out the 12 point hex screws that secured the custom base of the Laser Filter Cavity (LFC) Cube and inserted and moderately tightened nickel coated hex screws, with a smaller screw head heights, and washers. I then did this process for the 12 point hex screws that directly secured the Tapped 10" Flange and added washers. I then tightened the screws in a star pattern until I could no longer see the copper gasket. See attached photos.

To put the cube on the base, we lifted from the same 2 lifting points in this post. The cube naturally tilts such that the base goes down furthest when lowered again.

We lifted the 2nd LFC Cube in the same way as the first and repeated the same process. This time, I used torque wrenches to tighten the screws, incrementing by 4-5 Nm every time. The ultimate tightness needed to no longer see the copper gasket was 33 Nm. I recommend going by more than 4-5 Nm becuase it adds more opportunity to strip a screw. I nearly stripped one, but was able to tighten it to 30 Nm. We then put the cube on its base.
