TMS work today (Cheryl, Keita)

TMS ISC cables were attached to the mass using metal clamp with kapton tubing.

Took longer than we first thought because we had an interference with the screw tip of the clamp and the side of the blade, and had to experiment with shimming. Too thin a shim and your screw protrude more from the back and interfere with the blade. Too thick and your screw doesn't go all the way through the threaded hole of the bracket, and the thickness of the bracket seems to be smaller than 1/8, much thinner than you would  expect from 1/4-20 thread.

Then the cables were attached to the cube rather than the ceiling using peek clamps. This is because we don't have a good tapped hole to mount cable clamps under Bosch frame. Once it is moved to the test end we'd have more options, but in the mean time this should be good.

The top mass was rebalanced, table cloth was readjusted to maximize the clearance (the tolerance is extremely tight), BOSEMs were repositioned but we couldn't proceed as there was a trouble attaching the side BOSEM to the new mounting plate (see another alog).

In parallel with side BOSEM effort, we still need to mount the dummy feed through to the Bosch frame, put the BOSEM cables on, and set the height of the BOSEMs correctly, which looks like half day's work, before we can test the SUS.
