TMSX was balanced on the spot without using the balance bridge, and it was just fine.

First the top mass was fixed level using EQ stops, then table/tele was hung, balanced while half-supported by Genie lift using the movable masses, and I have to say that these are much smoother than the first article. Since the table/tele was measured 79.5kg, we added 2.5kg masses (3x500g, 5x200g).

Next the top mass EQ stops were all backed off, the table cloth was moved around a bit to allow the top mass to float freely, and of course we had to use the top slide masses to balance it.

As was observed at LLO, there were two spots where the clearance between the mass and the table cloth is uncomfortably small (less than a millimeter): One is the back right corner and the other is the front right EQ stop. Table cloth was moved to provide maximum clearance (but it is surrounding the mass so it's a zero sum thing).

Anyway, the suspension is hanging freely, the only thing is that the side BOSEM is almost touching, and that's why Caltech people sent us a modified BOSEM mounting plate, which I gave to LHO C/B today.

We haven't measured the height of the TMS, and we need a help from either AOS or SUS to measure this using optical level.
