Subject: MC2 chamber anchoring tightened 

Quote:

 Thinks to do before the NEXT realignment:

B,  tie 4 ancher bolts on table legs to the floor

C,  tie 4 dog clamps between table and chamber

D,  check the locked position of the 4 x 4 positioning screws

E,  check bellow protecting 4 tubes are not shorting

A,  here is the concrete  slab cut

 

It reminds me to check the  IFO vacuum envelope dog clamps on the chambers to floor  with torque wrench.

 

 

 I locked the PMC and MC resonated in TM00 right on. Than I started checking anchoring screws with the torque wrench.

B,  3/8 foor bolts were tight, They were set  to 50 ft/lbs

C,  dog clamp bolts were tight at 80 ft/lbs

D,  horizontal position locks were lose. They were locked by finger.

E,  below covers were reset not to short

The MC is locking in TM01 mode now
