==== Report for week of 2/26 ====
 * We routed all the cables from the BF level up via the flying saucer to the SF.
 * Hirata-san tried filing the SF cap to improve the fit, but without much success.
 * Hirata-san installed the Cu segments and cable clamps on the SF cap and the SF LVDT and FR cables.
 * We cabled and tested the BF cap picos and the SF LVDT and FR. (The LVDT still needs a full calibration.)
 * We worked on recovering the IM OSEM alignment.

 * Calibrate SF LVDT.
 * Weigh SF/... section.
 * Get SRM tank mushroom section installed (Hirata-san, Kimura-san)
 * Set up for rebuilding of two BFs.
 * BF No. 1:
  * Fujii-san finished tuning. Optimal load: 52.15[kg]. Resonance frequency: 0.37[Hz]. Optimal height: 64.7[mm].
  * We wired the LVDT, Picomotor and Steppermotor.
  * We measured the keystone tilt at different points and the diferences are within 0.1[mm]
  * We added cable clamps to the base.

 * Hirata-san and Tanioka-san set up the frame to check the SFs.

 * SF (B2-5):
  * Hirata-san, Fujii-san and Tanioka-san checked the optimal load with and without cap. The optimal load changes about 250[g]. The cap didn't came out smoothly.
  * We measured the keystone tilt at different points, and the diferences are within 0.1[mm] (65.5, 65.5, 65.5, 65.4)

 * SF (B2-6):
  * Hirata-san, Fujii-san and Tanioka-san checked the optimal load with and without cap (On going?).
