BFs:

 * BF No. 1:
  * Fujii-san finished tuning.
  * Enzo wired the LVDT, Picomotor and StepperMotor.
  * We measured the keystone tilt at 4 different points and it was at 65.5, 65.5, 65.5 and 65.5.
    So with the differences of 0.1 mm we think we can tolarate this differences.
  * We added cable clamps to the base.

 * BF No.7:
  * Fujii-san disassemble the blades corresponding to the BS and we assemble the SR type blades.

SFs:

 * 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 200[g].
  * We measured the keystone tilt at x points: 65.5mm, 65.5mm, 65.5mm, and 65.5mm.

 * SF (B2-6):
  * Hirata-san, Fujii-san and Tanioka-san checked the optimal load with and without cap (On going?).
  * We measured the keystone tilt at x points: 65.5mm, 65.5mm, 65.5mm, and 65.5mm.

SR3/SRM:

 * Kozu-kun and Enzo finished the SR3 in-air cabling.

 * Enzo prepared the SR3 and SRM rack in parallel (On going).

BS:

 * Kozu-kun and Enzo helped Enomoto-san troubleshooting the BS Oplev issue (On going).




 * We finished tuning of BF No. 1.
  * We wired the LVDT, Picomotor and StepperMotor of BF No. 1.
  

 * We finished tuning of BF No. 7.
  * We wired the LVDT, Picomotor and StepperMotor of BF No. 7.



 * SF check (Hirata-san++).
  * We checked the load capacity with and without the cap.
  * We checked fit of caps. For the SF No.
  * Add cable clamps to bases.
  * Add cable clamps and Cu segments to caps (only if they fit well).
  * Cable LVDTs and steppers.

 * We finished the SR3 in-air cabling.

==== Plan for week of 4/2 ====
 * Mark at Mitaka Mon, Kamioka from Tue.
 * Shoda-san at Mitaka
 * Others at Kamioka
 * --
 * Glue SR3 (if available)
 * Build 2xIM, 2xIRM (if parts available - due 3/30)

==== Plan for week of 4/9 ====
 * Shoda-san at Mitaka
 * Others at Kamioka
 * --
 * Finish IMs and IRMs
 * Build 1xRM
==== Report for week of 4/9 ====
 * Mark glued prisms and magnet/standoff assemblies on the SR3. The SR3 needed to be raised in the box by 0.7 mm to make the prisms go on at the right height, which was done using M4 washers under the PEEK feet.
 * Mark glued ferromagnetic disks on the last 5 IM flags. This completes 2 sets, for SR3 and SRM.
 * Mark configured two pico motor drivers ordered by Takahashi-san as SR3-IM and SRM-BF.
 * Enzo and Kozu-kun finished preparing and calibrating the SF and BF for SR3 and almost entirely finished with those for SRM.
 * Hirata-san built two IMs for SR3 and SRM, and tested the pitch and roll adjustment by running each mass to both limits of its range with the pico driver.
 * Shoda-san worked on the design of the metal SRM.
