| ==== Report for week of 12/25 ==== * Hirata-san got the L-brackets machined and washed, and installed them on the IM ring bars. * Shoda-san recovered the BS from the power outage on 12/25. * Miyakawa-san fixed an issue with the SR2 RTM which had prevented it from running. * Shoda-san, Hirata-san and Kozu-kun weighed the IM without ballast masses, and then added the lower masses and installed the IM on the assembly frame. * They cleaned the assembly frame and installed new jack receptacles on the load gauge adapter. * They installed the winch system on the IM, and inspected the clamp pieces for possible scratches. * They ran cables for the SR2 steppers and OSEMs. * They calibrated the BF LVDT. |
==== Report for week of 1/29 ==== * Mark made two sets of in-air pico splitter cables (each with a triple for IM and a double for BF) for SR2 and SR3. * Fabian, Hirata-san and Kozu-kun worked on cabling and testing the IM pitch/roll/yaw picos, the BF FR and the BF LVDT. The LVDT connections were initially unreliable and Hirata-san had to redo the pins on the coil wires. * Fabian installed ballast masses in the BF. * Mark worked on schedule. * Mark did inventory of the stepper motor drivers (many were not accounted for on the wiki and/or JGWDoc and one is missing) and reserved two for SR3. |

| ==== Report for week of 1/9 ==== * We weighed the mirror in its box (and later the empty box), and the RM. * Fabian worked on the SR2/SR3/SRM mass budget and did an inventory of spare ballast masses. * We hung the SR2 and RM. * We assembled the bottom section of the security structure below the RM. * Hirata-san gave up on waiting for a third quote for the blades and blade parts and started the ordering process. * Hirata-san got rod cable clamp parts from Takahashi-san and worked on drawings for the improved BS vertical and yaw adjusters. |
==== Plan for week of 2/19 ==== * Enzo back from Tuesday. * Shoda-san at Mitaka * All others at Kamioka. * - * Lift BF/... section and check total mass and balance. * Cable and test BF picos. * Add section of SS up to SF ring. * Bring in SF. * Hook BF/... section. * Route cables up to under SF. * Check/adjust total mass of BF/... section. |
