| * Craned in the PI. * Assembled the thrust bearing holder that receives the PI-SF rod. (It originally had a burr that prevented the bearing from seating properly, and so required filing and re-cleaning.) * Hooked the SF and lowered the jacks under the SF to suspend the SF/... section. * The top filter rose when unlocked, and required about 1.8 kg to send it back down. Therefore we may be OK - the top filter seems to have about 8 kg more capacity than as measured by G&M. The hex cable clamp (≈0.25 kg) and the cables between the PI and SF still have to be added, but we can get an extra 3 kg by removing one of the three Cu damper segments (and rearranging the other two). * Built and installed three LBB blade units. * Kept debugging the SF LVDT. We repaired several broken wires, but it's still not behaving correctly. |
