BSCISI#2
It has been decided that we will live with the 0.030" counterclockwise twist in the system. So the next step is to balance the Stages and then adjust the Lockers accordingly (the desire is for the system to move minimally [0.000-0.003"] when locked and unlocked). What we will lose here is that we will not be able to use the Alignment Pins when transporting the system (they won't work because the 0.030" is enough to not align the Pins in their holes.
Since we are hoping to receive GS13's (and other seismometers) soon, we have decided to wait on positioning Lockers until we can install these Sensors (so that we don't end up re-doing balancing).
BSCISI#3
Have been at a standstill for the overall assembly because we have been waiting on large plates; however yesterday, we received the balance of our plates (8 in total), and half of these will be loaded in an oven today.
Stage0 has been assembled and is on the Test Stand. Unfortunately, we only had two Blade Posts, so only two have been installed on Stage0.
For background work, have focused subassemblies. As of last night, we are roughly about ~90% done with all the assemblies (i.e. Small/Large Actuators, Lockers, Flexures, Sensor Assemblies). We are missing a few parts and won't be able to finish them until we get the parts (i.e. 1-3/8" bolts for the Lockers and the Small Actuators for example).
Holes Not Tapped Correctly On Batch Of Small Actuator Magnet-to-Stage2 Interposer Plates (D0902134)
While helicoiling parts yesterday, it was noticed that one part had issues with a hole. For D0902134, the 1/4-20 holes for it weren't tapped correctly. They were too small for the helicoils and a bolt wouldn't fit in. Found this issue with the (3) we pulled out for BSCISI#3. So, ran a 1/4-20 Helicoil tap in all of these holes. We should check to see if we have this issue with other plates and how many others.
Believe there was some operator error on some of the holes I helicoiled because when a bolt was run through some holes the bolt was noticeably "loose". I believe this is due to me not tapping very straight and taking several attempts to tap the hole--just need to make sure to start straight and not make several attempts!
