Vibration Absorber Viton Shim Swaps
(Corey, Jim, Vincent)
Yesterday (1/24) afternoon, Jim and I went in and swapped Stage1 Viton Shims (these are located under weights) mounted on the Access Walls of Stage1. We removed 1/16" shims & inserted 1/4" shims. Vincent will then make measurements on the system to gauge their performance. (note: before the 1/16" shims, 1/8" shims were looked at).
The work above was for H2's BSC8 ISI System, and obviously the alog above should be marked for H2 (but I can't edit that any more).
