HAM5 Components B&K Hammered
J. Kissel, H. Radkins

Hugh and I hammered essentially everything big bolted to the HAM5 table this afternoon, including: 
    OFI Cage (with new baffling?)
    OFI Side Baffle (drawing??)
    SRM Cage (with new Venetian Baffles D1700257)
    SRM Table Baffle (D1700270)
    All 3 HAM ISI Front Guard "Beard Cover" Baffles (D1700265)
    SR3 Table Baffle (D1700270)
    SR3 Cage (with new Venetian Baffles D1700239)
    SR3 TCS ROC Heater (D1500258)
    ZM2 Cage + Spacer (D1600094)
    ZM2 Septum Window REFL Dump + Spacer (Standard ISC V-Dump & Post + D1700041)

Attached are all the pictures. 

Analysis will come, but my first impression from the raw data (without comparing to any previous data):
- The SR3 Cage has several High-Q features at ~300-400 Hz
- The ZM2 Cage and ZM2 REFL Dump structures have High-Q features at ~120 Hz.
- All other stuff is well-damped.

Notes: 
- When hammering the OFI Side Baffle, we left the accelerometer in the same location as when hammering the cage itself.
- When hammering the SRM Table Baffles and the Plus X and Middle Beard Baffles, we left the accelerometer in the same location.
- When hammering the SR3 Table Baffles and the Minus X Beard Baffle, we left the accelerometer in the same location.
