HAM2 Beard Baffle for SPI Placed and B&K'd on Friday

Mitchell and I placed the new central beard baffle with a cutout for SPI on HAM2. It went on without issue after Mitch reminded me how to adjust the panels.

I then attached the accelerometer to the L bracket and tried hammering in various places. There wasn't much real estate, so I'm not sure how this will turn out. Data still needs to be analyzed, and I'll post pictures of hit locations then as well.

For clarity, this is a D1700265-V4 Ham ISI Table Baffle "Below Table"

No SN's for each of the 3 asseblies were tracked during initial install. Comments and the new SPI type 3 baffle panel as well as the type 2 that was removed will be added to D0901083 WHAM2 top level. Originally, pre SPI, the configuration would have been 2x type 01 and 1x type 02. The type 02 changes to a type 03 for the SPI configuration.

Work Permit 13238:

Change out +X-side, center, HAM2 ISI table baffle from D1700265-v4 Type 2 to D1700265-v4 Type 3 in support of SPI HAM2 ISIJ assembly install (WP:13237) per DCN E2600005 that converts HAM2-H1, XYZ Local for HAM ISI BAFFLE ASSY D1700335-v1 to -v2.
