Jim, Jennie, and I started working on converting the HAM3 D5 feedthru from D1002874-v9 to D1002874-v10. This feedthru (in -v9) serves "corner 2" of the HAM2 ISI. 

We didn't finish, but here's how far we got (all in the -X / -Y / -Z corner of the chamber where the D5 flange is):
    - Powered OFF all HAM3 ISI sensor (via ISI interface) and actuators (via coil drive) in the SEI-C2 rack.
    - Disconnected the in-air connections (2x 3W3 actuator cables, 2x BNC CPS cables, 1x GS13 D25 cable) to the feedthru. (easy, by hand / thumbscrew)
    - Removed all strain-relief cylinders (easy, simply hose clamped)
    - Disconnected as many in-vac connections as was easy (Horz CPS BNC, Both 3W3 actuator cables)
    - Removed the dual D4-2B 4.5" flange, wrapped and tagged it with the copper gasket on to protect the knife edge
    - Covered the exterior / air-side in foil, mindful of the knife edge.
    - Restored C3 parachute 

I could not easily thumb-and-finger off the Vert CPS BNC (Jim says they're notoriously difficult on the clean side).
I could not find the right allen key size to unscrew the GS13 D25 connector.

We'll pick it up on Monday next week (2026-06-08).
