ETMY SUS extraction Status

Between yesterday and today, Travis and I finished staging the weld room at EY:

- Finalized "furniture" layout

- Wiped all equipment down

- Worked through some power issues - need something from Richard, working on it

- Discovered the wrong blue duct jack Genie SUS lift was brought down - correct one brought down by Bubba this am


We also got the suspension to the point where we are really ready to put it on the install repair arm tomorrow morning first thing and bring it out for further disassembly:

- Staged in-chamber tools and pans

- Installed temp catch trays, face shields and added fiber guarding parts

- Pulled off all top mass BOSEMS and dropped the top mass down to make slack in wire segment below, used top stage to do this

- Pulled suspended lower cables up the reaction chain

- Removed a few large panels of flooring in the chamber in order to remove the sus structure sleeve, replaced the floor panels (note, found a bolt and nut under the flooring - also wiped the chamber bowl flooring many times to remove lots of particulate that looked mostly shiny, or PEEK, or viton)

- Adjusted all masses so that there was slack and removed the wire segment joint to the top of the UIMs

- Locked down all masses

- Laced up cables to arm elevator and tested functionality

 

We should be ready to start the extraction tomorrow morning, barring telecons, etc.
