Travis and I spent the morning in BSC10 re-lacing the ETMY PenRe, UIM, and ESD actuator cables through the reaction chain and re-securing them in the usual manner so they float with the masses and don't interfere with anything. 

We also reassembled and reattached the PUM and UIM flags in their nominal configuration.  Since we decided to do this after reinstalling the unit in the chamber, we had to remove the PenRe cans again and insert the flags for that stage through the holes in the PenRe mass.  Usually we attach the flags before installing it, however the unit then knocks around a bit while being maneuvered on the duct jack and the arm and we worried they could come free (although never has happened in the past).  Not sure which assembly order is better since today's activity took a lot longer than installing them outside of the chamber.

In the afternoon, we reattached the UIM-Top Mass wire segments and worked our way through the suspension to suspend all 8 masses.  The new ETM16 monolithic hangs!  With the reaction and main chains fully suspended, we observed a pretty good pitch misalignment of the reaction chain and a bit on the main.  We used the (now) easy PenRe Pitch mass slider bar to correct the gross reaction chain mis-pitch and the UIM coarse pitch adjusters on the main chain to do the correction there.  We dropped the ACB back into place (removed the wedge) and observed that the oplev beam was headed back to the oplev receiver port to within ~a cm or so of the diode.  Will continue from here tomorrow with reseating OSEMs and fine tuning alignment.

*Note to self, there will NOT be an oplev reflection from the reaction chain anymore - someone put a hole in the reaction mass!
