• With growing concerns about the state of the hinges on the acoustic door to the Laser Room, RobertS and I first tried (lightly) greasing the hinge pins with some of the Bralco or Castrol low-vapor-pressure grease used for the vane-axial fans.  Then, with the loud stick-slipping and flexing of the upper hinge still occurring, we removed the jamb-side hinge half (see photos below) after supporting the outboard end of the door leaf.  We found what appears to be excessive wear on the contact portion of the hinge pin (these hinges lift the door off of the threshold as the door is opened by rotating up an inclined plane).  We wiped the old grease off as best we could both on the male hinge pin and the female receptacle of the door-side hinge half.  We then greased the pin and re-installed the jamb-side hinge half.  The door operates much more easily and smoothly now without any obvious indication of the stick-slipping that was occurring earlier.  We should probably service the other two hinges in a similar manner.
   
• Using a nice, ~ 4 ft. long section of cable tray that PeterK got from RichardM, we started the process of organizing the cables around and under the PSL table in hopes of being able to work there without standing on cables (see photos).  We moved the ten spare Lemo cables into the tray, then improvised a method of holding them, ordered from numbers 1-10 on the side of the table (see photos).  This seems to be a big improvement for convenience and particulate control.  Lots more to be done in this regard.
   
• We had to move the dust monitor slightly in order to install the cable tray under the table.  The kapton tape holding the dust monitor intake nozzle came loose so we mounted the intake a bit more permanently.  We'll likely want to find a better location for the monitor and intake nozzle, maybe just down a foot or few toward HAM1 and mounted higher such that the input nozzle is closer to the center of the table and not so susceptible to spikes from people brushing against it as they work along the side of hte table.
