[Build] Lighting

[jim]

   we currently have five panels in the place and we're 
pretty much out of money: we still have to buy pipe and 
boxes and receptacles and breakers and such. 
   there's no money left for another panel. 

   some lights are powered by the rear panel, other 
lights are powered by the front panel. installing a new, 
sixth panel requires re-routing pipes as well as wires 
to the new panel as well as a new pipe from the currently 
over-loaded panels to the new panel. 

   yesterday i got shocks from white wires that come out 
of the front (unenergized) panel. this means the previous 
work indiscriminantly tied any return to any neutral wire 
rather than the proper neutral wire. today i'm pulling 
all the wires from some of the pipes and redoing them. 
   for the place to be usable for the move-in, there has 
to be essential electricity working. 

   zedd claims it's possible to start painting thursday. 
when the spray gun is at work, no one else can be in the 
place, so there'll be a hiatus on anything but painting 
starting thursday or friday. 
   it'll be all i can do to get essential electricity 
working by then. 
   it makes sense to group the lights per my previous 
email to this list. pipes and wire runs will be so 
re-routed. 

   those who have ideas for lighting, please present your 
ideas with respect to grouping and power needs. you'll 
get your ideas implemented sooner if you help with the 
basic infrastructure work (pipes, boxes, wires, lots of 
screwing screws...).
