Was hoping this would fall under an engineering issue, so I posted it here. Have a project coming up where there will be quite a bit of track lighting suspended from an open ceiling. I've only supported track with all-thread, but GC was hoping we could use a type of aircraft cable for a cleaner look. Someone suggested that when you install several heads on a straight piece of track supported from a cable, the weight of the heads would make the track "tilt". Does anyone have any experience hanging track from a cable or some other means other than all-thread? Any input would be appreciated.
i had to hang "floating" track lights in a data center they wanted to
make a showpiece out of, for ATT.
laid all tracklight out on floor, spotted 1/4" holes on back of track.
used a laser to transfer to ceiling... set 1/4" anchors, coupled 1/4"
running thread to them.
set the laser up to throw a level line, cut 1/2" emt the right length
to completely sleeve the running thread, and end up level, correcting
slight differences in deck height above. cut running thread 1/2" short of
sleeve, used rod coupling with jam nut to make almost flush with end
of emt... painted emt flat black.
used allen head button machine screws to suck track up tight to emt.
turned out pretty nice. took a long time to do it right, but it didn't twist,
and if you cut the emt with a tubing cutter, it looks good.
cable will, imho, suck trying to make it work. this was hard enough.
