   Yeah I was thinking piano hinge or whatever equivalent I have laying   
   around left over from repairing boat compartment doors for the roof/lid   
   hinges.  What I was more thinking about was the pivot points for the   
   connecting links between the trays.

   The hardest part of my suggestion may be finding short enough screws. The   
   brass tubing "shoulders" could be parted off quickly with a rod or drill bit   
   inside to retain them and quick length setting with a ruler, as they can be   
   a bit too long. Another possibility is undercutting the head, there's more   
   than enough metal on a Phillips pan head to turn a step for sheetmetal. All   
   the common number-size machine screws except #8 can be chucked in a   
   fractional 5C collet. Even on my old leather-belt lathe with a handwheel   
   collet closer, making one cut apiece in a dozen screws goes pretty quickly.   
   Usually they are clearance cuts to eyeball accuracy.   
      
   I modify small screws in batches so I made cup shaped screw holders tapped   
   for the sizes I use, up to 1/2" which was for battery mounting posts for a   
   Segway project. The walls of the cup are about the length of a 5C gripping   
   surface and the back is bored out to cut off protruding threads short. I cut   
   a shallow groove near each end to make removing them from the collet easier.   
      
   The best one, which I've made only for 3/8-16 so far, was tapped full   
   length, grooved on both ends for the O rings that keep it together, then   
   sawed lengthwise in thirds to align with 5C slots or pairs of jaws on the   
   6-jaw. It grabs the whole thread, not just the crest like a collet which is   
   less secure.
