of us, one could consider the ball bearing approach, where the top of the 
boom has a "T" section, and two ball bearings are affixed underneath and on 

I have often wondered if a graphite bearing surface
might work since graphite is a lubricant.
Just have to be careful about loading because
graphite is relatively weak I should imagine.
