I suppose director elements of hollow tubing could be centered on a boom
with "star washers" just a bit smaller than the OD of the tubes, or glue
or silicon caulk...

This is a quagi design where the driven element and reflector are made of wire
loops, not rod, so that's not a problem. Only the directors are made of the rod.
Most elements are about 33 - 34"; I would have to look up exact length.

I think 3' ends up being an inch or two short for driven and reflector
elements on 2M anyway. I have lots of 3" sections (more than a hundred)
of aluminum tubing (in several small diameters), it is very light and
quite strong but a bit hard to work with (and too short for all of the
elements of a 2M beam). Most is larger than 1/4".
