Weight & space & longevity. Boards are heavy and take up a lot of space.
You can use lightweight boards as long as you have a fairly sturdy frame
to hold them. I'm trying to see if I can produce a frame that has
strength because of its shape and that will take whatever misuse is
directed at it during speedy assembly, disassembly, storage and
transport. Cheap & lightweight boards can be stored in loft or replaced.
Structural boards are a problem.


Have a look at some of the point-of-sale display fittings in shops that are
supplied by manufacturers for short-term use and made out of plastic
"corrugated cardboard" - sold by signmaking places as IIRC 'correx'. The
posher (solid) version is 'foamex'. They're study enough to hold
merchandise but don't usually have any frame at all.


Eight rectangles of that, with webbing/velcro hinges. 4 are assembled as
the base:

and four are assembled as the display board on top, rotaed 45 degrees. The
boards have slots cut in so they interlock.

If you make the hinges loose enough what is the outside in display mode
can be folded round to be the inside in storage mode, so protecting the
display.


On the base unit, have an adjustable length of webbing from one side to
the other inside. Most venues will have a surfeit of polychairs, so put a
few of them stacked inside the base, pass the webbing under them and
tighten. This will prevent the base lifting off the floor and toppling.


Very many thanks. Much thought required! ;-)
