Children's theater volunteer here. I inherited a set of 8' tall by 32" or so wide peri and made a pair 10' tall to match. At that narrow a
base, they tend to be quite tippy. The 10' always have at least 20 pounds of sand in the
base and the 8' get
ballast if the floor is uneven or it may be the littles interacting with them. I dig
@StradivariusBone take on how they are mounted on the
base, ours just screw through the
face and over time, the material breaks down due to the number of holes. The ledger does add to the
thickness during storage but would make assembly so much easier. Without it, it's a gamble whether or not they will stand vertical or tilt off to one side. Our design is basically a
flat with the long
edge cut on whatever angle makes the 3 corners meet at a
point. This does not give a lot of material for screws, I wish they had been designed to use loose pin hinges. Ours are on 3 swivel casters, they get pushed all over the
stage and sometimes off
stage during a show so none swivels would be a nightmare. If you only want clean rotation, the fixed casters would make sense. The original bases were made with 1by. No idea how that made sense, driving a screw through the
face of a
flat and into the
edge of a 1by isn't easy to say the least. I need to remake them with thicker material and maybe figure out hinges.
Here is a gratuitous picture of my truck with a 10' peri in the back.
