the central plinth, consisting of the wider
angled sections underneath and a hexagonal core which came up to the level of
the collar around the time rotor. This provided a foot-wide ledge on which to
sit the control panels.
The control panels form a hexagonal ring that sits
on the ledge. Itís built in two halves that are bolted together.
The pieces of the inner core (the hexagon containing
the actual time rotor) are a tall plywood hexagonal tube. I used a table saw to
cut the plywood with 30-degree angles along the edges so that it would form a
proper hexagon in cross-section. I then cut a large hexagon from a plywood sheet
and cut a hexagonal hole in that with the outer dimensions of the hexagonal
I also cut a hexagonal base and used 2x2s to anchor
the hexagonal tube to the base. The top of the hexagonal tube is held together
by the hexagon with the hole, which fits over the hexagonal tube. This sits on
top of six pillars cut from 2x8 wood.
This central time rotor core is very sturdy Ė
Iíve stood on it to reach things high up.
whole thing is nearly completely covered with bathroom board, which makes
it smooth and white without painting. The black panels are matt-black
sprayed bathroom panel. I cut square holes behind every other black panel
for access - I didn't cut every one because I thought this would weaken
the structure too much. Three of the panels are thus removable. All the
edges are clad in aluminium sheet which is folded in a workbench against
wooden formers. This doesn't produce perfectly sharp edges, but is good
enough. I cut the aluminium with heavy duty tin snips.
I was doing this project again, I'd split the plinth in two halves vertically as
it currently won't go through most doorways.
