Like
many ideas, mine was brought to the
light of day glowing with pomp and
pageantry on a restaurant napkin.
Well, to be more accurate, on the
back of a paper restaurant place
setting that had grease smudges on
it and looked a lot like the picture on
the left only the lines weren't
nearly as straight.
In it's initial design, the chair
itself was going to incorporate two
8" diameter Tesla Coils (sisters)
at the top of each rear seat post
that would send a blazing blue bolt
of electricity to each of the two
orbs while the unfortunate guy
taking the brunt of this torturous
death was leaning forward and
shaking violently. Then when he sat
back upright for a moment between
full body spasms, the bolt of
electricity from both coils would
zap to a metal head cage he was
wearing, really giving him
something to whine about.
-Tragically-
 
That couldn't happen. The chair was
going to be literally filled with
on board electrical gadgets to make
all elements of this scene come to
life and I learned there was really
no practical way to fully isolate
those onboard delicate circuit boards from being fried into
puddles of carbon each time the
coils were triggered. So this
element had to be scrapped.
However, among the other animations
our prop will have in common with
the Shake and Bake, we would be
able to create smoking skin at the
feet and wrists, and, going a bit
further I replaced the Tesla coils
in the imagineering stage with a
chaotic fiasco of electrical
insulators and heat sinks that
would also emit excess smoke
created
by the dead
ground
created when shocking a person to
death. The re-draw of the new chair
would then look similar to the
drawing just above on the left
here. Not as dramatic as the blue
lightening bolt-like spark from the
coils, but it would have some
redeeming value in our finished
product.
Take
a look at the prelim drawings

thumbnail for a larger image.
Since
this project has been engineered on
computer, I
was
cautiously
optimistic that I could build the
chair and pedestal to the
dimensions shown here before
prototyping the dummy's movements
and dimensions with a real life
mockup and it did work out very
well. To the left and right you
will see draftings of the
chair including its dimensions. The
construction is made up of 3/4"
plywood and is entirely hollow.
This gives us channels throughout
the legs and arms and even under
the seat to run our wires and fog
piping.
In
this photo on the left you will get
a clear look at the seat, which is
a separately constructed box. Since
this chair is all wood construction
and will be subject to rather
demanding vibration and concussion
from the animations of our dummy,
we need to use this as our anchor
of rigidity for the entire build. It is
important to note that the box is
built with a face frame on each
side for just this reason. You can
either make a face frame using
solid wood, glue and dowels or face
frame screws, or using the simpler
method of cutting out your opening
in a single piece of plywood such
as I will be doing here. Any of
these three will produce the same
desired result, a laterally stable
box to base the rest of the chair's
features on. This is where our
pneumatics will be to animate our
thrashing guy as well as an
isolated area to mount the speaker.
We will be employing two air rams
inside, one for the chest and
arms and one for the legs. Our
hopes are to completely eliminate
any noise the air rams and exhaust
might have, so this box will need
to be sealed off for operation.
This is why the need for a floor as
well as the separated area for the
speaker. More on that later. Once
the prop has been completed, the
side openings will be covered
up with 1/16" polished diamondplate
aluminum that will kill 95% of the
sound from inside.
The
pedestal shown on the right is
where the fog machine, the
expansion chamber (based on the
system that makes the Fog, On The
Rocks work so much differently than
other coolers) and electronics
will be stored. Not only will this
space be handy for our purposes of
keeping this prop entirely self
contained but it gets the view of
the scene up higher to pronounce
the animation to the viewer's eye.
You will notice here that the back
of the pedestal is hinged, allowing
access to the electrical and other
items it will store inside.
I have decided to offer
the actual cut out list I used for
mine for
your benefit. I've tried to get
each piece that was actually used
but there will be a couple of minor
pieces you will have to add to it
such as the braces used inside the
pedestal that the door closes
against and the ones just under the
front legs of the chair that will
allow you to take either side off
without the pedestal's top sagging
under the weight above. If you find
any sizes here to be off by even
1/4" please email me so I can make
the corrections here.
