Initial Treadsection Work.
First a brief overview. I plan to build
an animated, non-mobile, version of the Robot similar to my
first attempt but with some new features such as a working soil
sampler. I've already collected most of the parts
I'll need, most are available from current vendors but some,
such as the latex legs, are not currently being produced. Hopefully
that will change as vendors bring new products to market.
Treadsection:
This will include the treadsection, side panels, wheels,
tread belts, soil sampler, power supplies, etc.
I
am using a set of aluminum treadsections that I obtained from
Norman Sockwell.
Prep
work: I choose to raise the upper wheel holes from the studio
blueprints to where the hero's wheels actually where, I believe
newer versions of Norm's treads have already made that change.
I also decided that I like the "machined" look
and will not add the radius found in the wheel openings even
though these features where on the prop. This is
in keeping with my plans to make my Robot more like how I remember
it, not always like the prop actually looked "up close".
I will probably texture only the torso and donut (very
lightly, for that "cast metal" look) and go with little
or no texture on the other parts.
I
did a bit of filing, sanding and bondo work then primed the
bare metal with Duplicolor self etching primer (DAP 1690). The
green color looks kind of "military" to me!
Here's
a shot from the rear showing the cutout for the power connector. Again,
not like the prop, but it's functional.
Here's
a shot of the power connector I will use. It
has a built in switch and fuse.
I
found it at www.DigiKey.com,
( Q300-ND Power Input Panel, $7.85 ).
I also purchased a cord too ( Q116-ND Power Cord, $4.88 )
Finally,
here are the power supplies I've selected.
They are 12vDC at 25 amps and 24vDC at 12.5 amps with built
in short circuit protection.
The 24 volt supply is strictly for the all the animation motors.
The 12 volts will run everything else.
I purchased them at www.AstroDyne.com,
model #'s AS320-12 & AS320-24.
Small and lightweight, but not the price! $125 each.
