HDWTD MAKE STATIC SCALE PROPS<br />
This is a close-up of the<br />
molding halves with the<br />
slightly thickened resin brushed in.<br />
This layer is necessary to prevent<br />
the cloth from showing through the<br />
blade and is best left to harden for<br />
about 30 minutes to an hour before<br />
you apply the first layer of cloth.<br />
This photo was taken<br />
immediately before I joined<br />
the halves. In this stage,<br />
all of the material is wet.<br />
On one half, I filled the<br />
perimeter with a mixture of<br />
resin and fibers and strands,<br />
and I placed wet carbon<br />
roving on the other half. After<br />
joining the halves, I inserted a small brush through the root hole to<br />
press the roving to the inside of the leading edge and the root.<br />
The P r0 P came out of the mold<br />
shiny and glossy. After trimming<br />
off the excess resin, I had a perfect,<br />
strong and lightweight static prop blade.<br />
Production of subsequent blades is<br />
very straightforward and requires<br />
only a fraction of the time that's needed<br />
to make the first blade.<br />

Of course, three blades<br />
alone do not form an<br />
air screw. This photo shows all<br />
of the parts required to form<br />
the completed item. I made<br />
the static spinner from carbon<br />
in the same mold that I used to<br />
make the flying spinner. I used<br />
some hard foam to make the<br />
backplate and the purple<br />
blocks that serve as blade<br />
retainers. I used a graphics computer program and printed my<br />
own decals using Super-Cal decal paper.<br />
This is the completed<br />
static prop ready to<br />
go—my latest pride<br />
and joy. In VA scale,<br />
the prop's diameter<br />
came out to be 20<br />
inches.<br />
