The
photo above shows the template used to make the Pan-Head for the VSC
“North Star” Field Tripod. The template is made from a sheet of
smooth manila cardstock, typically used for making business cards. Since
each sheet of cardstock was 17” x 8.5”, it was not wide enough to
make a full size template. To makeup for this shortfall, I overlapped
two sheets of the cardstock by about five inches and carefully taped
them together to form a larger single sheet. I was now able to create
the template.
To
formulate the dimensions of the Pan-Head onto the cardstock, I used a
compass with a sharp pencil, a 180° half circle protractor, and a rule.
First, I made a dot with a pencil in the center of the sheet of
cardstock. Using a compass set to a radius to 3” inches from the
pencil mark I made, I drew a circle 6” inches in diameter. Next, I
drew the first of three lines radiating from the center pencil mark out
to the edge of the sheet. Then, I centered a 180°
half circle protractor over the pencil mark and at the same time
spinning it around until the first line I drew lined up with the 0°
degree indicator along the straight edge. Going forward, a pencil mark
was placed at the 120°
indicator at the outer edge of the protractor onto the cardstock. Next,
a new line was drawn from the center pencil mark outward through the
mark I made at the 120°
indicator to the edge of the sheet. To make the third and final line, (which
is another 120°
from the center), I repeated the process. Basically, all I did was
divided a circle into three equal parts (360°
divided by 3, equals 120°),
which formed the three centerlines for the Pan-Head fingers. Now it is
just a matter of establishing the width of each finger for the Pan-Head
and transferring this measurement to each finger on the template. The
finger width can be found simply by measuring the gap between the
“main leg supports” of one of your tripod legs.
Once
the Pan-Head fingers and outer perimeter curves of the template were
drawn, it was time to draw the center hole on the template to match the
bottom of Gary’s CG-5 Equatorial head’s latitude adjustment base.
After that step, the template was cutout from the cardstock with as much
precision as possible. So use a very sharp pair of scissors, or X-ACTO
Knife to insure a crisp edge.
