Homemade Practice Gear Head
I feel that a gear head responds to camera framing like a steering wheel does
to driving a car. It happens without even thinking once we learn the right reflexes.
To learn a gear head an aspiring operator needs one available for practice.
When I started shooting sound the cameras were so big they demanded gear heads.
I bought a used Worrall to learn. Today gear heads are much more expensive.
Here is one design that a mechanic can build for less than a $100 in parts.
Ones can be also built with belts and pulleys and also with small high ratio
gearboxes. I felt the one below was easier, but look into your resources before
trying it. A camcorder makes a convenient viewfinder.
These milling head attachments are cheap from the third world. Look carefully
at my design, as you might not find a head the same with the rotating top (which
became my bottom.). This design turns the head up-side-down and uses the rotating
top feature as the pan bearing. I replaced the original rotating top, as it
was almost as heavy as the rest of the head.
Make sure the 4 tilt arms are the exact same lengths and holes in the brackets
on the head and camera plate are symmetrical. I made these out of clear plastic
to make it easier to see. I would suggest metal or stronger plastic.
This head is only for practice and would elicit howls of laughter on the set.
Remember that line, "They all laughed when I sat down to play the piano". You
can learn in the privacy of your home or yard. This rig has only one speed and
a limited range, but you can effectively change the ratio by changing the zoom
size and distance to the objects that you are framing. You can also follow subjects
on your TV. You can trace circles, squares and figure 8's. The hardest move
is people getting out of a chair. Once you feel you have the right reflexes
you might ask someone to walk around and get up and sit down for you. Also practice
with both eyes open.
If you have other designs I would be happy to include them here and credit you.
