Projects Arri BL Rig
Intro
This is my first attempt at building a jib. It was actually constructed mostly from scrap material without having a previously thought-out design.
Details
The head is a gravity-actuated, self-leveling type, and it also provides a degree of freedom allowing the camera to pan. The camera can tilt up and down if its direction is parallel to the boom. The axle of the boom is a 1" diameter wood peg or dowel. The base is only 5/8" thick MDF with no stabilizing beams, so it's not as sturdy as it could be. It has two fixed casters and two swiveling casters for mobility. The counter-balance end of the boom can be weighted with sandbags to make it easy to raise, lower and steady the camera without an assistant.
Photo
More pictures will follow. I have to scan several production photos from the shoot for "The Snack." This image is obviously a screen capture from when I ran out the last few feet of film in the other camera I was using.
