Continuing on from my work last week replacing the belts in the ARRI 35 BL 4S, this week I set out to repair the broken video tap. The damage was likely caused by someone mistakenly picking up the ARRI camera by the video tap. I have seen this on a number of other cameras from […]

A few weeks ago, a dear friend of mine called with a slight amount of panic in his voice to tell me his venerable Arri 35 BL 4S had stopped working. After a little detective work over the phone, we concluded that the problem was likely with the drive belts, an unfortunately common problem with

The immediate problem was pretty straight forward: There is a flywheel that is part of the movement, but that also acts as a coupler between the movement and the shutter

A few weeks ago, an up-and-coming cinematographer wrote to me and asked if I had any 16mm animation cameras. He was planning to shoot a table top animation short subject. As I don’t currently have any 16mm Acme or Oxberry cameras, the next camera that came to mind was this lovely 16mm Mitchell Pro. The

A friend and fellow collector called me and asked about the Mitchell BNC rackover camera that I just acquired (serial #357). So this is the first of the collection I decided to take a look at. Surprisingly, this camera is in remarkably good condition. The camera turns over smoothly, there is little or no rust

An interesting question was posed recently to the committee I serve on at the Academy of Motion Picture Art and Sciences asking about the history of geared pan/tilt heads. The questioner was only aware of the Worrall geared head, so many of us contributed our experiences with other styles and manufacturers of geared heads that
