Last week’s experiments with Showscan lenses got me thinking about the Showscan equipment I have left around the shop. Among these leftover pieces is this CP 65 camera body that lacks most of its electronics and its movement. The camera casting is serial no. 101, and as I looked it over, I thought it would […]

I have shown you my recent work repairing the Fries Ultra 70 3×65 IMAX format camera. The owner of this camera doesn’t have lenses that were made specifically for it, but it occurred to me that the lenses that were built for the CP65 Showscan cameras “might” work in this situation. This week I experimented

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

Coming up with retrofit parts that would preserve the function and integrity of the movement, but still be serviceable in the future, required a lot of careful thought and planning. Because

Last week’s adventures ended in the machining of a successful replacement hub blank for the Fries Ultra 70 IMAX format camera. This week, I machined the required features onto the hub blank so the flywheel could be permanently mounted to the movement and timed correctly to the shutter drive. The process was straightforward, if a

This week I continued work on the Fries Ultra 70 IMAX format camera. It was mainly a week of head scratching, doodles, starting over, and eventually creating successful parts. As I mentioned last week, my plan is to machine a new flywheel hub that will attach to the movement using the remaining threads on the

Back in March 2021, I had a chance to evaluate the Fries Engineering version of the IMAX camera to diagnose why it had stopped working. 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

While I love all of the new stuff that has come in recently, I am quickly being overrun by boxes and loose equipment. It became necessary to re-do the showroom and make more shelf space. A good friend of mine built me this wonderful display rack, and I have spent the week mounting the shelving
