Last week’s brilliant solution to modify the Fries 3×65 15-perf pull-across camera was partially unsuccessful when the camera was run at speed. Join me as I rethink the problem with the pull-down assembly on this Fries 3×65 camera movement.

You might remember this Fries 3×65 IMAX format camera from the repairs I did on the movement last spring. The owner brought to my attention that people who have shot with this camera in the past were concerned with the way the pull-down claw and registration pin assemblies were held in place. Their feeling was

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

And so we come to the end of my project repairing the Fries Engineering Ultra 70 3×65 IMAX-format camera. This project was quite challenging. 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

An interesting camera came through my shop for evaluation this week. This is a Fries Engineering Ultra 70 (3 X 65) camera that shoots IMAX 15-perf pull-across 65mm film. I am evaluating what work needs to be done to get it up and running again, but currently it isn’t pulling film. Fascinatingly large and heavy,
