With my work on the Dykstraflex camera complete, I have returned my attention to Mitchell 46. I dusted off the setup on the mill, re-indicated all the surfaces that needed to be true, and began to make a tool path map. I had transferred the actual position of the camera movement to the aluminum plate […]

This past week I had the privilege of doing preventative maintenance on the Dykstraflex camera for the Academy of Motion Picture Arts and Sciences. I serve on the Academy’s Technology and History Subcommittee, and following the restoration of the Dykstraflex camera crane, subcommittee members were concerned that the camera may have developed problems after having

It’s a little late for Star Wars Day, but we wanted to share this latest project in anticipation of the premiere of “Obi-Wan Kenobi” tomorrow. Previously, in 2019, I completed a major restoration of the Dykstraflex camera crane for the Academy of Motion Picture Arts and Sciences. The restored Dykstraflex was prominently displayed at the

Despite my good intentions, replacing the roof on our building interfered tremendously with progress on Mitchell 46 this week. My next step in restoring this camera was to prepare the casting so it can be accurately mounted on the milling machine. There are very few things on the casting that remain true, so the only

In order to move forward with the machine work on the replacement bottom plate for Mitchell 46, the front plate had to be installed so that three important things could be established: First, the proper thickness of the front plate so that the camera will slide freely on the rackover L-base and still light trap.

After the puzzling and disappointing failure of the Loctite adhesive last week (Loctite has never failed me before!) I went through a process of cleaning and degreasing the camera casting and the replacement bottom plate. I spoke to an adhesive expert, and he recommended 3M’s Scotch Weld 2216 2-part epoxy. The process required 4 arms

The task at hand with Mitchell Standard #46 is now to put metal back where it was unceremoniously removed. This problem is compounded by the fact that so much material was removed from the bottom of the camera casting, that some areas are perilously thin. After three days of contemplating the next steps, and a

Progress at last! Sadly Mitchell 46 has been far more butchered than I had anticipated. Still, we shall persevere. I managed to get about 90% of the working pieces out of the camera casting, though the shutter shaft stubbornly remains in place due to corrosion. The screw that holds the focal plane shutter to the

I have been working minus one thumb this week after having some minor surgery last week, and am unable to lift anything over 5lbs. for a few more days, so a brief update this week. I was able to calculate how much material needs to be added back to Mitchell Standard no. 46, as well

The starting point to restore Mitchell Standard #46 is to determine exactly what and how much material was removed from the original casting. The problem with this particular camera is that the previous owner machined away all of the material that registered the dovetails, the rackover registration plate, and the rack gears that slid the
