I put another roll of film through my No. 1-A Folding Pocket Kodak Special after making some modifications to make it easier to use 120 rollfilm.

My inspiration came from a fine series of articles by Greyhoundman, who converted his Kodak box camera.

The easiest part of the conversion is the modification of the 116 take-up spool. I made a couple washers from the rubber backing material off a mouse pad, cut them in half and glued them to the inside faces of the spool end disks. The 1/8-inch thickness is just right to shield the edges of the 120 film against the light.

For the supply-side, I made a film holder from a plastic Adox film can. A hole in the bottom and another in the rubber disk holds everything in place securely, and the film comes out through the slit down the side. Besides being simple to implement, this solution didn't require any irreversible modification to the camera.

The film rails need to be just an eighth-inch wider on each side to properly mask and support the 120 width film. I used some black mounting board. The first strip was made a bit wider so it would slide under the existing frame rails and help support the new ones. On top of that, I glued two more 1/8-inch-wide strips, and these were also glued on the outer sides to the metal frame using hide glue. The mounting board is tough stuff to cut, but using my mat cutter enabled me to make the strips thin and straight.

Greyhoundman hit on a nice solution to frame spacing with the discovery that relocating the red window to the center of the camera back enabled him to use the center row of numbers on the 120 backing paper; using every other number yields six non-overlapping frames per roll.

I was reluctant to drill a hole in my nice old Kodak folder to get the proper frame spacing. However, I found that the existing red window in the lower right corner of the back let me make use of the 6x4.5 framing numerals to get five evenly spaced frames using every third number, starting with number 3.

I'm not sure that I made any real improvement in image quality through the conversion, but the camera is quite a bit easier to use. One problem that cropped up was that the film edge is closer to the red window, and I am presently getting quite a bit of light leakage onto that side. I'll try painting out half of the window, and I'll also see if some well-placed foam light seal helps.

So, still a bit of work to be done, but I only have an hour or two into the project, and it turned out to be quite a bit easier than I had anticipated.

The information presented here originally appeared in a posting at the nelsonfoto forum. Several other people with experience in using 116-format cameras contributed additional ideas in that discussion for adaptations and frame spacing.

Take a look at my web page on the No.1A Pocket Kodak for an even easier way to use 120 in a 116 camera. The design of that slightly newer Kodak makes it possible to use standard 120 roll film with no changes to the camera or any need for re-rolling film.
