Developing 116 Film in a Paterson Tank

I recently found an exposed roll of 116 film in an Ansco Buster Brown 2A camera. 116 film has been out of production for quite a while, and resources for developing this size of film is very limited these days. I'm showing here how I was successfully able to develop a roll of 116 film at home with modern Paterson film developing equipment.

Here is a picture of all the materials I used to set up the reel. The important pieces are a single complete Paterson reel (pictured on the right) and a small half from another Paterson reel (the half that fits snugly onto the center tube):

The key to the function of this setup is the half  reel nestled into the top half of the main reel. This keeps things concentric, and without it, the larger diameter half of the reel would be loose and wouldn't hold film.


The extra half reel is placed backwards onto the larger half of the full reel, such that everything sits well-aligned on the center tube. Here's the final arrangement assembled on the center tube.


And here is how it looks with 116 film inserted onto the reel. I was fortunate that this was orthochromatic film, so I could load it under safelight. The trickiest part was making sure the pieces of the reel don't slide apart, since in this configuration they aren't locked together:


I hope whoever stumbles upon this post find this info useful!

How to Develop Found Film

I'm frequently searching thrift stores and camera shops for old equipment, and occasionally I'll find a camera with an exposed roll ...
