I want to make some spacers to use 120 film in a camera designed for 116 film. If anyone has a 116 spool, I would appreciate it if you could measure the length and let me know.
I think 616 is just slightly shorter than 116 but not by enough to matter, The diameter of 616 is smaller than 116 though.
I did think about using a 616 spool for take up and pack out the supply reel but it's not a big deal to make some spacers. Only one of them needs to engage with the winder so three of them are very simple.
