NC Cams - coincidence you should mention Kodak. There is a current forum of film technicians, I think, looking for steel film, that used to be made by Kodak. Use it for sprocket registration in film projectors , as far as I could make out.
But your mention of bandsaws prompts other ideas. Mine is driven by the 1/2" blade running on the outside of a v-belt . With a 6" wheel and only about 5" length of blade in contact with it, there's no way I can make it slip.
Interesting thought - thanks.
