Is there a 8mm sound projector that can adjust the amount of film slack?

So that when the projector encounters damaged sprockets, the sound and image doesn't go all jittery / stuttering.

Just an idea; if you've got parts of a film where multiple sprockets are missing, you could use Cinekett S8 tape on those parts to restore the sprockets. Should work for at least a few runs I guess.

I got an experience a projector with plastic mechanism can reduce the jitter than metal mechanism (which is used mostly by higher lever projector). I am sure there will be downsides with this plastic parts but I am not sure what they are.

Some films that already got wrapped due to vinegar syndrome can be projected better in this type of projector while in higher level projector they were already unprojectable.

Projecting a film with damaged sprockets will only cause more damage. Most tape splicers for 8mm film cover 4 Sprocket holes and can be used without having to cut the film and if applied correctly will usually run through the projector o k. The majority of 8mm sound projectors have a loop restorer lever on the front of them. With some e.g. Eumig this lever has to be held down when loading the film. The more modern 16mm sound projectors have automatic loop restorers. I have never heard of a projector with a plastic mechanism! Ken Finch.😊

While automatic loop restorer mech seems to be quite a norm for 16mm projectors (late model at least) but there seems to be none-exist on Super8 counterparts. Why?

[Ken Finch]

Nantawat, I think the answer to that one is due to the layout of the film path and lack of space to fit the extra guide rollers required. With the larger gauges there is more space to fit the mechanism required. To my mind it is just one of the disadvantages of self threading projectors with everything enclosed. Ken Finch.😉

Ah...that makes total sense.😁

With only 18 frames between film gate to sound head it is already barely enough to smooth the film down before reaching audio part. it would be really challenging to add on anything else. Kodak must had prioritize the ease of sound editing (when we still have to make a physical "cut" to the film) above practicality. What a dud decision.

I imagne they had the idea for sound recording camera in mind when they designed the format and that was the maximum they wanted for cartridge loading and camera size.
