So im new to collecting antique projectors, and my main issue with my Bell and Howell Autoload 8mm is that after a while, during a film, its starts making a loud clicking noise and the film begins to bounce vigorously. If anyone has the solution i'd be grateful if you could share, thank you.

Hello Javier,

It appears your projector is not holding loop and the reason can be one or a combination of issues, including film.

Can you tell us the brand and model of your projector?

Regards

Jon

Hello Jon,
Thanx for replying! The brand is Bell and Howell. Its a super 8 and its a 346 model.

Hi Javier, I would be looking for bad joins in film or where the holes are along the edge of film if any are broken.

Now more I think of it, some projectors, well maybe most, not sure about your model, they have a lever one can press down while film is playing that clears film sticking. Should find it at top of project above where you feed film, most likely plastic button to press. My Sankyo and Titan have it.

Also plenty of videos on You Tube where one can learn ( as did I, I knew not much about 8mm films except from what my late father taught me as a kid, rest I have learnt from you tube and the nice people on here)

Good luck

Phil

Phil,
Interesting that you say that because one of the films that has the issue does have broken edges but only in the beginning. Does that affect the rest of the film?

It can cause the loop to be formed incorrectly, it would run OK for a bit and if a poorly made splice goes though that could cause the loop to be lost.

Yes, once one of the loops (upper or lower) is lost the film will continue to play , incorrectly. The loops give the freedom of play that allows for the intermittant movement of the pull down claw to register a continuously, stable picture.

The lower loop also smooths out the intermittent motion of the film before it reaches the sound heads.
