16mm bolex scratches /or scan problems?

[Matteo BONADDIO]

I can't seem to identify why or where theses straight lines are coming from. Theses lines are not on the entire rolls, they come and go.

I've completely cleaned my bolex multiple times.

 

Any ideas ?

Vertical scratches are usually something in the camera gate or loop path.

Processing scratches usually move left-right and can be a piece of debris trapped in a squeegee for example.

If this was scanned on a Spirit or Scannity there may be a chance that there is some dirt in the aperture slit on the scanner.

Cleaned the Bolex more than once, still happening.

Thinking the loop formers are slightly scratching the film when being shot. The straight line come and go during the same roll. Meaning that during shooting, the loops are slightly moving up and down, scratching the film as it moves along.

Ever heard of it ? Sound possible ?

No. In case everything is adjusted correctly and functions properly the open loop formers are out of the way of the automatically threaded film. You can, of course, provoke scratches by lacing the film by hand, making one loop or both too wide or too tight.

There are people who force the lid on the housing against the resistance of the loop former lever pointing downwards and or a/the film guide/s around the sprocket rollers open. With the spring-loaded guides and automatic opening loop formers from serial nr. 178471 on that problem went away until the introduction of the film guides retaining fork of the magazine models. Guides and formers must be unbent, adjusted, free from bruises. Older examples tend to have the chromium plating flaking off the loop formers.

I can only recommend to follow the instructions Paillard gave, with one exception. The film’s head is better cut to the form of an arrow precisely the way Paillard discouraged to do. Automatic threading then always works faultlessly. Most built-in cutters are blunt anyway. A pair of scissors in the camera case is worth gold, especially for polyester-base film.
