Bulk Loader

[Attila]

I did start to use bulk loader to get cheaper rolls from b&w films, I did worry about scratches on emulsion if I use old cartridges. I did clean loader and each cartridges with compressed air. Works great, no worry.

Yes, cleanliness is the word. A tiny particle of grit will get you tram lines , it occurred to me. Also make sure the work bench is clean too. Of course the loader must be loaded in TOTAL darkness.

Another trick to prevent scratches is to load the spool outside the cassette, and then put it in and snap on the cap once it is fully wound. It is a bit more of a hassle, as it must be done in a darkroom or changing bag, but it saves the film one trip through the felt.

Likewise, if you bulk load in the darkroom direct from the bulk spool to the cassette spool, you can save a trip through the felt in the bulk loader as well, so TWO less trips through felt.

Switch to labyrinth cassettes, and you can cut out the last two felt passes (when the film is in the camera) - and have no felt contact at all.

Do you use compressed air from a can?
