To the users of the Alden 74 or Watson 100, when you are finished loading cassettes and have closed the loading chamber door, do you leave the light trap closed or do you open it so it doesn't kink the film?
Both the Alden and Watson loaders use a light trap slot that opens when you load a cassette. When you are finished loading the cassette, you close the trap to prevent light from exposing the film in the chamber. The question is, if you store the loader with the trap closed, it can lead to a kink in the film between the film chamber and the loading chamber. The loading chamber door provides a fairly good seal and in videos I've watched users doing it both ways.
I wouldn't over think it. The potential kink is so close to the light struck tail of film it wouldn't matter. I didn't mean to be flippant. I've never heard of this being a problem.
I close the light trap with both an Alden 74 and a Watson 100. The resulting kink is not a problem loading the film in either an LTM Leica or a Nikon F, both of which some people find difficult to load.
I would never store my loaders with the gate open. Doing so would mean that if the cover is opened (by mistake, or accidentally through handling) the film till in the loader will be fogged on the outer layer, sprocket fogged on a couple more layers, and edge fogged right to the core.

So in the video he leaves the trap door open for storage! Closing the door does NOT kink the film. My biggest problem seems to be leaving the door closed when loading the film cassette which always ends up scratching the film. And whats with using packing tape and cutting it in half. For me the packing tape gets stuck to everything (including me). I just use Scotch tape from the dispenser. I guess anybody can make a video. I did like all the hand pantomimes. madNbad you did good asking the question here instead of relying on a youtube video.
Usually with the light trap open. That way the door does not flop around, as you know there is no mechanism (other than opening the light trap) to keep the door closed. But it really makes no difference either way.
BTW Alden is the best. Still using the 200ft model I got in 1974.
