Hans Borjes said:One aspect has not been mentioned so far. I am using Jobo 1520 tank and reel and 120 films. In the beginning I placed the emulsion to the innner side of the reel with the consequence that the (sharp!) inner end of the film scratched on the emulsion side of one frame.

Leon said:I find 120 film to be a complete nightmare in hot and humid conditions. I always use the 2 films on a reel method too, so this makes it even more difficult, that along with only using dark-bags to load film and having naturally sweaty hands.

Donald Qualls said:I've mentioned it, too, at various times. I don't find the aligment particularly critical, perhaps because I hit on a method very early on that makes it automatic. When I get the first roll fully loaded, I push it another half turn or so around the reel, then push the second roll in behind it; with something like 6-8 inches of the second film already in the spiral, it's automatically aligned very accurately and all I have to do is stick the head of roll 2 to the tail of roll 1 and finish "walking" the film in.
Now, if you try to load 2x120 in a *stainless* 220 reel, you'll be looking at some critical alignment and probalby need to make yourself a jig...
On negative processing this is most likely not an issue. On reversal processing with the modern T grain films as well. But on reversal processing of classic films this phenomenon becomes apparent.poutnik said:Hans, I'm using the same jobo tank and reels and have never had such a problem. I always load the emulsion side inwards, feeding the film onto the reel while unrolling from the spool, always trying to hold only the edges of the film and not touch the surface. And never have I had any scratches on the film that I could attribute to the reels...
Stan160 said:I can't load 120 film in a changing bag without a lot of frustration. It always gets stuck halfway so many times that by the time I've loaded it there are usually scratches on the film. Only been using 120 for the last few weeks so maybe it's the heat and humidity but the film gets so sticky it won't move around the spiral, one got so bad that the unloaded end of the film stuck to itself and ruined several frames.
Hans Borjes said:Would be interesting to know how this is handled by the other slide developers.
Leon said:sorry to hear that Stan. if you do need to use your changing bag in the future, try the cooling methods I describe, they have solved the problem for me.
poutnik said:...
The problem was not the wetness of the film (or the spiral - I even loaded a film on not-fully-dry spiral from previous development run, and the film went in OK), but instead the leading part of the film going slightly up or down and hitting the ribs
