Ryuji,(posted 8397 days ago)I have found that sometimes with 36 exposure rolls, I will get a little bit of drag when I get to the middle or end of the roll. I think this is contributed to me forcing the film through the reels from the end (vs. SS reels you wind along). Where are you making the initial cut along the sprocket holes? Are there any jagged edges or sprocket holes? I could see where that might bind your film in the spool.
