Yep! I've done it! All it takes is for the film edge to buckle so that the film jumps its track and collapses onto the previous coil. To avoid this, the film must be squeezed into a curve: not too flat, or it won't fit between the rails; and not pulled too tight while winding, as that will buckle the edge into a "crinkle." Once that happens, the remaining film after the "crinkle" will not wind on properly. Pinch the film into a curve, and wind with just a light tension. That's the key.
When it's going well, the film edges make a whispering sound as they find their way onto the reel. Wind-wind, "Shhhh-Shhhh" wind-wind-wind, "shhhh-shhhh." When it's going wrong, it's wind-wind, "crackle crinkle." Then we must back up, correct the error, and finish loading.
Stopping every so often to jiggle the film back and forth very slightly will tell you if you are doing it right. When you slip it back and forward, it should move freely. If it feels stuck, back up and re-do it more carefully.
