I learned to roll film onto the Nikkor (and other) SS reels without using the clip. It's much easier. You just slide the end of the film into the center of the reel and start winding.
Does this method work on reels that have a center clip? wouldn't the clip get in the way of proper insertion? Without looking at my reels, I guess it's likely that the little wire clip is only brazed to one of the center pins of the reel.
