Caution should be taken concerning tightening of the take-up spool brake. If you only plan to play recently made rolls this if fine. However, many of us have rolls in our collections that are 60 or 70 years old, and the paper is very delicate. I have found that the best tension for the take-up spool brake is NONE AT ALL. On some old rolls, any tension at all on rewind will shred the edges of the paper. If you think the roll is too loose after rewinding, then after removing the roll from the spoolbox, hold the center of the roll gently in your left palm and rotate the right flange with your right hand, but not too tight. If the paper starts to squeak - that is too tight.

P.S. I just had another thought. I think I can see where having the feed spool brake TOO tight could cause this problem. At the beginning of a large roll the distance from the axis of the feed roll to the outside circumference is great giving you more leverage to overcome the resistance of the brake. However, at the end of the roll the lever becomes much shorter so that you have less mechanical advantage.
