Hi Peggy, If the paper does scratch, just rub it on a piece of steel or concrete to dull it up a little. I have used sandpaper (600-1200 grit), but like Bernie, I us steel wool. The only difference is I use mineral spirits as a lubricant. Them clean them again. If you get a set of let down keys, you mike can make you a winder using a ratchet and a 7/16 deep socket. If you do a yahoo search for clock mainspring winder videos, you will get some easy to make ideas.
