SOMETIMES IT WOULD BE AN ADVANTAGE to be able to fine-sand a bunch of small parts on a disk sander and not have to change out the disks from coarse or medium to fine. One solution to the problem is to cut out the center of a large disk of coarse paper to accommodate a smaller-diameter disk of fine sandpaper. Cut out the proper sized area from the back of the large disk (possibly the size of a small disk – depending on the small disk available), and attach the small disk to the middle of the sander with the large disk around the outside. This, in effect, gives you two grades of paper on the same sanding disk. Be really frugal and save the center of the large disk that you cut out for the same sort of setup on some other job.
