While doing some work I had several small pieces to be finished with sandpaper. They were so small and of such a shape that it was impossible to do the work by hand. Not having a sanding machine, I used a disk talking machine for the purpose. I placed a sheet of sandpaper over the disk and fastened it to the felt at the corners with pins. The machine was then set going at its highest rate of speed, and the articles were smoothed by holding them on the disk. - Contributed by Fred S. Barnard, Los Angeles, Cal.
