Hello, I give that little trick to your attention. I use a little 4 ' piece of an old S&S rail, and glue on it a piece of the wonderful 3M "Microfinishing film" (wich is a first choice for voicing and fine hammer filing/fitting). Then I have a file to correct a flange witch would need too much papering. I suggest you to try this film, graduation in microns, correspondence from 150 to 4000 sanding paper approx, the film is rigid and ideal for hammer work. sold in self-adhesive or sheets. The 8microns quality is smooth as a baby skin ! good for the rollers too. regards.
