I’ve done some guitar building and a lot of woodwork and model building. Personally I would be a little leery about tackling soundboard braces with a sanding disk chucked in a drill. Things like that can get away from you, and especially the inexperienced, and make a quick mess of a project. I would suggest Rick’s method or use a small spokeshave like I do. These are the spokeshaves I have and they work beautifully if properly sharpened.

If you haven’t done much sharpening use a diamond lap (http://www.rockler.com/product.cfm?page=2414&filter=diamond%20sharpener) working from course to the finest to sharpen, then use a spiral-sewn cotton buff (http://www.pjtool.com/spiralsewnbuffingwheels.aspx) charged with black emery polishing compound (http://www.pjtool.com/search.aspx?find=rouge&page=2) on a small electric grinder or an electric drill to buff the blade edge to razor sharpness. ALWAYS run the buff direction away from the sharp edge or the edge will catch and knock the blade from your hands. You can quickly prepare a razor sharp edge using this method. Test the blade by shaving the hair on your arm. The cotton buff and polishing compound can usually be bought inexpensively at a good local hardware store.
