With a wee bit more thought, this step is quite easy, if you have a table belt sander (as I do, but it didn't occur to me). Just take it through the grits, 320, 600, using the t-square and table. Much more reliable than hand work with file and stone - it's easy to get off a straight line with hand/arm motions. Regards, Fred Sturm University of New Mexico fssturm at unm.edu
