One of the problems I have on my Delta SA180 is getting a convex edge that can be completely touched up with one pass - I have to make about three passes with each grit and blend the passes with one another. I'm guessing I don't take off enough metal on the back portion of the edge and am not using enough pressure. I'm wary of using too much pressure and rounding the edge however. I really need a tutor <img src="/ubbthreads/images/graemlins/smile.gif" alt="" /> Alternatively, some good vids of your techniques (which really show how much belt deflection you should be getting to get cetain results) would be helpful.
