Well..I guess that the edge looks fairly far away from the top rail as it is and my thought was that routering might make it look even worse. I would like to narrow the gap a bit by maybe adding a touch like a board nailed perpendicular to the ends. I'm not sure if they make a finish piece shaped sort of like an angle that can be nailed down. I'm just not sure what to do. The guy who finished it angled the boards around the upright top piece and it just looks bad to me.
