Novice woodworker here, I'm putting together a few pieces of mid-century modern furniture and need to create a half-round profile on the edge. Previously, I have used a quarter round to mill the top and bottom of the workpiece leaving a small flat in the center for the bearing to ride on. This worked OK, but required finessing with sandpaper to make it appear as one continuance arc.
Is there a better technique that I haven't yet discovered? The work piece has multiple complex curves, so setting up a fence for a non-bearing guided router bit is fairly impossible.
