The problem with router chamfering bits is that they tend to tear out end grain, so when chamfering the end of a board, I prefer to do the job by sanding. To guide the workpiece, I employ a scrap wood jig with a tall fence clamped at a 45° angle to the face of my stationary belt sander. After marking the desired chamfer on the board’s end, I then place the workpiece on edge against the fence. With the tool running, I ease the end against the belt, chamfering the long edge to the line. I then flip the workpiece and chamfer the opposite edge.
