I can not match the chair rail cut from the stair way which is approximatly at a 50 deg. Angle up the stair way to the top of hallway on an outside corner. The piece of chair rail that comes up from the stair way is wider after I cut it because of the angle that I have to have coming up the stairs than the piece that intersects at the outside corner from the hallway up stairs, just mitering it at a 45 deg does not match.
