I have a 6 panel black walnut door. The stripper thought it was from the late 1700's to early 1800's (different from most of my other doors in my 1825 house). Prior to 1914 the hinges were moved to the other side of the door and the 1st side broke. That side of the door was painted so they replaced the black walnut with maple (about a 4" x5" flat triangle). I'm going to finish the whole door with Waterlox - no paint. How do I stain that repaired section so it may look a little closer in color to the black walnut? Is it a losing battle? Any other words of wisdom?
