Pry or cut off a piece of the molding you want to copy. If it's caked with paint, strip it down to bare wood. Take a piece of wood slightly longer than you need and cut it down on the table saw to match the height and thickness of the molding you're copying. Trace the profile of the original onto the end of this blank. If the wood will be stained, choose a blank of the same species as the original.
