EasyCoper Tool Co. has done it again - only this time, cut baseboards not crown molding with the BaseCoper. Simply miter the baseboard in the normal manner. Place the BaseCoper on top of the baseboard allowing the molding to be visible through the opening of the BaseCoper. Secure the BaseCoper to the work piece with a clamp. Extend the BaseCoper beyond the edge of the work surface and use your jig saw and the manufacturer's recommended blade to make relief cuts on the profile of the molding. The BaseCoper provides a flat surface for your jig saw to ride on and keeps it at the correct angle. For baseboards taller than 5-1/2 you will need to shift the BaseCoper from one side to the other to complete the full height of the baseboard. A larger clamp may be necessary. Made in USA.
