Cutting baseboard to length in old homes can be challenging. The floors are always off level, and, most of the time, the casement moldings around all the doors are out of plumb too. Rarely is the cut angle 90 degrees where the baseboard meets the casing.

This simple jig allows you to scribe the angle cut to the baseboard for a tight joint. It’s easy to make on site by notching a piece of scrap. Line it up against the casing, as shown in the photos here. No angle finders. No math. Just fast and simple.
