(shown above) takes a minimal amount of material, skill and time to build. Yet it contains the basic features needed to experience its potential usefulness.

The construction is self-evident, though a few aspects deserve comment. It's important that the stop pieces be positioned at a true 45° angle. This needs to be laid out and checked carefully with a miter square or sliding bevel you know is accurate. (In my next column I'll show you how to do this easily with a compass and a scrap of wood.) Using a pair of stops allows planing from both directions (a useful feature), and the placement

shown allows the stops to reinforce each other against the planing stresses.

While this version can be satisfactory, there are drawbacks in the long term. First, the manner in which the two base elements are assembled provides for unequal moisture movement from the opposite faces of each

piece. This can lead to the appliance going out of true. Careful material selection (quar-tersawn and straight-grain) can minimize this. And, within reason, it can be disassembled and the pieces re-trued, from time to time. There are other alternative forms of construction that address these issues.
