Layout Squares
You won’t realize how useful these squares can be around the shop until you have a few at hand.
For any square to be of use as a layout or marking tool it must, of course, be square. The most dimensionally stable material to use for this project would be a manufactured sheet goods such as MDF or Baltic Birch plywood.
This version is made of three different species: the arm is wenge, the edge guide is makore and the straight surfaces have been edge-banded with quarter-sawn white oak. Not only does the while oak provide a durable long lasting guide surface, but it also contrasts nicely with the other two species.
Square Stable Stock
While you can choose from a wide range of wood to use in your square, it’s important to select dimensionally stable wood, preferably quarter-sawn, else your square may be, seasonally out-of-square. When milling your stock accuracy is important – you want all of the parts to be flat and square.
It is easier, as well as safer, to make two squares at once – this lets you work with larger pieces when preparing the initial stock on the jointer and thickness planer. The dimensions in the materials list reflect this. Of course, you can easily modify the dimensions to suit the kind of work you do. You might want to make one large square for use on cabinetry and sheet goods, and a smaller one that would be more manageable on your workbench.
These layout squares are sure to be some of the most useful accessories in your shop. Make some in several lengths and you’ll always find a use for them, from laying out full size drawings to a fast and accurate clamp down fence for your router.
