Andre Roubo's Try Square
PDF Download: Full PDF plans and templates for Andre Roubo's try square.
Andre Roubo's 18th-century plans for a try square – which he called a "triangle" – is one of the most beautiful pieces of workshop equipment we've ever seen.
Editor Christopher Schwarz built six of the squares and published a short article on them in the February 2010 issue of Popular Woodworking. And while many woodworkers will be able to build the square using the instructions in the magazine, we often receive requests for additional information.
So Schwarz put together a package of detailed information on the square, which is available here for instant download. The download includes:
1. The two-page Arts & Mysteries column from the February 2010 issue that explains the reasoning behind the square, its special features, the cutting list and construction drawing.
2. A six-page article that covers the construction process in complete detail, from selecting the stock, to truing the square and finishing it.
3. A page of full-size profiles of the square's cavetto, ogee and handle shapes to make it easy for you to stick the pattern to the wood and cut it out.
4. A SketchUp file of the original square that you can study or modify to suit your needs.
Why build this square? Though the blade is more than 13-1/2" long, the whole square weighs only 7 ounces. Its stock is narrower than that of a traditional rosewood and brass square, and it is surprisingly comfortable to hold, carry and use.
The cavetto in the stock and the ogee shape on the blade adds a little flair to a usually rectilinear (read: boring) tool. Plus, they are a blast to make. All of the elements of construction required great care, but because the tool is so simple, it never gets tedious.

Similar Woodsmith Plans
The United States Customary System of Units (USCS or USC), more commonly referred to as the English or Imperial system, is the standard set of units for our plans. It uses inches and feet for measurement. This is the one you probably want if you are in the United States, and it is the one we have traditionally offered on this website.
The International System of Units (SI), more commonly referred to as the metric system, is the alternative set of units that we have available for some of our plans. It uses millimeters, centimeters, and meters for measurement. This is the one you probably want if you are outside the United States. These plans are provided by our business partner, Australian Woodsmith, and are based on the original Woodsmith plan. However, dimensions and other elements of the plan may vary between the metric and standard versions. Be sure to double-check the plan before building.
All of the information that you need to build our plans can be found in the standard plan. However, if you want even more granular detail to make your job easier, you should consider our premium plans. These come with additional shop diagrams that we drew when creating the prototypes. Shop drawings are not available for every plan.
