Hello, and welcome to Joe Shows How! In this week’s video, I share five ways to use a speed square, which is also commonly called a rafter square or layout square. If you’re not familiar with a speed square, don’t be fooled by its simple design; it’s an indispensable tool for both carpentry and woodworking projects.
Speed squares are available in 6-in. and 12-in. sizes. The smaller size is popular because it fits neatly into a tool belt, but the larger square is more useful when working on wider boards and timbers. Regardless of what size you get, here are five essential tips for using a speed square:
Marking 45- and 90-degree lines
As a protractor to mark angled lines between zero and 90 degrees
To accurately draw lines parallel to the edge of the board using the marking notches
To quickly find the exact center of a board without having to measure
As a circular saw guide: hold the square in place and guide the saw along the edge of the square
I hope you find these tips helpful. And if you don’t own a speed square, go get one. You won’t regret it!
