Steel Square Handbook

By Ryan Phlean

You can memorize a rafter table. Or you can actually understand what it's telling you.Most carpenters learn the steel square the same way: watch someone else use it, copy the motions, hope the numbers work out. That gets you through a job, but it doesn't give you the confidence to solve a layout problem the book never covered - and it leaves you stuck the day your phone app glitches or the battery on your digital angle finder dies.
Steel Square Handbook teaches the square from the ground up, so the tool in your hand becomes something you can reason with, not just follow instructions from.
Inside, you'll learn how to: Read the body, tongue, and rafter tables with real fluency - not guessworkCalculate and cut common, hip, valley, and jack rafters with confidenceLay out stairs accurately, including winders and switchback stringersStep off rafter and stair lengths using the square alone, no calculator requiredCheck a square for accuracy and true one that's gone out of squareApply the same core principles across framing, roofing, and general layout workGrounded in the historical instruction of Hodgson and Siegele and rebuilt for the modern jobsite, this handbook walks you from squaring a single corner to laying out an entire roof system - one clear, deliberate chapter at a time. It doesn't ask you to abandon your laser level or framing app. It asks you to understand the geometry well enough that you're never dependent on them.
Carpenters, framers, and builders - apprentice or experienced - have used the steel square for over a century because it works, requires no batteries, and never loses a signal. This handbook is the reference that finally makes it make sense.Pick up your square, open this handbook, and start reading it instead of just following it.
