Speed Square Guide: How to Measure, Mark, and Cut Accurate Angles for Woodworking and Framing

By Grandpa Arnold

Master One of the Most Useful Tools in Woodworking

The speed square looks like a simple triangle. Most beginners use it once or twice to draw a quick line, then set it aside. What they don't realize is that this small tool - in the hands of someone who truly understands it - is one of the most capable layout instruments in the entire workshop.

Professional carpenters reach for it constantly. They use it to mark precise angles, guide circular saw cuts, check framing accuracy, lay out roof rafters, and solve layout problems in seconds. The speed square does not just draw lines. It thinks with you on the job.

This book was written to close the gap between owning a speed square and actually knowing how to use one. Every chapter focuses on practical, real-world technique. No filler, no theory for its own sake - just clear explanations, step-by-step walkthroughs, and detailed diagrams that show exactly what your hands should be doing and why.

What you will learn:

Every part of the speed square and what it actually does in practiceHow to mark accurate 90-degree and 45-degree cuts quickly and consistentlyHow to use the speed square as a guide for circular saws and handsawsHow to check squareness and alignment at every stage of a projectHow to find the center of a board in seconds without complicated mathHow to mark repeated layout lines for framing and construction workHow to measure roof pitch and lay out common rafters on siteHow to mark and cut plumb cuts, seat cuts, and birdsmouth joints

The chapters are structured to build on each other. You start with the fundamentals of grip, seating, and basic marking, then move through cutting guides, squareness checks, and repeat layouts, before finishing with full roof rafter layout and installation. Each concept is supported by clear diagrams drawn specifically to show the technique - not just the tool.

This book is for beginners who want to build real skills, for DIY builders who are tired of guessing, and for anyone who has looked at a speed square and suspected it could do more than they were getting out of it.

It can. This book shows you how.
