CH Hanson Expert Guide to Roof Construction and Framing

Features & Applications:

This CH Hanson expert guide to roof construction and framing is a well-written, easy to understand and filled with detailed example, and it wasn't that long before we had a grasp on the basics of the Pivot Square. Even though this is no speed square, there are similarities, and we can say with confidence that the book provided with the Pivot Square completely blows away the books that come with both the Swanson and the Johnson Speed squares.

The book also describes how the Pivot Square can assist with stair layout. With the help of a framing square (as instructed), we had no problem following the directions and making two perfect stair stringers. As detailed in the book, the Pivot Square method prevents the problem of cumulative error that we've seen happen over and over again.
