Description

Extracted from a 1923 edition of Audel's Carpenters and Builders Guide #1, this booklet describes many uses of the steel square with the main focus on how to calculate and cut rafters, including hip, jack, valley, cripple and common rafters.

When this was written, a carpenter's square was the primary layout tool in a carpenter's toolbox, used to solve numerous geometric problems that we use a calculator for today.

Softcover, saddle stitched, 5" × 7", 56 pages. Reprinted in 2001 as part of our Classic Reprint Series.
