Euclid’s Door




By George Walker and Jim Tolpin, Illustrated by Keith Mitchell and Barb Walker.

Open a historic tool chest and you’ll often see many tools that were user made. In general these user made tools are what we call “tools of the imagination”. These are used for design and layout, such as straightedges and squares. They all have a strong linkage to geometry and for that reason contain the lessons of geometry that was an important part of our craft.







Euclid’s Door walks you through the building (and the geometry) of a complete set of 18 layout and design tools. You will learn the lessons our ancestors passed down as well as build a set of accurate and functional tools.

The cloth-covered hardbound 115-page book is printed in the USA. Price includes Shipping
