This morning I received an email asking me: "why would a timber framer want such a tool?"

Here is my response to this:

Understanding how to read single beam drawings and how to do the layout of
roof timbers for manual processing is very important to today's timber
framer.

This layout can be done using a Dietrich's Alpha protractor square to easily
and accurately copy the information given in the shop drawings onto the
timbers to create hip, valley and jack rafter cuts.

The Dietrich's Alpha protractor square can help us to apply the traditional
use of drawings and angles. With marks at every 1/2 degree and in imperial
units (inches not millimeters), it can transfer angles to large stock with a
high degree of accuracy. Timber framers using the "Hawkindale" angles, as
many American companies do, find the Dietrich's protractor square especially
useful.

Timber framers who don't use the "Hawkindale" angles also find the
protractor square useful to layout the roof system, as well.

Please consider adding this fine tool to your shop or toolbox.
