Among all
the tools used by carpenter there is, perhaps, non so
useful, simple and indispensible as the modern Steel
Square. There is not a tool that maybe so readily
applied to the quick solution of the many difficult
problems of laying out work as Steel Square.
There is not a tool
that maybe so readily applied to the quick solution of the many
difficult problems of laying out work as Steel Square. In the
hands of one who knows how to use it the square becomes a simple
calculating device of the most wonderful capacity.
There is a feeling among
carpenters, that one must have a knowledge of higher mathematics
in order to be able to use a Steel Square with all its
complicated markings, figures and tables. This is not true.
With its numerous scales and figures there is nothing about it
that is complicated.
The understanding of a very few
simple rules governing application of this Square will enable
the carpenter:
To easy and quickly determine the
length of any Common, Hip, Valley or Jack Rafter for any Pitch
of Roof. To make the proper Top and Bottom Cuts as well as
Side or Cheek Cuts for any Rafter.
