TYPES AND USES - Continued
SLIDING T-BEVEL
The sliding T-bevel is made up of a slotted blade (1) and
a solid stock (2). The blade is adjustable so it can be set
to measure any angle. The T-bevel is used for testing
bevels and laying out angles.
BEVEL PROTRACTOR
The bevel protractor is made up of an adjustable blade
(1) and a graduated dial (2) which contains a vernier
scale. The bevel protractor is used to establish an angle
and determine its relationship to other surfaces. The
acute angle attachment (3) is used for measuring acute
angles accurately.
USING A CARPENTER’S SQUARE TO MARK A SQUARE LINE
1
To mark a square line, place the blade or tongue (1)
of the square against the side of the material with
the square tilted slightly so the blade or tongue of
the square extends across the work.
2
Mark a line across the work using a pencil or mark-
ing crayon.
USING A CARPENTER’S SQUARE TO LAY OUT STEPS
1 The following example shows proper square posi-
tion when marking cut lines for a series of steps
