USING A TRY SQUARE
To check a square joint, place the stock (1)
against a horizontal section and the blade (2)
against a vertical section. Light must not be
seen around blade edge. If light is seen, the
work is not square.
USING A SLIDING T-BEVEL SQUARE
Loosen locking nut (1) and adjust blade (2) to
measure a desired angle using protractor (3).
Tighten locking nut (1).
To check the end of a board, place stock on
vertical edge and extend blade over the end.
Light must not be seen around blade edge. If
light is seen, the work is not square.
The angle may now be laid out by extending the
blade across the board with the stock (4) held
firmly against the edge.
