USING A TRY SQUARE
To check a square joint, place the stock (I) 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
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.
Loosen locking nut (1) and adjust blade (2) to mea-
sure a desired angle using protractor (3). Tighten
locking nut (1).
The angle may now be laid out by extending the
blade across the board with the stock (4) held firmly
against the edge.
