Dado Cutting - Grizzly G0493 Owner's Manual

dado cutting

Commonly used in furniture joinery, a dado is a
straight channel cut in the face of the workpiece.
typically, dadoes can be cut using either a dedi-
cated dado blade or a standard saw blade. figure

made with a dado blade.

important: a dado blade cannot be used with
this machine; therefore, all dadoes cut with this
machine must be done with a standard blade.
cutting dadoes with standard blade
a ripping blade (described on page 41) is typically
the best blade to use for cutting dadoes when
using a standard blade, because it removes saw-
dust very efficiently.
to use a standard saw blade to cut dadoes:
1. disConneCt saW FroM poWer!
2. ensure that the riving knife and standard table
insert are installed and properly adjusted. do
not use the standard insert if it has lost the
zero clearance feature by modification; if so,
you must install the optional Model t21879.
3. Mark the width of the dado cut on the
workpiece. include marks on the edge of the
workpiece so the cut path can be aligned
when the workpiece is lying on the table.
4.
raise the blade up to the desired depth of cut
(depth of dado channel desired).

5.
set up the saw for the type of cut you need to
make, depending on if it is a rip cut.
6.

as shown in figure 97.
