Operation
Setting Knives for Rabbeting and Nicks
To position the knives for rabbet cuts, take a shop
scale with 1/32" graduations and place it against the
end of the cutterhead. Slide the knife out until it is at
the 1/32" mark on the scale; that is, the knife will now
be 1/32" beyond the edge of the cutterhead. The gib
should remain in normal
position, even with the edge of the cutterhead.
(Figure 43). This adjustment will ensure that the knife
clears the end of the gib and cutterhead, and has
good contact with the workpiece. (See the
Rabbeting section on page 17 for further
information.)
Note: This will also correct for small nicks without
requiring replacement of blades.
Determining Correct Table Height
When you receive the jointer, the knives have been
pre-set at the factory. However, the height and
parallelism of the knives with the outfeed table
should be checked, and any needed adjustments
made, before putting the jointer into operation.
The outfeed table and cutterhead knives are
correctly adjusted when all three blades are
parallel to the outfeed table and all three blades
are set at the same height in the cutterhead.
Outfeed table too high – If the outfeed table is too
high, a curved finished surface results (Figure 44).
Outfeed table too low – If the outfeed table is too
low, the work will have a gouge, or snipe, at the
end of the cut (Figure 45).
Outfeed table at correct setting – Figure 46
illustrates the correct setting of outfeed table level
with the knives. The workpiece will rest firmly on
both tables with no open space under the finished
cut.
