10.4 Rabbeting
A rabbet is a groove cut along the edge of a
board. See Figure 10-4. The width and thickness
of the wood to be rabbeted depends upon the
width and length of the rabbet. However, never
rabbet a piece of wood less than 12” long.
Figure 10-4
Note: The knives must be extended beyond the
cutterhead by 1/32”. See the Setting Knives for
Rabbeting and Nicks section on page 20 for this
procedure.
A rabbet cut requires
removal of the guard. Use
extreme caution and keep hands clear of
cutterhead.
Always re-install guard
immediately after rabbeting operation is
completed.
Use push blocks to rabbet cut whenever
possible. The rabbeting capacity is 1/2”.
1. Disconnect jointer from power source.
2. Set fence for desired width of rabbet.
3. Check width of the rabbet by measuring the
distance from the end of a knife in the
cutterhead to the fence.
4. Re-connect power. It is easier and safer to
take a series of shallow cuts. Lower the
infeed table 1/32” at a time and make
successive cuts until the desired depth of
rabbet has been obtained. See Figure 10-4.
10.5 Jointing short or thin work
When jointing short or thin work pieces, use a
push block to eliminate all danger to the hands.
Two push blocks are shipped with your jointer.
You can also make your own easily from scrap
material. Examples are shown in Figure 10-5.

10.6 Jointing warped surfaces
If the wood to be jointed is cupped or bowed,
place the concave side down, and take light cuts
until the surface is flat.
Avoid forcing such material down against the
table – excessive pressure will spring it while
passing the knives, and it will spring back and
remain curved after the cut is completed.
