Rabbeting
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.
A rabbet is a groove cut along the edge of a
board. See Figure 42. 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.
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. NOTE: The knives
must be extended beyond the cutterhead by
1/32”. (see “Replacing Knives in the
Cutterhead” for this procedure).
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 42.
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 43.
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.
Beveling
To cut a bevel, lock the fence at the required
angle and run the work piece across the knives
while keeping it firmly against the fence and
tables. Several passes may be necessary to
achieve the desired result.
