F. RABBETING
A rabbet is a groove cut along the edge of a
board. It is usually made to accept another board
to form a strong, simple joint. Note: The maxi-
mum rabbet depth is
1
⁄
2
".
1.
Remove the cutterhead guard.
2.
Loosen the fence and slide it to the rabbeting
edge. Set the fence to the desired width of
the rabbet and lock down. For small rabbets,
remove the fence sliding locking lever and re-
insert it in the rear fence hole on the fence
base.
3.
Inspect stock for soundness and grain direc-
tion.
4.
Place stock on the infeed table and rabbet
table with the edge to be rabbeted firmly
against the fence.
5.
Slowly and evenly feed stock through the
cutterhead. Using the
1
⁄
16
" rule, it will take six
passes to achieve a common
3
⁄
8
" rabbet. See
Figure 27.
6.
Replace the guard when finished with rab-
beting operations.

ing.
E. SURFACE PLANING
The purpose of planing on a jointer is to produce
a flat – not necessarily ''finished'' – surface. The
theory behind this is that once you have one flat
surface on a board, it can then more readily be
milled to precise, final dimensions on a thickness
planer.
1.
Inspect your lumber for soundness and grain
direction.
2.
If the stock is cupped (warped), place the
concave side down and slowly feed it
through the cutterhead. See Figure 26.
3.
Inspect your results. Most likely, many pass-
es will be necessary before your lumber has
a flat surface.
4.
If the stock has large or loose knots, consid-
er finding another workpiece. Knots in a
workpiece can be dangerous to the operator,
as well as destructive to equipment.

X. OPERATIONS (CONTINUED)
This section assumes that all necessary
operational adjustments to the jointer have
been made as discussed in the previous
section.
