Surface treatment
The purpose of planing on a jointer is to produce one flat
surface (Figure 20). The other side can then be milled to
precise, final dimensions on a thickness planer resulting
in a board that is smooth and flat on both sides and
each side parallel to the other.

Step 1: If the wood to be jointed is cupped or bowed,
place the concave side down, and take light
cuts until the surface is flat.
Step 2: Never surface pieces shorter than 12 inches or
thinner than 3/8 inch without the use of a spe-
cial work holding fixture.
Step 3: Never surface pieces thinner than 3 inches
without the use of a push block.
Step 4: Cuts of approximately 1/16“ at a time are recom-
mended, which provides for better control over
the material being surfaced. More passes can
then be made to reach the desired depth.
Direction of grain
Fig. 21: Work against the grain direction.
The planer against the grainmay result in chipped and
splintered edges. Feed with the grain to obtain a smooth
surface, as shown in Figure 22.

8.6 Thicknessing
Thicknessing (or edging) is the process of creating a fi-
nished, flat edge surface that is suitable for joinery or fi-
nishing (Figure 23). It is also a necessary step prior to
ripping stock to width on a table saw.
Fig. 23: Stopper for fine boards
Never edge a board that is less than 3 inches wide, less
than 1/4 inch thick, or 12 inches long, without using a
push block.
When edging wood wider than 3 inches lap the fingers
over the top of the wood, extending them back over the
fence such that they will act as a stop for the hands in
the event of a kickback.
Position the fence (move forward) to expose only the
amount of cutter head required.
When workpiece is twice the length of the jointer infeed
or outfeed table use an infeed or outfeed support.
Tips and recommendations
Avoid feeding work into the planer against the
grain!
