Direction of Grain
Avoid feeding work into the jointer against the
grain (Figure 20).

This may result in chipped and splintered edges.
Feed
with the grain to obtain a smooth surface,
as shown in Figure 21.

Edge Jointing
Jointing (or edging) is the process of creating a
finished, flat
edge surface that is suitable for
joinery or finishing (Figure 22). It is also a
necessary step prior to ripping stock to width on
a table saw.
! 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.
When workpiece is twice the
length of the jointer infeed or outfeed table
use an infeed or outfeed support.
To edge:
1. Make sure the fence is set to 90°. Double
check it with a square.
2. Inspect stock for soundness and grain
direction (refer to Direction of Grain on
previous page).
Figure 22
3. If the board is bowed (curved), place the
concave edge down on the infeed table.
4. Set the infeed table for a cut of approx-
imately 1/16 inch.
5. Hold the stock firmly against the fence and
table, feed the stock slowly and evenly over
the cutterhead.
