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

This may result in chipped and splintered edges.
Feed with t he grain to o btai n a smooth s urface,
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 t hick, 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 so undness 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 agai nst the fence a nd
table, feed the stock slowly and evenly over
the cutterhead.
