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.
Position the fence (move it forward) to

expose only the amount of cutterhead
required.
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).
Figure 22 – Surfacing
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.
Beveling
Beveling an edge is the same operation as edge
jointing, except that the fence is tilted to a
specified angle.
Make certain material being beveled is over

12 inches long, more than 1/4 inch thick and
1 inch wide.
To bevel:
1. Use a bevel gauge to determine the desired
angle. Then set the fence to the same angle.
2. Inspect stock for soundness and grain
direction (refer to Direction of Grain).
3. Set the infeed
approximately 1/16.
4. If the board is bowed (curved), place the
concave edge down on the infeed table.
5. Feed the stock through the cutterhead,
making sure the face of the stock is
completely flat against the fence and the
edge is making solid contact on the infeed
and outfeed tables (Figure 23).
For wood wider than 3 inches – hold with
fingers close together near the top of the
stock, lapping over the board and extending
over the fence.
For wood less than 3 inches wide – use
beveled push blocks and apply pressure
toward the fence. Keep fingers near top of
push block.
Several passes may be required to achieve the
full bevel.
