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

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.
