Surface Planing
One of the most common operations on the join- ter is surface planing. Surface planing produces one flat surface on a piece of stock as shown in Figure 35.
After being surface planed, the stock is usually run through a thickness planer so the board thickness is consistent from one end to the other.
Figure 36 shows an example of an operator using the jointer to surface plane a piece of wood stock. Notice that the operator’s body is not directly behind the stock and that the oper- ator is using push blocks to feed the board.
To perform a surface planing operation:
1.Make sure you have read and are familiar with Section 1: Safety and the “Operation Musts” in this section.
2.Place the workpiece so the concave side is down on the infeed table and press the workpiece firmly against the fence.
3.Start the jointer.
4.Using push blocks with both hands and keep- ing firm (not hard) pressure on the fence and table, feed the workpiece into the cut- terhead.
5.As your leading hand gets within 4" of the cutterhead, lift the push block up and over the cutterhead and place it on the work- piece as it passes over the outfeed table. Do the same thing when your trailing hand nears the cutterhead and try to maintain pressure on the outfeed table. Never let your hands get closer than 4" from the cut- terhead!
