JOINTING AN EDGE
This is the most common operation for the jointer. Set the guide fence square with the table. Depth of cut should be the minimum required to obtain a straight edge. Hold the best face of the piece firmly against the fence throughout the feed as shown in Fig. 37.
DO NOT perform jointing operations on material shorter than 10 inches, narrower than 3/4 inch or less than 1/2 inch thick.
NEVER pass your hands directly over the cutterhead and use push blocks to feed the workpiece whenever possible.
PLANING OR SURFACING
Planing or surfacing is identical to the jointing operation except for the position of the workpiece. For planing, the major flat surface of the workpiece is placed on the infeed table of the jointer with the narrow edge of the workpiece against the fence, as shown in Fig. 38. The workpiece is moved from the infeed table, across the cutterhead to the outfeed table establishing a flat surface on the workpiece. Always use push blocks when performing planing operations and NEVER pass your hands directly over the cutterhead.
DO NOT perform planing or surfacing operations on mater- ial shorter than 10 inches, narrower than 3/4 inch, wider than 12 inches or less than 1/2 inch thick.
BEVELING
To cut a bevel, lock the fence at the required angle and run the work across the knives while keeping the work firmly against the fence and tables. Several passes may be necessary to arrive at the desired result. When the angle is small, there is little difference whether the fence is tilted to the right or left. However, at greater angles approaching 45 degrees, it is increasingly difficult to hold the work properly when the fence is tilted to the right. The advantage of the
When tilted to the left, the fence forms a
