JOINTING AN EDGE

This is the most common operation for the jointer, these

cuts are made to square an edge of a workpiece. 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. 44.

MAXIMUM DEPTH OF CUT SHOULD

NOT BE MORE THAN 1/8" IN ONE PASS.

DO NOT PERFORM JOINTING

OPERATIONS ON MATERIAL SHORTER THAN 10

INCHES, NARROWER THAN 3/4 INCH, OR LESS

THAN 1/2 INCH THICK (REFER TO FIG. 45).

SURFACING

Surfacing is identical to the jointing operation except for

the position of the workpiece. For surfacing, 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, a shown in Fig. 46. 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 SURFACING OPERATIONS AND NEVER

PASS YOUR HANDS DIRECTLY OVER THE

CUTTERHEAD.

MAXIMUM DEPTH OF CUT SHOULD

NOT BE MORE THAN 1/8" IN ONE PASS.

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 double-tilting fence is

appreciated under such conditions. When tilted to the

left, the fence forms a V-shape with the tables, as shown

in Fig. 47, and the work is easily pressed into the pocket

while passing it across the knives. If the bevel is laid out

on the piece in such direction that this involves cutting

against the grain, it will be better to tilt the fence to the

right.
