Edge Jointing
Edge jointing is passing the workpiece over the
jointer on its edge as shown in
Figure 37
. This
process makes the edges of a workpiece per-
fectly flat.
Stock must be edge jointed on the concave side.
The convex side should then be cut straight with
a table saw. This process is commonly used to
prepare the workpiece to be glued-up as part of
a larger assembly or to simply salvage warped
stock.
Figure 38
shows an example of an operator edge
jointing. Notice that the operator’s body is not
directly in line with the stock and that he main-
tains a stable hand position while keeping the
board firmly on the table and against the fence.
To perform an edge jointing operation:
1.
Follow
Section 1: Safety
and the “Operation
Musts” in this section.
2.
Place the workpiece so the concave edge is
down on the infeed table and press the
workpiece firmly against the fence.
3.
Start the jointer.
4.
Using a tight grip with your hands in a sta-
ble position and keeping the workpiece
firmly against the table and fence, feed the
workpiece into the cutterhead.
5.
If your leading hand gets within 4" of the
cutterhead, lift it up and over the cutter-
head and place it on the workpiece as it
passes over the outfeed table. Do the same
thing when your trailing hand nears the cut-
terhead and try to maintain pressure on the
outfeed table. Never let your hands get
closer than 4" from the cutterhead!
6.
Repeat
steps 4-5
until the surface is flat.
