Edge Jointing
1. Set the fence to 90°.
2. Inspect stock for quality issues and grain
orientation. Make sure the stock has a flat
surface to feed against the fence. For
crooked stock, begin edge jointing with the
concaved edge.
3. Set the depth of cut. If an edge is almost flat
and squared, set the depth of cut to only
remove as much material as needed to
obtain a jointed edge. This jointer can
remove at most 1/8" of materials per pass.
Stock that has a rough edge may take
multiple passes to joint it straight and
squared. For some extreme cases, consider
using a saw and a special jig to create a
roughly straight edge before jointing.
4. Start the dust collection system and the
jointer.
5. Place the workpiece on the infeed table,
then use push blocks to hold it against the
fence and the table to initiate a cut.
Be very careful when jointing narrow boards.
Use push blocks to keep hands away from
the cutterhead. Position both hands and the
push blocks above the cutterhead guard
when feeding.
When edge jointing a board that is much
taller than the fence, using the right hand to
hold the board will provide better control.
Continue to use a push block on the left hand
to keep it away from the cutterhead.
Be sure the right hand is securely resting on
top of stock and it is away from the
cutterhead at all times.
6. Feed the entire length of the stock through
the cutterhead. Maintain a stable, balanced
stance for the entire process.
7. For long stock, feed a section past the
cutterhead, then continue to feed the
remaining length while standing next to the
outfeed table.
8. Repeat the process until the entire edge is
jointed flat and square.
TIP: Occasionally adjust fence position to make
use of the outboard edge of the cutterhead. This
helps to average the use of the cutters.
Beveling
Instructions and precautions for edge jointing
apply to beveling. Besides:
•
When cutting a bevel that is not 90°, lift up
the 90° fence stop block, then set the fence
tilt to the desired angle of cut using a
protractor.
•
Reduce the maximum depth of cut from 1/8”
to 1/16” or less based on the width of the
bevel and hardness of the workpiece.
