infeed table and the major flat surface of
the workpiece against the fence (Fig. 28).
Planing cuts are similar. The major surface
of the workpiece is placed on the table with
the narrow edge of the workpiece against
the fence (Fig. 29).
For jointing and planing cuts pressure is
directed three ways; into the fence to
ensure a square cut, forward to advance
the stock, and downward to avoid chatter
and vibration.
For jointing when the material is higher than
the fence, the left hand applies pressure
into the fence and down toward the table
while the right hand pushes forward from
behind. Be sure to keep the right hand high
up on the material. (Fig. 28)
For jointing material that is lower than the
fence, use push sticks to protect the hands.
For planing, use handle pads. (Fig. 29)
Never place the right hand on the
trailing edge of the material. Hand
placement on the trailing edge of the
material may cause the hand to come
into contact with the blade.
Feed work from right to left at a steady,
moderate speed. If you feed the material
too slowly, the wood will burn in places. If
you feed the material too quickly, ridges will
appear in the finished surface.
Jointing Warped Material
If the work to be jointed is cupped or
warped, take light, repetitive cuts until the
surface is flat. Forcing the material flat
against the table will still leave a warped
piece after the cuts have been made.
Never joint any material
shorter than eight inches! The material
may tip into the jointer’s throat and be
kicked back! Avoid jointing thin material
which could become jammed under the
fence or blade guard! Failure to comply
may cause serious injury!
Direction of Grain
Feed the material with the grain to avoid
tearout (Fig. 30). If the direction of the
grain changes somewhere in the board, try
reducing depth of cut and slow the feed
speed down to avoid tearout. If results still
aren’t satisfactory, turn the material around
and try feeding through the other way.
