HAND PLACEMENT
At the start of the cut, the left hand holds the work
firmly against the infeed table and fence while the
right hand pushes the work toward the knives.
After the cut is under way, the new surface rests
firmly on the outfeed table. The left hand should
press down on this part, at the same time
maintaining flat contact with the fence. The right
hand presses the work forward and before the
right hand reaches the cutterhead it is moved to
the work on the outfeed table. Follow the 3 inch
rule. Never pass hands directly over the
cutterhead.
SURFACING
Jointing the face of stock, or surfacing, is shown
in Fig. 27. The use of push blocks or pads will
help ensure against the operator's hands coming
into contact with the cutterhead in the event of a
kickback and as the trailing end of the board
passes over the cutterhead.
Adjust the infeed table for depth of cut. Cuts of
approximately 1/16" at a time are recommended,
as this allows better control over the material
being surfaced. More passes can then be made to
reach the desired depth.
Never surface pieces shorter than 12" or thinner
than 3/8" without the use of a special work holding
fixture.
IMPORTANT: When stock is longer than twice
the length of the infeed and outfeed tables, an
assistant or support table must be used to support
the stock.
WARNING: Always use a hold down or
push block when surfacing short stock
or stock less than 3 inches thick.
JOINTING WARPED SURFACES
If the wood to be jointed is dished or warped, take
light cuts until the surface is flat. Avoid forcing
such material down against the table; excessive
pressure will spring it while passing the knives,
and it will spring back and remain curved after the
cut is completed.
