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.
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 simply spring back and
remain curved after the cut is completed.
Edge Jointing
This is the most common operation for the
jointer. Set guide fence square with the table.
Depth of cut should be the minimum required to
obtain a straight edge. Do not make cuts deeper
than 1/8" in a single pass. Hold the best face of
the piece firmly against the fence throughout the
feed. See Figure 35.
When edging stock wider than 3 inches, lap the
fingers over the top of the wood, extending them
back over the fence so that the fence casting will
act as a stop for the hands in the event of a
kickback.
Beveling
Never make cuts deeper than 1/16 inch when
beveling. Make certain material being beveled is
over 12 inches long, more than 1/4" thick and 1"
wide.
Although the fence may be
tilted in or out for a bevel cut, It is
recommended for safety reasons that the
fence be tilted in toward the operator,
making a cradled cut.
Set fence to desired angle. For stock wider than
3", hold with the fingers close together near the
top of the stock, lapping over the board and
extending over the fence. When beveling
material less than 3" wide, use beveled push
blocks.
