Jointing An Edge; Direction Of Grain - Steel City 40540 User Manual

The following directions will give the beginner a start on jointer operations. Use scrap pieces of lumber to check settings
and to get the feel of the operations before attempting regular work.
PLACEMENT OF HANDS
DURING FEEDING
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 underway, the new surface rests firmly on the outfeed
table. The left hand should then be moved to the work
on the outfeed table, at the same time maintaining flat
contact with the fence. The right hand presses the work
forward, and before the right hand reaches the cutter-
head, it should be moved to the work on the outfeed
table.
! WARNING
NEVER PASS HANDS DIRECTLY OVER THE
CUTTERHEAD.

DIRECTION OF GRAIN

Avoid feeding work into the jointer against the grain.
The result will be chipped and splintered edges. Feed
with the grain to obtain a smooth surface.
FENCE OPERATION
The fence can be moved across the table by loosening
the lock knob (A), moving the fence to the desired posi-
tion, and retightening the lock knob securely. As the
fence is moved across the table, the sliding portion of
the fence bracket (B) guards the cutterhead in back of
the fence. SEE FIG 9.

JOINTING AN EDGE

This is the most common operation for the jointer.
These cuts are made to square an edge of a work-
piece. Set the guide fence square with the table. Depth
of cut should be the minimum required to obtain a
straight edge. Hold the best face of the piece firmly
against the fence throughout the feed. SEE FIG.10.
Fig.10
CAUTION
!
MAXIMUM DEPTH OF CUT SHOULD NOT BE MORE
THAN 1/8" IN ONE PASS.
CAUTION
!
DO NOT PERFORM JOINTING OPERATIONS ON
MATERIAL SHORTER THAN 10 INCHES, NARROW-
ER THAN 3/4 INCH, OR LESS THAN 1/2 INCH THICK.
CUTTING A RABBET
When making a rabbet cut, the cutterhead guard must
be removed.
CAUTION
!
AFTER THE RABBET CUT IS COMPLETED, BE
CERTAIN GUARD IS REPLACED.
1. Adjust the fence so that the distance between the
end of the knives and the fence is equal to the
width of the rabbet.
2. Lower the infeed table an amount equal to the
depth of the rabbet. If the rabbet is quite deep, it
may be necessary to cut it in two or more passes.
In that event, the table is lowered an amount equal
to about half the depth of the rabbet for the first
pass, then lowered again to proper depth to com-
plete the cut.
