HOW TO OPERATE AND MAINTAIN
Magna 4” Jointer--Model 4E

toward proficient woodworking. Like SHOPSMITH, the
Jointer is designed to accomplish quickly and accurately
many operations requiring tedious hours of labor if done
by hand. Basically, it is a rotary cutter which will plane
edges smooth and square, ready for gluing or assembling.
It will also do a fine job on light surfacing cuts but should
not be confused with the Thickness Planer as Jointers often
are. The latter is a very heavy industrial machine designed
to dress stock to exact thicknesses.
The basic usefulness of the Jointer is illustrated by a
quick preview of standard operational procedure on a
saw-jointer combination such as you have available with
SH6PSMITH.

HOW TO ADJUST THE JOINTER
The Jointer has been factory adjusted and tested for accuracy. It will operate to high standards if used and maintained correctly. Correct procedures for adjustment and periodical checking are described in the following paragraphs. READ THE INSTRUCTIONS CAREFULLY. The MAGNA 4” JOINTER

Adjusting the guard
The cap on the guard of the MAGNA 4” JOINTER
contains a spring which supplies the pressure that automatically keeps the guard over the cutter head. During
the pass, the guard covers the unused section of the
cutter head while the work itself covers that area which
is cutting. The side pressure of the guard also helps to
keep the work against the fence. NEVER WORK WITH-

In normal operating position the fence should be
perpendicular to the horizontal plane of the tables. To
check, follow this procedure. Use the two-socket wrench
to loosen the nut which secures fence tilt. Set the fence
on the quadrant “zero”

OPERAT ION
The Jointer is used to plane edges square and smooth
and to accomplish other cuts such as those shown in
Fig. IO. Jointing-planing the edge of a board-should
always be done with the grain of the wood. Working
against the grain seldom produces a satisfactory surface
and also increases the danger of kickback (Fig.

As the work advances over the cutter head the guard

either hand over the cutter head but if the work is wide

CARE OF JOINTER KNIVES
With proper care and occasional honing the Jointer knives will function for a long time without regrinding. Occasionally the
knives should be cleansed of the gum and pitch which will adhere to them. If this accumulates it will reduce the efficiency of the knives.
A good way to clean them is to spray them with SHOPSMITH RUST PREVENTIVE (accessory no.
minutes and then wipe off with a rag.
To hone them, wrap an
covered end of the stone on the table so that the exposed end juts out over the cutter head (Fig. 24). The cutter head should be
turned to allow the stone to rest flat on the bevel of the knife. Hold the cutter head in this position (by gripping the drive belt) and
move the stone back and forth across the knife. Hone an equal amount on each knife.
When knives are chipped or otherwise dulled beyond resharpening by honing they must be removed from the cutter head and
refinished on a grinding wheel. Through the use of special homemade jigs this can be accomplished on the table saw (Fig.
