Each jointer is inspected and tested before shipment.
These machines will give excellent results if properly
used and maintained. The adjustments for various
operations are described below; read and follow the
instructions carefully.
The Homecraft 4" Jointer is an accurate machine,
ideal for the home workshop. Its maximum depth of
cut is
~-inch.
CONSTRUCTION FEATURES
Consult your Delta dealer for the correct motor if the
electric current available is different from that indicated
above.
The cutter head of this jointer runs in sealed ball
bearings which need no lubrication throughout their
life. It carries three high speed steel knives which are
easily adjusted and securely locked in their dove-tail
grooves.
The fence is finish ground to increase accuracy, and
is heavily ribbed for rigidity and to prevent warping.
The fence can be easily locked in any position across
the table, and can be tilted 45° right or left. It is also
.provided with an adjustable stop so the fence can be
returned at right angles to the table.
FroRt and ,rear tables are finish ground after" as-
sembly on the base. This additional operation assures
the true alignment necessary for accurate work and is a
feature usually found only in the larger and more
expensive .machines.
Speed of the cutter head should be about 4000 rpm
for best results. The correct speed is obtained with the
No. 60-013 or 62-413 motor by using the 6Y2-inch motor
pulley No. 5650 in conjunction with the
2~-inch
cutter
head pulley
J
-17-S which is furnished on the jointer.
For any other motor, order a pulley of the correct
bore to fit the shaft, give the speed of the motor, and
sper;[ that you want the right diameter for running a
2~.
ch drive pulley at, 4000 rpm.
The cutter head must rotate forward on top. If
your motor runs in the wrong direction, reverse it
according to the manufacturer's instructions, or in the
case of a double-shaft motor, turn it end for end.
The No. 49-172 V-Belt, offered for use with this jointer,
has an outside circumference of 59% inches. It will
accommodate the usual installa s. Consult your Delta
dealer if you need a belt of other length to fit special
conditions.
MOUNTING AND ASSEMBLING
The jointer, shown in Fig. 1, is shipped complete in a
single package marked No. 37-110. It consists of two
units, the body and the fence. The knife guard and a
wrench for the lock screws of the cutter head are included.
The motor and other items of your order are supplied in
separate packages.
In choosing a location for the machine, be sure to
allow clearance in front of and behind the tables for
jointing long pieces.
A portable unit can be made by mounting the jointer
and motor on a 2 x 12-inch dressed pJank 30 inches long.
It may be placed on any convenient work table for opera-
tion and stored on a shelf when not in use. 2-inch blocks
must be inserted under the jointer base for such mount-
ing, to raise the machine so that the motor can be placed
directly back of the rear table and to allow removal of
chips. Use long bolts through the base, blocks and plank.
