The motor bracket (Fig. 3) is attached to the headstock by means of Allen
setscrews. These setscrews are located at either end of the headstock. Loosen
them with the wrench provided and remove the motor bracket. Never loosen the
set-screws in the motor bracket itself. Attach motor to bracket with four ¼ by 1-inch
machine bolts and washers which are included in the carton, but do not tighten bolts
until motor has been finally positioned. With Shopsmith in vertical position, insert
motor bracket rods into holes on base of headstock and hold motor bracket in place
by tightening the Allen setscrews. Lower the Shopsmith to horizontal position.
ATTACHING MOTOR SWITCH - Loosen the motor bracket set-screws and lower the
bracket and motor to leave an opening of approximately 2" between the bracket and
the headstock. Remove the bottom screw in the nameplate, and pivot the
nameplate around the upper pin. This reveals a hole beneath the nameplate which
facilitates insertion of the switch. Before attaching the switch the necessary
connections should be made.
The Shopsmith motor is equipped with a short lead wire to connect with the switch.
If you do not have a Shopsmith motor, use an 18-inch length of No. 18 rubber-
insulated cord. Thread short wire through the motor bracket slot and connect to the
switch, as shown (Fig. 4). Then insert the terminal end of the long lead cord through the motor bracket slot and make a loop
knot (see Fig. 4) to take up strain which would otherwise be placed on switch connection. Secure all terminals to switch.
Remove both threaded lock-nuts and ON-OFF plate from the shank of the switch. Insert the switch between the motor bracket
and headstock and put your hand through nameplate opening to guide the switch into the hole provided for it in the headstock.
Replace ON-OFF plate and run the lock-nuts down hand-tight temporarily.
Do not tighten the switch in its final position until the OFF position of the toggle lever points toward the tubular ways. Installation
of the switch in this way is a safety precaution and prevents accidental contacts from turning on the power. Replace nameplate
screw and proceed as shown in the following section.
ADJUSTING PULLEYS AND BELTS - Attach motor pulley (small pulley closest to motor) on the motor shaft. With Shopsmith in its
horizontal position - be sure setscrews on motor bracket rods are tight - align motor pulley with headstock pulley by adjusting
motor until the two are in line. Tighten motor to bracket, but do not apply belt to pulley until motor wires have been connected to
lead wire and switch and the motor tested for correct rotation. Motor should run clockwise when viewed from the motor pulley
end (Fig. 2).
With correct rotation of the motor established, apply the V-belt. If the motor used has a larger diameter than the standard
Shopsmith motor, a longer V-belt may be required-due to the difference in the center distance between shaft and motor bracket.
Belt tension can be increased or diminished by adjusting motor bracket rods in the headstock. Belt should be sufficiently tight so
that it will not rub against ways at any pulley speed. Avoid excessive belt tension, which will impose a damaging load on
bearings, shorten belt life and waste power. Also, note that the motor and headstock pulleys should be accurately aligned. This
can be readily accomplished by using a carpenter's square, with one leg lying on the table and the other against the two pulleys.
CAUTION: Should spindle bearings heat up, check belt tension immediately. Remember that the belt should be tightened
sufficiently so that it will not rub against the tubular ways, but not so tight that the belt cannot be deflected approximately one
inch by applying reasonable pressure against it at a point opposite the ways.
STORING ATTACHMENTS - Shopsmith will perform most efficiently if some provision is made at once for properly storing the
interchangeable parts on hooks, shelves, racks or cabinets where they will be convenient to the basic unit. In addition, take the
usual precautions against accidental damage and corrosion.
DESCRIPTION OF MAJOR PARTS
To understand and appreciate what Shopsmith can do, you should be familiar with the principal parts and their uses. Carefully
observe the brief descriptions and illustrations that follow:
FRAME ASSEMBLY-is the basic structure (Fig. 2). It consists of two center-less-ground steel tubes, base plate, base plate arm, tie
bar and headrest. With the exception of the tubes and headrest, all of these parts are high-quality cast iron, precisely bored in
fixtures that assure their permanent alignment.
The headstock and carriage can be removed from the ways by releasing Allen screws on each side of the tie-bar and sliding off
the headstock and carriage. The tubular ways have been factory-aligned but, if they should be loosened, re-align them as
follows:
