FICURE

I

You now

have

a versatile

tool incorporating the mul-

tiple

advantages

of

belt,

drum, disc and fexible belt

sanding.

The

design features

the variable

position-

itg of

work surfaces,

both for

ease

of operation and

for

the sanding

of

nearly all

types

of

cuts.

Rigid

cast iron

construction

provides

the

necess

ary

stability

to

produce

accurate

and

precise

sanding

op-

erations.

To

prevent

damage in

shipment

some of the

parts

were

disassembled

from

the

tool. These

parts

are

listed

below.

Be sure they

are all

accounted for be-

fore

discarding

any

of the

packing

materials.

ASSEMBLY

Place the

disc assembly

on the end

of the

shaft,

No.

9

,

being

sure

that the

set

scr€w, No.

43, contacts

the

fat

on

the

shaft.

Tighten

the set

screw

securely.

The

work

table

may

now

be assembled

to the

tool

in

position

for

use with

either

the

sanding

disc

,rr

the

sanding belt, by

placing

the support rod,

No. 52,

into

one

of the holes

provided

in

the

base,

No.

34, and

locking with

either hex head

screw, No. 35,

or

No.

37,

which

are already

assembled

into the base.

It

is

suggested,

however,

that the

work table first

be

in-

stalled for

use with

the

sanding

disc

until

the

work

table

stop screws

are

adjusted, as explained

under

ADJUSTMENTS.

INSTALLATION

There are two

V's

diameter

holes in the base

of the

sander through which

bolts may

be inserted

to mount

the tool

securely to

a

well

constructed

bench

or tool

stand.

The

bench

should be constructed

to

bring

the

top

surface

of the

belt

table

to approximately

36

inches

from

the

floor.

The

motor should

be mounted

below

the tool to

allow

complete

freedom

of operation.

MOTOR

A

Yz

horsepower, 3450

R.P.M. motor

will

provide

adequate

power

f

or

general

use. For

continuous

heavy

duty operation

a

%

horsepower, 3450

R.P.M.

motor is recommended.

Rotation

must

be

counter-clockwise when

facing

the

sanding disc.

SPEED

For best

perf

ormance

this tool

should

run at

8p-

proximately

2700

R.P.M. This

speed

is

attained

by

using

a 2 inch

diameter

motor

pulley

with a

Yz

inch

V-groove.

Be

sure

to

specify

the

shaft

diameter

of

your

motor

when

ordering

the

motor

pulley.

BETT

Use a

standard

%

inch V-belt.

To

determine the

belt

length

place

rhotor

and

tool

in operati.g

posi-

tion

and measure

around

the outside

of

the

pulleys

with

a steel tape.

Do

not measure

in

the

grooves.

TUBRICATION

This

sander

is equipped

with

precision

type, sealed

ball

bearings.

These

bearings

were

packed

with

grease

at

the factory

and

require

no additional

lubri-

cation

for

the

life

of

the bearing.

To

maintain

smooth

and

easy

operation

of the

controls,

oil

the

following

parts

occasionally

with any

good

grade

lock knob

locks

the

work

table

at any

desired degree

of tilt from 0o

pulleys

and remain

in

one

position

on

the

pulleys,

as

For

extreme

accuracy

the

pro-

should

be

set

in

relation

to

the

sand-

or belt

table

each

time

a

is

desired.

OPERATION

The sanding

belt

and

sanding

disc

furnished

with

this

tool are

for

general

use.

They

are

suitable

for

use

on

materials

such

as

metal,

wood,

or

plastics.

Since

a non-hardening

type

of

disc cement-[.as

been

used

to fasten

the

abrasive

paper

to

the spnding

plate,

the

abrasive

disc may

be

quickly

replaced

with

one of

a different

grit.

Drum

sanding

may

be

done

at either

end of

the

sanding

belt

table.

See

Fig.

4 for

a typical

applica-

tion.

Flexible

belt sanding

may

be

done

on the

back

of

the

belt

with

the

belt

table

in

vertical

position,

&s

shown

in

Fig.

5.

Release

the

belt

tension

to

suit the

curve

of

the

work

piece.

Quality

of finish

d.pends

entirely

upon the

abra-

sive

grit

and

the

handling

of the

work.

Highest

qual-

ity

is

obtained

by

first

rough

sanding

with

the coarser

gri_ts,

then

changing

to

finer

grits

and

making

several

light

passes.

Abrasives

are

available

in

three

grits-fine,

rrr€-

dium

and

coarse.

The

belt

and

disc furnished

are

both

medium

grit.

FIGURE

SAFETY

Due

to

the functions

of

this

the

revolving

parts

must

remain

exposed.

Be

careful

firmly

so

that

it

may

not

be

driven

from

your

hands

allowing

them

to

come

in

contact

with

the

abrasive

surfaces.

Use

the

belt

fence

whenever

possible.

Be

sure

the

rotation

is

correct.

Do not

wear

are

loose

or

dangling.

Be
