FITTING

BANDSAW

BLADES

SAW

GUIDES -

Fig.

7.

When

placing

a

saw

on

the

machine

the

top

and

bottom

guides

must

be

moved

well

back

and

the

saw

tracked

or

adjusted

to

run

in

the

centre

of

the

saw

wheels.

Afterwards

bring

both

guides

forward

until

the

discs

barely

touch

the

saw

when

not

working

..

The'side

blocks

on

the

guides

should

support

the

saw

on

the

sides,

but

not

allowed

to nip

the

blade.

Keep the

side

blocks

up' to the

gullets

(if

the

teeth

only

leaving

the

teeth

clear.

When

using

saws

of

the

same

width

they

will

usually

run

successfully

without

altering

the

adjustment,

but

when

wider

ones

are

used

the

guides

must

be

moved

back

and

the

saw

re-tracked.

To

obtain

first

class

sawing,

the

guides

must

be

dead

in

line

and

fixed

immediately

above

the

work.

TENSIONING -

Fig.

8.

Incorrect

tension

or

tightness

of

the

blade

over

the

saw

will

end

in

saw

breakage.

The

scale

and

pointer

are

set

before

despatch,

but

should

they

be

displaced

in

transit

it

is

necessary

to

re-set

them

before

use.

In

placing

a

saw

on

the

pulleys

it

should

be

sufficiently

tight

until

it

can

be

pulled

out

ttl

from

its

true

line

at

a

central

point,

between

the two

pulleys.

When

this

is

done,

move

the

pointer

until

the

scale

coincides

with

the

width

of

the

saw.

For

a

~"

blade. the

pointer

should

read

~".

If

the

machine

is

left

standing

for

a

period,

e.

g.

overnight,

the

tension

should

be

reduced,

and

the

blade

re-

tensioned

before

putting

the

machine

into

operation

again.

IMPORTANT.

After

the

pointer

is

fixed

in

this

manner

it

will

read

correctly

for

any

width of

blade

without

further

alteration,

even

if

the

length

of

saw

varies

for

any

given

width.

For

a

i"blade

the

pOinter

should

read

i",

etc.

TRACKING -Fig. 9.

Every

saw

has

slightly

different

running

characteristics

on a

band

saw

machine

due to the condition of the

steel

ribbon

it

is

made

from,

the

brazed

joint

and

the

tension

in the

blade

ribbon.

This

is

compensated

by

using

a

crowned

(O,r

slightly

curved)

rubber

on the

wheels

and

prov-

•

iding the top wheel with a

slight

tilting movement.

We

call

this

track-

\

ing

and

by

slackening

the

lock

handle

and

adjusting

the

tracking

hand-

wheel,

it

is

possible

to

adjust

the

tilt

of the top wheel,

so

that the

saw

runs

steadily

in the

centre

of the wheel.

This

is

important

because

the

blade

then

passes

in a

straight

line

between the top and bottom

wheel, and does not snake. When the

latter

occurs

the

back

of the

saw,

keeps

hitting the guide

plate

and

woodwork and damaged guides

result.

Do

not

forget

to

re-tighten

the

tracking

lock

bolt

after

adjusting.

SAW

PULLEYS

A

brush

as

shown

in

Fig. 10

is

provided

on the

bottom

pulley to

remove

sawdust,

whilst

the

rubber

on the top

pulley

should be cleaneq daily to

prevent

accumulation

of

sawdust

which would

cause

the

blades

to

run

out

of

true

line.

.

The

saw

pulleys

must

be

kept

in

accurate

balance

to avoid

vibration.

It

is

essential

that

the

rubbers

on the

faces

of the

pulleys

are

kept

at

an

even

thickness

by

truing

up

occasionally

or

if

they

are

badly

worn

should

be

replaced

by new

ones.

If

the

machine

is

used

with badly

worn

pulleys

the

saw

will

vibrate,

resulting

in

bad

sawing and

broken

saws.

We

have a

service

arrangement

which we

recommend

whereby newly

rubbered

pulleys

can

be

supplied

against

the

return

of the

existing

pulleys,

an

appropriate

charge

being

made

to

cover

re-rubbering

only.

Where

it

is

not pra.ctical

for

the

customer

to

use

our

exchange

service

of

vulcanised

wheels

it

is

possible

for

the

customer

to

carry

out

his

ownre-rubbering,

which,

whilst

not

so

good

as

the

vulcanised

process,

is

satisfactory

if

the

instructions

below

are

carefully

followed. Rubber

bands

and

solution

can

be

supplied to

REMOVAL

OF

SAW

PULLEYS.

The top

bottom

pulleys

are

idelltical,

and

when taking

them

from

the

machine

for

re-rubber-

ing the

entire

wheel

comprising

plate

and

hub

should

be

removed.

To do

this

remove

the

spindle

nut

and

withdraw the

wheel

complete.

It

should

be

noted

that

for

both

pulleys

this

locknut

has

a

FIXING INSTRUCTIONS FOR THE APPLICATION OF RUBBER

BANDS

TO

BAND

SAW

PULLEYS.

The

Croid

Glue

No.9

supplied

is

ready

for

use

and

should

be

applied

cold.

In cold

weather

and

if

the glue

is

solidified

warm

up to 800

Fahrenheit

to give fluidity

and

to

assist

spreading.

Thoroughly

scrape

and

clean

the

face

of the wheel

free

from

old

abrasive.

This

is

very

import-

ant.

Stretch

the

rubber

band

over

the wheel.

To

assist

with the

application

of the glue

it

will

be

found

more

convenient to

place

between

the

wheel

rim

and

the

rubber

a

piece

of wood

approximately

lin

diameter.

Apply the glue

across

the

face

of the

wheel

and

turn

the wood

round

the

rim

thereby

exposing a

section

of the

rim

to

be

glued.

Proceed

until

the whole of the wheel

has

been

covered

taking

care

to

glu"e

the whole

face

in

order

to

obtain

adhesion

over

the whole width to

prevent

the

edges

of

the

band

lifting.

Tightly

apply a

piece

of

tape

of the

same

width

as

the

wheel

around

the

circumference,

thereby

giving

as

much

pressure

as

possible

to the

rubber

band.

Leave

at

least

24

hours

before

use.

Finally

true

up the

rubber

and

put

a

slight

crown

on the

face.

This

is

done

by

revolving

the

wheel

and

holding

against

it

a wood

block

covered

with

emery

cloth,

preferably

when mounted

on the

machine.

Check wheel

for

balance

before

use.

FOR TROPICAL COUNTRIES a

Croid

Glue No. 10

is

supplied

with a

hardening

powder

which

must

be

added

in

the

proportion

of one

part

of

hardener

to

56

parts

by

weight

of

glue

and

thoroughly mixed. The

remainder

of

the

procedure

for

cleaning

and

fixing

is

the

same

as

in

the

instructions

above.

BRAZER.

TYPE

H.E.

This

machine

is

suitable

for

brazing

band-

saws

from

i"

to

1"

wide,

and

is

very

useful

for

the

efficient

brazing

of

blades

which have

become

broken.

The two

ends

of the

saw

are

firmly

held

by

the

clamps,

and

controlled

heat

applied

electrically.

A

small

quantity

of

solder

and

brazing

compound

are

supplied

with

the

machine.

The

actual

brazing

takes

from

25

to 45

seconds

according

to

width

of

blade.

Before

brazing

the ends of

the

saw

blade

must

be

carefully

bevelled.

A

separ-

ate

instruction

chart

is

issued

with

the

brazer.
