FENCE SETTING

AND

ALIGNINGI-

On

despatch

from

the

works

the

movements

of

the

fence

have

been

finely

adjusted

for

accurate

cutting

by

the

provi,sion

of

the

setting

screws

at

points

F.G.H. I.

(FIG

C2).

These

adjustments

have

seperate

uses,

and

should

only

be

re-set

to

compensate

for

wear

which

may

take

place

from

constant

use.

The

seperate

uses

of

these

points

are

as

outlined

underneath:-

POINT

F&-

is

an

eccentrically

turned

centre

which

allows

the

fence

to

be

set

paralell

to

the

saw.

or

to

be

set

in

or

out

as

requ

tred.

POINT

G:-

is

s

true

centre

which

allows

slackness

to

be

removed

between

centres

F

and

G.

POINT H:-

is

a

jacking

point

which

provides

a

positive

stop

which

will

not

allow

the

fence

to

be

pulled

up

further

than

90

degrees

to

the

table

when

set

correctly.

POINT

1:-

is

also

a

PACKING.

It

is

usual

to

it

is

not

th"t

this

packing

be

used

as

"

R"uioe

for

buckleo

or

out-of-true

saws.

The

idea

of

fitting

pi-.ckinp,'

piecAs

into

the

table

and

gap

plate

is

to

steady

the

saw,

but

it

should

he

noted

that

the

packing

must

not

be

"s

this

"ill

generate

heat,

resulting

in

a

consequent

loss

of

in

the

blaoe.

The

arrangement

of'

the

packing's

are

in

such

a

way

thRt

"

of'

a

It

shoulrl
