Fortunately,

we

found

there

would

be plenty of room to mount

the chassis

in

the

telephone

compartment

and also to

fasten it

to the dial.

Masking

tape

was

placed

on

the marked

edge

of the antique cabinet

to serve as a

guide line

for the

dial cutout and to protect

the case against

possible

and scratches.

Wood screws and

spacers

were

used to fasten the chassis

to the

tele-

phone base.

With the plastic dial in the new opening.

we

drilled

two mounting holes at either

end

so

the

dial could

be

fastened

to the

tele-

phone cabinet. The dial

was

mounted

in

was then bolted

to the dial

itself.

Finishing

Touches.

With

the

project

al-

most completed,

we

then soldered

the

wires

from the

output

transformer to the

speaker

voice -coil terminals

and

taped the FM an-

tenna

wire

to the

inside

of

the telephone

cabinet.

After the radio

had been mounted

and tested,

we

sealed the

dial in place by

squirting rubber

seal around

the dial.

Later, we removed the

telephone bells,

front

mouthpiece, and hand

phone hanger

from the cabinet and

spray -painted them

with black

enamel.

When they were dry, we

remounted

them in position, then touched

up the

telephone cabinet proper

with

two

coats of

varnish.

And last

of all,

we
