The

Chest

6.

One

problem,

which

may

happen

to

the

Hand

Slide

movement,

is

that

the

guide

shaft

(A) may

become

misaligned

and

may

not

operate

smoothly.

Their

are

two

causes

of

shaft

misalignment:

one,

is

that

the

wooden

mounts

in

the

fiberglass

guitar

warp

and

will

eventually

bend

the

aluminum

neck of

the

guitar.

Two,

the

rear

end of

the

cylinder

will

catch

on

the

fur

when

the

Guitar

Rock

movement

is

in

operation.

This

is

usually

caused

by

the

critical

adjustments

being

off

or

the

fiberglass

body

being

mounted

too

far

forward.

To

discover

if

the

problem

is

with

the

fiberglass

body

being

to

far

forward,

manually

operate

the

Guitar

Rock

movement

and

see

if

the

cylinder

is

touching

the

body.

If

it

is

to

far

forward,

refer

to

Pages

3-136

thru

3-187

Cosmetics,

and

mount

the

body

correctly.

Next

move

guide

shaft

(A) .

If

the

shaft

does

not

move

smoothly

and

easily,

due

to

either

reason

described

above,

it

needs

to

be

repaired.

a.

Label

the

air

lines

to

the

hand

slide

cylinder

and

pull

them.

b.

Detach

the

the

guitar

from

the

mount

plate

(B).

Save

the

bolts,

note

the

mount

holes

and

bring

the

guitar

to

the

Technical

Room.

c.

Remove

the

fiberglass

guitar

from

the

mechanism

and

place

it

to

the

side,

put

it

where

it

won't

get

scratched.

d.

Try

the

mechanism

again,

if

it

works

properly,

the

problem·is

that

the

wood

mount

pieces

in

the

fiberglass

guitar

have

warped.

Plane

the

wood

pieces

or

shim

the

mounting

screws.

After

it

works

re-assemble

the

guitar

back

on

to

the

character.

e.

Did

the

mechanism

not

work

properly

when

you

tried

it

again?

If

not,

place

an

Adjustable

Wrench

at

the

end

of

the

aluminum

guitar

neck

and

twist

it

one

way

or

the

other

to

try

to

straighten

the

neck

and

get

the

movement

working

properly.

If

this

works,

the

wood

mount

pieces

in

the

fiberglass

guitar

have

warped

and

bent

the

neck,

plane

them

or

shim

the

mounting

screws

when

re-attaching

the

fiberglass

guitar.

f.

If

the

rear

end

of

the

cylinder

caught

on

the

fur,

the

front

cylinder

mount

piece

(C)

has

bent.

Place

an

Adjustable

Wrench

on

it

and

try

to

bend

it

back

so

the

movement

functions.

g.

If

the

Guide

shaft

has

misaligned,

rebuilding

of

the

cylinder

is

required.

(See

Pages

3-009

thru

3-011,

and

all

drawings

referred

to

by

that

text)

h.

After

the

mechanism

works

properly,

re-attach

the

guitar

to

the

character,

and

set

all

critical

adjustments.
