Spinner

 

Components

 

The

 

spinner

 

is

 

composed

 

of

 

fiberglassed

 

blue

 

foam.

 

The

 

spinner

 

is

 

made

 

from

 

blue

 

foam

 

which

 

is

 

tack

 

glued

 

to

 

a

 

piece

 

of

 

1/32”

 

ply.

 

Epoxy

 

a

 

short

 

1/4”

 

diameter

 

dowel

 

to

 

the

 

back

 

in

 

the

 

center

 

of

 

the

 

disk.

  

 

Place

 

the

 

assembly

 

in

 

a

 

drill

 

chuck

 

and

 

sand

 

the

 

foam

 

to

 

shape

 

while

 

it

 

spins.

 

Glass

 

the

 

foam

 

using

 

standard

 

glassing

 

techniques.

  

 

When

 

the

 

epoxy

 

is

 

ready,

 

cut

 

the

 

excess

 

fiberglass

 

away.

 

Then

 

remove

 

the

 

plywood

 

and

 

carve

 

out

 

the

 

necessary

 

recess

 

for

 

the

 

propeller.

 

Drill

 

out

 

the

 

dowel

 

on

 

the

 

plywood

 

disk.

 

Glue

 

the

 

spinner

 

to

 

the

 

plywood

 

disk

 

after

 

the

 

prop

 

is

 

mounted

 

to

 

the

 

model.

 

It

 

should

 

be

 

perfectly

 

aligned

 

with

 

the

 

fuselage.

  

It

 

looks

 

complicated

 

but

 

in

 

practice

 

the

 

process

 

goes

 

easily

 

and

 

works

 

very

 

well.

  

 

Spinner

 

 

COVERING

 

Any

 

lightweight

 

covering

 

material

 

can

 

be

 

used.

 

Polyspan

 

with

 

dope

 

or

 

Minwax

 

Polycrylic

 

makes

 

a

 

good

 

choice.

  

Litespan

 

is

 

also

 

popular.

  

Dave

 

Ottney

 

used

 

Litespan.

  

He

 

also

 

used

 

water

soluble

 

polyurethane

 

to

 

seal

 

and

 

stain

 

to

 

finish

 

his

 

fuselage.

   

Decal

 

outlines

 

for

 

this

 

model

 

are

 

available

 

on

paper

 

used

 

for

 

kitchen

 

shelf

 

lining

 

makes

 

excellent

 

decals.

 

Print

 

out

 

the

 

decal

 

on

 

paper,

 

glue

 

with

 

a

 

glue

 

stick

 

to

 

the

 

paper

 

backing

 

on

 

the

 

shelf

 

paper,

 

cut

 

the

 

decal

 

out

 

with

 

an

 

Exacto

 

knife

 

or

 

micro

 

scissors.

  

Peel

 

off

 

the

 

paper

 

and

 

adhere

 

to

 

your

 

model.

 

Use

 

black

 

material

 

for

 

the

 

crosses

 

and

 

white

 

for

 

the

 

backgrounds.

  

WHEELS

 

Gluing

 

the

 

ply

 

sides

 

on

 

the

 

balsa

 

core

 

makes

 

the

 

basis

 

for

 

the

 

wheels.

 

Use

 

the

 

brass

 

hub

 

for

 

alignment.

 

Epoxy

 

the

 

hubs

 

in

 

place

 

and

 

add

 

a

 

sufficient

 

amount

 

of

 

epoxy

 

around

 

the

 

base

 

of

 

the

 

hub

 

to

 

reinforce

 

the

 

connection

 

of

 

the

 

hub

 

to

 

the

 

ply.

 

Plywood

 

reinforcing

 

hubs

 

are

 

provided

 

that

 

are

 

to

 

slip

 

over

 

the

 

brass

 

tubing

 

as

 

shown.

   

Next,

 

CA

 

glue

 

the

 

neoprene

 

cording

 

together

 

to

 

from

 

a

 

“tire”.

 

Use

 

thin

 

CA

 

sparingly

 

as

 

the

 

CA

 

bonds

 

very

 

aggressively

 

to

 

the

 

rubber.

 

Press

 

the

 

CA

 

wetted

 

ends

 

together

 

for

 

an

 

instant

 

bond.

 

The

 

best

 

way

 

to

 

align

 

the

 

ends

 

is

 

to

 

glue

 

them

 

while

 

they

 

are

 

in

 

place

 

on

 

the

 

wheel.

 

Then

 

attach

 

the

 

tires

 

to

 

the

 

wheels

 

and

 

CA

 

in

 

place.

 

A

 

thin

 

bead

 

of

 

CA

 

around

 

the

 

rim

 

makes

 

for

 

a

 

secure

 

tire.

  

Paper

 

cones

 

are

 

cut

 

out.

  

Use

 

a

 

ball

 

point

 

pen

 

to

 

score

 

each

 

line

 

on

 

the

 

back

 

to

 

make

 

an

 

impression

 

of

 

“spokes”

 

It

 

is

 

helpful

 

to

 

do

 

this

 

operation

 

on

 

a

 

paper

 

tablet

 

so

 

that

 

the

 

pen

 

makes

 

a

 

good

 

crease.

 

Fold

 

the

 

paper

 

along

 

the

 

crease

 

lines

 

to

 

exaggerate

 

the

 

raised

 

lines.

 

One

 

of

 

the

 

sections

 

forming

 

a

 

wedge

 

is

 

cut

 

out.

  

Make

 

cuts

 

to

 

the

 

center

 

of

 

the

 

circle

 

along

 

a

 

pair

 

of

 

the

 

spokes.

  

Close

 

the

 

paper

 

cut

out

 

to

 

form

 

a

 

cone

 

and

 

tape

 

the

 

joint

 

inside

 

the

 

cone.

  

The

 

inside

 

cones

 

may

 

now

 

be

 

attached

 

to

 

the

 

wheels.

 

The

 

outside

 

cones

 

may

 

be

 

attached

 

at

 

his

 

point

 

if

 

wheel

 

collars

 

are

 

to

 

be

 

used.

 

Alternatively,

 

after

 

installing

 

the

 

wheels

 

on

 

the

 

landing

 

gear,

 

a

 

washer

 

may

 

be

 

soldered

 

to

 

hold

 

the

 

wheel

 

in

 

place

 

and

 

then

 

the

 

cone

 

is

 

attached.

 

This

 

method

 

makes

 

a

 

very

 

nice

 

scale

 

appearance.
