What is Plastic Scale Modeling?
It’s a creative hobby that’s fun, relaxing, and a break from
your everyday responsibilities. It is also a great learning
experience and something you can do with other members of your
family. Scale modeling involves building replicas of any kind
of subject. This can be done as a quickly as an afternoon
project, or you can take many hours to complete your model to
look like a miniature replica of your subject.
History of Plastic Model Production
It all began in England during the mid 1930’s with FROG, and
Penguin producing the first plastic model kits. Kits produced
by Airfix soon followed these. Nearly all of these model kits
depicted English aircraft. Immediately following the end of WW
II American kit manufactures such as Hawk, Monogram, Lindberg,
Revell, and Aurora started to produce kits for a growing
market in America. Today, kit collectors prize many of these
early kits.
The hobby rapidly expanded in the 1960’s and 1970’s, and in
the 1980’s Japanese companies such as Tamiya, Hasegawa,
Fujimi, Otaki, introduced reasonably priced and high quality
kits. The 1990’s introduced still more manufacturers, many
from Eastern Europe, with increasingly greater quality and
specialty items. Today there are kit manufactures from Russia,
Ukraine, Korea, and China producing an ever-greater variety of
kits and specialty items.
The hobby is now a worldwide business. The kit itself has also
evolved from colored and clear plastic parts and standard
decals. Today many model kits may include photo etched and
white metal parts, resin parts, and multiple specialty decals.
An incredible amount of "after market" reference
documentation, additional photo etch, resin conversion parts,
and decals are now available to help you complete the most
accurate representation of your chosen subject. The "after
market" is a huge worldwide industry and one can easily spend
more on these parts than the cost of the model kit itself!
Sadly few American manufacturers remain in business as the
overseas manufacturers have come to dominate the plastic model
industry in recent years.
The Various Scales And Their Principal Uses
Scale represents the size of your model in relationship to the
size of the actual subject. For example 1/72 scale means the
model is 72 times smaller than the actual subject. Remember
the larger the scale numbers the smaller the actual model.
When starting the hobby of plastic model building, it is
important to determine what scale is best suited for you.
There are a number of factors to consider. Most important is
the size of your size work, display, and storage areas. That
is why 1/72 is generally the scale of choice in Europe and
Asia and 1/48 and 1/32 are more popular in the USA. We simply
have more living and recreation space to devote to our hobby.
Some of the more popular scales in use today are 1/72, 1/48,
1/32, 1/24, 1/35, 1/350, and 1/700. The chart below
illustrates some of these scales converted into measurements
in feet. It doesn't include all of the scales that are
available. The type of model kits that commonly use a
particular scale are also shown (in bold print) to assist you
in choosing a model kit to meet your area of interest. (Refer
to a finished model display of the various scales, provided by
your Chapter members).
The Scales
Aircraft Scales 1/24, 1/32, 1/48, 1/72, 1/144, 1/200, 1/350
Military Vehicle Scales 1/16, 1/25, 1/35, 1/48, 1/72, 1/76
Ship Scales 1/96, 1/192, 1/350, 1/500, 1/600, 1/700, 1/720
Auto Scales 1/6, 1/12, 1/20, 1/24, 1/43
1/700 = 1 inch equals 70 feet
1/350 = 1 inch equals 35 feet
1/200 = 1 inch equals 22 feet
1/144 = 1 inch equals 12 feet
1/72 = 1 inch equals 6 feet
1/48 = 1 inch equals 4 feet
1/43 = 1 inch equals 4.3 feet
1/35 = 1 inch equals 3.5 feet
1/32 = 1 inch equals 3.2 feet
1/24 = 1 inch equals 2 feet
Reference and Research Material
An important resource to the modeler is reference materials.
These reference materials can help you in any number of ways.
They can help you build a particular pilot’s plane, or one
that was flown during a certain time period, just to name a
few. These references are not limited to airplanes; they can
help with any subject you choose. Fine Scale Modeler Magazine
is one of the best overall sources for articles on new kit and
product reviews and modeling techniques. Other sources of
reference materials include the Internet, books, IPMS/USA
special interest groups, and let’s not forget your local
Chapter. Many of its members have a vast wealth of knowledge
about many subjects and are willing to help you research your
project.
This Applies To Any Kit You Choose
1. It is now time to decide what scale and subject you want to
start with. Include any "after market" enhancements such as
photo etch parts, special decals, and paint schemes. Decide if
you will display the model with the canopy open or closed,
equipment hatches open or closed, engine and gun bays exposed,
etc. For our class we will use a 1/48 scale Tamiya A6M2 Zero
with an open or closed cockpit.
2. We will build this model kit Out of the Box (OOB) using
only the parts, decals, and reference material provided with
the kit.
NOTE: In the future, you may decide that you want to take your
model kits
to the next level by adding “aftermarket” goodies.
3. As you view the instructions study the assembly steps and
understand how you should begin to assemble this kit.
4. As you visualize the assembly plans and read the
instruction booklet for
this model decide what you should paint as sub-assemblies.
Getting started with the Tamiya 1/48 scale A6M2 Zero
We had to deviate from the Tamiya instructions to accommodate
the time constraints of the class. The constraints are
primarily drying time associated with gluing, seam filling,
and painting.
1. Open the model kit and layout the parts trees and assembly
instructions. Inspect for broken or damaged parts including
decals for scratches. Store the clear plastic parts and decals
in their own clear plastic protective bags to avoid future
scratches.
2. Wash the parts trees in a light solution of dishwashing
liquid and warm water to remove hand and mold release oils.
Carefully dry and set aside.
3. Identify all of the parts that require green chromate on
the entire model while the parts are still attached to the
tree. This includes P/N’s A5 & A6 (Cowl), A8 (Seat), A9
(Cockpit side wall), A11 (Cockpit floor), A12 (Instrument
panel), A13 (Cockpit rear panel), A15 (Control stick), (B26 &
B27 (Fuselage halves), B28 (2 Lower wing wheel wells), B32 (2
Small landing gear doors), B 40 & B41 (Medium landing gear
doors), B47 & B48 (Large landing gear doors). Using the
airbrush, paint all of the parts listed above.
4. Remove the fuselage halves from the parts tree and clean
the mating surfaces of any flashing or other imperfections
that will interfere with the mating surfaces. Dry fit the
mating surfaces to correct any surface imperfections. (Use the
sanding sticks). Tape the fuselage halves together using a low
tack masking tape to prevent them from shifting during the
gluing and drying process, set aside to thoroughly dry.
ASSEMBLY TIP: When using liquid cement you may want to use a
#0 brush to apply the liquid cement. Be careful do not
overload the brush with glue as a small amount is all that’s
need. When the brush touches the seam notice the capillary
action of the glue as it runs along the length of the seam.
Clean all mating parts of paint. Paint will interfere with the
bonding process resulting in a weak joint. Touch up painting
may be necessary.
5. Remove P/N’s A1 & A2 (Top wing halves), and B28 (Lower
wing) from the parts tree. If you are going to install the
drop tank you must drill out the hole in B28 (Lower wing). Dry
fit the mating surfaces and correct any surface imperfections.
Tape, glue and dry as above.
6. Remove the cockpit assembly P/N’s A8 (Seat), A9 (Cockpit
side panel), A11 (Cockpit floor), A12 (Instrument panel), A13
(Cockpit rear panel), Do not remove P/N A15 (Control stick) at
this time. Proceed with the cockpit assembly by first cleaning
and dry fitting the parts for proper fit and alignment. Always
check the assembly plans on any model you make to ensure
correct assembly. Dry fit P/N’s A12 (Instrument panel), A13
(Cockpit rear panel), and A11 (Cockpit floor), into the
fuselage and check the alignment.
ASSEMBLY TIP: To install A11 (Cockpit floor), A13 (Cockpit
rear panel), and A12 (Instrument panel) for tack gluing,
invert the fuselage and install P/N A13 (Cockpit rear panel)
and A12 (Instrument panel) making sure they are seated
correctly, than install A11 (Cockpit floor). Place your finger
on A11 (Cockpit Floor) and turn over the model and check the
fit again, if everything is aligned, tack glue the cockpit
assembly only, do not glue to the fuselage yet.
7. After tack glue has set remove the cockpit assembly from
the fuselage and complete the final gluing of this
sub-assembly and set aside to thoroughly dry.
8. Install the cockpit instrument panel decal using the decal
setting solutions and set aside to dry.
9. Dry fit and install P/N A9 (Cockpit side panel) making sure
that the outside contour is flush with A12 (Instrument panel)
and A13 (Cockpit rear panel) to complete this sub-assembly
after the glue has dried give one final check for alignment.
10. Inspect seams of fuselage and wings for any imperfections
and clean the seams with your sanding sticks and/or your #11
blade (Ask your instructor for assistance when using the #11
blade for this technique). Apply seam filling putty as require
correcting any imperfections that are visible and let dry
until next class. The types and uses of seam filling putty
will be covered in detail in the next class.
ASSEMBLY TIP: Several light coats of putty (covered in detail
in 2nd Class) are advisable to cover badly misaligned seams
than one heavy coat. When completed the seam should not be
visible.
Homework: Mask the canopy frame for painting using the
supplied thin pre cut strips of masking tape. Complete the
vertical frame members only and bring to the next class for
painting. See the sample canopy
