"CRAFTSMAN" vs. "SHAKE THE BOX"
To the newcomer to Model Railroading the mere mention of the phrase "Craftsman Kit" seems to indicate the modeller needs a degree in structural engineering and ten thousand dollars worth of tools. Nothing can be further from the truth.
The term "Craftsman Kit" came about in the mid 1950's with the coming of injection molded plastic kits. Old time model railroaders had been used to building primitive kits made of wood, cardboard and sometimes castings using a material made of lead and zinc called "Zamac". Kits consisted of some rough cut wood and templates, along with crude instructions (by todays standards), but even with these basic materials some "craftsmen" were able to construct good looking, realistic accurate models.
When companies such as Revell, Lindberg, Aurora and others began to make models of injection molded plastic, the kits were scoffed at as being too simple and "shake the box and the kit is assembled" type kits, thus the term "craftsman kit" came into use by the modelling press to describe the earlier simple kits. Unfortunately the term has stuck.
The technology used in injection molding has changed little in the past half century and many kits by these early manufacturers are still available to-day, allbeit by different companies.
Wood kits on the other hand have changed dramatically over the years. With the latest development being the use of laser cutting, wood kits are now as easy to assemble as many of the injection molded kits, and make a much more realistic model. In addition the wood kit is much more distinctive as there will not be hundreds of thousands made as is the case with injection molded kits.
Every KANAMODEL kit includes the sheet "WORKING WITH WOOD" and for the benefit of the newcomer we have reproduced this below. We hope you will read it and that this will be the incentive to try one of these realistic models made by ourselves or any of the other wood kit manufacturers.
WORKING WITH WOOD
Mention a wood model kit to many modelers, (sometimes very experienced modelers)
and you will often get the comment that "I can't build wood kits". The
fact is that before the advent of the plastic injection molding machines in the
1950's most kits were wood or cardstock, and many very good models were built in
this medium.
Plastic kits have certainly played a big role in making model
railroading the popular hobby it is to day. They are of great use in making a
number of structures quickly, but the drawback is that they are in reality one
of a million kits and no matter how much kit bashing is done they still suffer
from the sameness syndrome. The painting and decorating of the model is the only
thing that will make the model different from all the others. Also because of
the high cost of injection molding dies, very few specific prototype kits are
available, and instead virtually all kits are generic in nature, whereas with
wood kits extremely accurate kits of specific prototypes can be produced because
the kits need not be manufactured in huge quantities. These differences in
production runs also explain the differences in pricing between the two types of
kits. The research, development, design and engineering of any kit is the major
part of the cost and in the case of a wood kit must be amortized over far fewer
kits than if the kits are produced in plastic. Like
most other areas of our hobby, wood kits have developed a great deal in recent
years and with a little time and patience all but the most
complicated
kits can be assembled by the novice with little previous wood building
experience. What follows is a basic discussion of what you will need to know if
you are a first time wood builder but have had experience in plastic.
First of all and probably most important is TAKE YOUR TIME. Your wood
kit will not go together as quickly as a plastic kit, nor is it intended to. You
will spend many more enjoyable hours on your wood kit and the end result will be
much more satisfying. You will be able to say with pride that you
"built" the model, not just put it together. Most wood kits are built
using a series of sub-assemblies. Study the instructions carefully before
starting to determine where these sub-sections are and you can then work on a
second one while the glue or paint on the first one is drying. Again we can not
stress enough that you understand and follow the instructions carefully. The kit
manufacturer has spent many hundreds of hours developing them, and the vast
majority of problems with kit building comes from the builder not adhering to
the written directions.
The tools you will require in constructing your wood kit are very
basic but extremely important. First and foremost is a good quality knife. By
far the most useful is an #1 knife holder and a #11 blade. Several
manufacturers make this type of knife and blades. You should also have a few #17
chisel type blades for the same knife. A #5 knife handle along with a fine tooth
razor saw blade is also a necessity. Just an observation here on cutting - a
sharp blade is absolutely necessary. You will never get a good clean cut with a
dull blade, for the blade crushes rather than cuts. When cutting larger pieces
over 1/16" square, always use the saw blade as it is impossible to get a
square cut with a knife on larger pieces. In cutting stripwood, it is a good
idea to cut it slightly longer than needed and then lightly sand until you get
the exact length. When cutting stripwood cut against a hard backing such as a
smooth piece of hardboard or Masonite. Never try to cut on a mushy surface such
as cardboard, etc. A final note regarding cutting stripwood - most kits use
color coding on their stripwood. When cutting part of a wood piece, always start
from the uncoloured end, so that you will have the colour available until you
have used the last of the piece.
Many models will use such items as nut/bolt/washer castings, railings
etc., which require tiny holes to be drilled in the wood. A hand held pin vise
is a necessity along with an assortment of 60 to 80 drills. Don't attempt to use
one of the power drill attachments for this job, as they are impossible to
control on soft wood. Another item of necessity is a good quality scale ruler
with a straight steel edge. This is a must for any modeling job in wood or
plastic and you will have it for a lifetime. Instructions will often call for a
scale measurement and although they may give the metric equivalent this is not
as accurate as using the scale measurement.
Sandpaper is another important part of the modeler's toolbox. An
assortment of 120, 240 and 300 grit papers should cover all your needs. Emery
boards available at drug stores for manicuring fingernails are very useful. They
can be cut to any shape and are great for enlarging window openings, etc.
Most stripwood is now "fuzz free" but it is still a good idea
to "de-fuzz". To do this fold a piece of fine sandpaper between your
thumb and forefinger and pull the stripwood through it. While we are dealing
with sanding don't try to sand with the sandpaper loosely wrapped around your
finger. Always attach it to a small squared block. Alternately place the
sandpaper on a flat surface and rub the part against it lightly. Remember
sandpaper can remove a surprising amount of material quickly so go slow and
check frequently. You can always take off a little more but you can't add any
on.
Most of the other items you may need in constructing your wood kit are basic
modeling tools such as tweezers, small scissors, a magnifier, small wire
cutters, etc. Wooden clothes pegs are also very useful to act as clamps when
allowing cement to dry. Small alligator clips with the teeth filed off will also
make good clamps for the tiny parts.
One special item you will need is a good quality flat surface. I have
found a piece of hardboard or Masonite is best. I usually use one about 12"
x 18", In fact if you are working on more than one sub-assembly at a time
you will need one for each assembly so that you can leave it undisturbed while
you work on the second section.
There is no substitute for good lighting. You will work with many tiny
parts, and without a bright well lit area to work in it is impossible to see
what you are doing.
Some plastic parts can have a tendency to warp or bend over
time. This is particularly true of polyurethane parts. If this happens to a part
in your kit application of a small amount of heat while the part is on a flat
surface will cure the problem. We have found a hair dryer is a good source of
heat for this job. Allow the part to cool on the flat surface. Also parts using
materials of different composition, such as wood, card, urethane etc. will
experience some variation in size as these parts will expand and contract at a
different rate with different humidity and temperture. Always test fit parts
before cementing them in place and remove any small amount of material
necessary. We make most parts slightly oversize to compensate for this
difference.
Cementing wood parts is a different process than cementing plastics.
Cementing Styrene (the most common plastic kit material) is actually fusing by
melting the plastic and bonding them to-gether. Cementing wood is done by the
cement penetrating the wood cells and bonding by hardening. Testors, Ambroid and
others make solvent-based wood cement, both slow and fast drying. (If you choose
to use these types be careful of using the fast drying types as the faster the
glue dries, the weaker the bond). In the course of constructing a great many
wood kits I have found the best overall cement is the common white glue such as
Elmers, Lepages, etc. I put a small puddle on a piece of waxed paper, then apply
the glue using a toothpick. This enables you to get the glue into the area you
want without smearing it all over the place. The bond, if allowed to set
properly, is very strong even in small areas of contact. You will also need
contact cement to secure windows, doors and other plastic or metal parts. Use a
toothpick to apply this cement also. If your kit requires joining metal to metal
or metal to plastic, etc., you will also need ACC cement commonly called
"Super" or "Crazy" glue.
Painting and or decorating your model is pretty well straightforward.
Solvent-based paints such as Floquil, Accupaint, etc. can be used with no
necessity to use a barrier coat. The newer water based acrylic paints such as
Polyscale, Model Flex, etc. can also be used. As with all models it is best to
paint as much as possible before assembly especially where color separation is
necessary. Wood stain is a very common and effective way of finishing a wood
kit, but in this case it is compulsory to stain the parts before assembly. The
reason for this is that the stain will not penetrate anywhere where there is
glue, thus you will find an uncolored area around a glue joint when the stain
has been applied after the glue has dried. There are many commercial stains
available, but a very good weathering solution is to mix 10 parts of India ink
with 30 parts of denatured alcohol. This results in a good weathered look. You
can lighten or darken it by changing the amount of India ink in the mix. One
special note here however, when using the newer water based acrylic paints you
must be aware of the potential of curling especially on very thin wood or card
stock. This problem can be solved by undercoating with a solvent based under
coat or a light spray of clear lacquer or varnish. If curling does occur simply
re-moisten the part and allow it to dry under a heavy weight such as a book,
etc.
Before painting the plastic or urethane parts in your kit, they should
be thoroughly washed with a strong solution of dishwashing detergent to remove
the release film used in the molding of plastic or casting of urethane parts.
This is especially important if you are using water soluble paints on urethane
parts such as bases, foundations and some cast windows and doors etc.
So that's it. There is really nothing very complicated about a wood kit
as long as you remember the most important points mentioned above. DO read and
understand the instruction sheet fully before starting. If there is something
you don't follow write the manufacturer. Most manufacturers take pride in having
their kits built as designed and are more than happy to help with a problem. Be
sure to enclose a self addressed stamped envelope and leave space on your letter
for their reply. Finally be patient. Take your time. Relax and enjoy your work.
