Cat Scratch Fever - Superdetailing armor models
By Phil Novak
Sometimes all of us out there in the modeling world feel the need to do
something different, something crazy. We need to do something that no
one in their right mind would do. Some interpret this as doing "funny"
vehicles that were rare and have little reference to work from. My
interpretation is a little bit different, and it can be just as challenging. What I
like to do is take a fairly common subject, like one of the German cats, a
Tiger or Panther, and cram it with every last after market set that is
available, and scratch build every little thing that is not there that's
supposed to be. Now before one begins such a project it is important to
know that you need two things: time, as it will take a long while to complete
and most of all, reference. With a great amount of reference material it is
easy to see what needs to be done, and can provide ways to do it. Often times you will find a piece that was on
the real thing, but nobody provides it, or if they do, it doesn't have the proper shape. Not only does such a
project test your ability with after market materials, but also with scratch building and conversion methods.
So I have decided to take on a big project like this, I have a stack of
reference materials, a mountain of styrene, resin and photo etch, and
now where do I begin? First of all look at what you are trying to do.
Sort out your after market and decide where in the course of
construction do you want to install them. Mark up your instruction book
with notes on what you have a replacement for or what you want to
replace. Remember too, that you will want to highlight things that you
need to scratchbuild and add, or else you may forget until after
painting or weathering, "Hey I wanted to add some bolts here!" Put
words of warning such as "Don't attach until painted" and "Don't put
this on until later" It is also a good idea to go through all of your pieces
and decide the quality of them. Sometimes, the kit pieces look better than the after market ones! Once you are
done deciding which pieces you are going to use, which ones you need to scratch build, and which ones need
to be "tweaked" you are ready to begin
It is my experience that it is best to build the vehicle from the
inside out, and from the ground up. Start by putting the hull
interior in. Try and work in subassemblies whenever possible.
"Subassemblies" are the main components that come together
in the end. Examples are, a gun and gun breech, the interior
floor with the transmission and seats, an engine, etc. Never
glue in the subassemblies until you have painted and
weathered them. You will have to use your own judgement on what you want to glue in and what to leave
loose. But when in doubt, leave it loose! It always easier to glue it down when your done, then pry the whole
model apart trying to get to something so you can paint it. This is another good reason to mark your instruction
book, as it prevents blunders such as premature attachment. While you are doing this whole process, look at
what you are doing and ask yourself, am I going to be able to facilitate painting if I glue this on? Am I going to
be able to remove that subassembly for painting if I glue this on? Every once in a while, especially with
interiors there are little parts that need to be installed that throw a big monkey wrench in to the whole equation.
These parts are so tiny that it is hard to paint them separately but if you don't put them in, they won't allow for
something to be removed for painting. Examples are little boxes on a hull wall. You can't glue them in or else
you can't take out the hull floor, but they are not big enough to be a separate subassembly. Be careful not to
loose these and take your time with them, things like that can make or break an interior.
Now that you are satisfied with the interior assembly, put on the upper hull
and make sure that it fits nicely. Remember not to glue it on! If it doesn't fit,
you're in for some fun, and if it does, then you're lucky. If it doesn't, sit down
with it and see what is keeping the upper hull from sitting properly. Once you
figure it out you will have to find a way to grind it down, move it, or if it can't
be seen on the finished product, remove it. Removing should be a last
resort, because usually you will be able to see everything when you crack it
open. When you figure out what the problem is, the next thing is fixing it
without damaging too much detail. The best advice is, just play with it until it
fits. So once you are satisfied with the fit and assembly, you can go ahead
and paint it. If your subject is German, start by spraying the interior with a
reddish brown color, such as Tamiya XF-9 Hull Red, or if you are an enamel
user, darkened model master rust. Once you have this down spray the interior with XF-2 white with an
extremely small amount XF-9 in it. Just enough to give the paint a little tint. If you like enamel, use model
master panzer interior buff. Now you may be asking, "why red?" The answer is quite simple: The Germans
used a red brown primer before the white coat, which gave it a reddish, creamy white finish. The red primer
helps to bring it out a little better then just using the straight reddish white to begin with. So once this is dry go
back and do your detail painting. This can get a little sticky because there is no really good reference on
interior colors. As a general rule of thumb you can paint things such as the transmission a greenish white, a
gray or just leave it the reddish white. The same rules apply to the brake drums. Also I have heard that the
floors of German interiors were left primer red, so be careful when painting as to not cover the red in ivory. In
allied tanks, a straight white was used, maybe with a little bit of a greenish hue. Modern AFV interiors are
mostly a pale green.
Once you are done with the interior you can begin work on the engine or engine compartment. The engine is something that can make or break the model, so take your time when working on it. The engine is the biggest item to detail in the construction process. Since most manufactures don't bother with wires and tiny bolts, this is where your scratch building skills and eye for detail come in handy. Be prepared to spend some time on the engine, making sure that all the wires are attached and all are the right shape and length. Painting can be a little challenging, but take your time and it will come out nicely. The German engine compartment uses the same red brown base coat as used in the crew compartment (No white overcoat). Allied engine compartments were painted with the white. When you go to paint the engine itself, don't paint it with any metallic colors. Instead use flat black or a dark gray, and then lightly dry brush with aluminum.
By this time you should have everything on the lower hull
interior finished. Now build up the running gear and tracks.
Tracks are an item that can really bring your model to life. With
many different types of track available it can get a little
mind-boggling to decide which type is right for you. In my
opinion you can never go wrong with Friulmodel. They are the
best link track on the market, completely workable, and quite
easy to assemble. Unlike ModelKasten track, the links hold
together with incredible strength. Only when installed on the
model, do they really come alive, with that realistic sag between
the return rollers, or in the case of tigers and panthers, lying perfectly on top of the road wheels. Assembly is,
in most cases a snap, but a No. 76 drill bit, a small pair of clippers, and an X-Acto knife are essential. The drill
bit is to clean out the holes that the pin is inserted in. I just put the two links that I am assembling together and
then run the drill through. Then without separating the links, I push the wire in to for the pivot pin, and finally
clip the excess to get the pin flush with the hole. Repeat about 200 more times. I have heard about some
people using music wire for the pins instead of the provided soft aluminum. This prevents the wire from
bending when pushing it in the pivot point. Overall this is easily a five star product. ModelKasten Track also
works well but it does have an annoying tendency to come apart. Now you may be asking, is there really a big
difference between the poly (rubber band) track and the link by link track? The answer is yes, there really is.
Often times the link by link has holes in the track where there are really supposed to be holes, and the poly
track doesn't. At most it has indentations where they would be, if that. The guide horns are never hollow either.
The pivot point on the track is also much more noticeable with the link by link track too. Also the "sag" between
the return rollers is evident, but don't get carried away with this. On wartime photographs a noticeable but
slight sag between the rollers is present. This is one point in which your reference comes in handy. Use
pictures to determine the proper amount of sag.
Most of your resin parts are going to be used in the interior, and most photo etch is going to be used on the exterior. The most common parts are the engine deck screens, fenders, stowage bins, pretty much anything that was sheet metal. The advantage to using this is first the scale thickness of a part. The photo etch is much thinner then any plastic, so thin parts such as fenders look much more in scale. Another plus is the ability to battle damage it. It can be bent, twisted, punched, mangled, torn, and dented much more easily then any plastic.
If you are going to be doing a subject with Zimmerit, there are
many ways to do it. The Germans introduced Zimmerit in 1943 to
cut the losses of armored vehicles to magnetic mines. It is a
cement like substance applied in two coats during the production
of the vehicle. Made of Barium Sulfide and a few other materials
it was corrugated to cut down on the weight of the already heavy
vehicles. It is this corrugation that poses the difficulty of
reproduction in 1/35 scale. Fortunately Cavalier Productions
have come up with thin resin sheets that you glue on the surface
of the plastic to reproduce the unique texture.
To start get a sharp X-Acto number 11 blade and cut the desired section out of the sheet. Now comes the ugly part: you have to file off any surface detail on the model so the sheet will sit properly. Use an emery board for the smaller stuff such as rivets and an X-Acto blade for the big stuff. Carefully test fit on the model to be sure that it is approximately the right shape- don't worry if it isn't an exact fit, as they are made larger then necessary in order to cover the whole section. When you are satisfied apply CA glue to the edges of the sheet and put it in place. After the glue has dried take your no. 11 blade and trim off the excess. Finish off using an emery board to file it flush with the edges of the vehicle. Paint as usual.
