At long last, some structures have begun to appear on the GIRR. Of necessity, most of the structures are scratchbuilt because its hard to find 1:29 or 1:32 scale kits. Also, the structures are all intended to be left out in the weather all the time, so that the construction techniques that are available are somewhat limited.
The first building to appear on the GIRR was this
little tin shack made from corrugated aluminum cans. At the
time that this picture was taken, the building had been outside for
about 2-1/2 years. During that time, its painted weathering had been
naturally weathered such that the artificial weathering had to be done
again. Other than that, it has held up well.
A JigStones farmhouse was the
second building to be placed on the layout. For the time being,
"placed" is the right term. No attempt has been made to integrated it
into the surroundings until a little more development takes place. For
right now, its getting naturally weathered. The Floquil paint used to
paint and weather the building is being weathered itself and the roof
is heavily faded.
The next structure was this warehouse also made from corrugated
aluminum cans. This structure covers an awful mess of wiring out in the
middle of the layout.
This set of storefronts is
a Mountains-In-Minutes polyurethane foam building front. The structure
has three walls and a roof. The buildings come with metal window frames
and cellophane window glazing. They are painted primer gray. The detail
on this inexpensive ($40) building is very good, I really liked the
moldwork. It is also quite sturdy as the walls are nearly an inch
thick. It is also acceptably close to 1:29 scale based on the door size
that I thought it would look good on a 1955 vintage 1/29 scale layout
as a 60 year old building.
Another building is this
set of building backs. The set is designed so that they can be glued
together into a single building but since they would not be visible on
the "back" side, I elected to leave the backs plain. The sidewalks on
both buildings were made from RapidSet cement cast in a wooden form
around the Wonderboard floor.
The backs were filled with WonderBoard, a concrete
and fiberglass product designed to back tilework. WonderBoard scribes
and breaks well and can be found in most homeowner stores. Another
piece of WonderBoard is used as a floor. Both pieces of WonderBoard are
glued in place with liberal amounts of Liquid Nails adhesive. Since
WonderBoard is very porous on the broken edges, I sealed the edges with
a layer of RapidSet cement.
WonderBoard worked out
well for me. I originally built this building in 2000 as a
test article with no intent of actually using it. By 2008, it had been
sitting on the GIRR all that time with only a little dirt on it to show
it's age. A blast with a hose took care of the dirt. Then I converted
it to a gas station.
WonderBoard had shown is ability to withstand the weather so I also
built a viaduct out
of WonderBoard. It was a quick and dirty project, but it came out well
enough.
With the success of the viaduct under my belt,
I launched on a long planned major project, a Santa Fe style mission
station. The project also came out well. I had intended the
building to be imposing, but I got a little more than I expected.
The
station needed some access, so I started building asphalt roads from
WonderBoard. These came out pretty well to, but I'm going to build the
next batch of roads with a different method.
I still
needed more structures, so I have built a hotel, also made from
WonderBoard.
The building uses pretty much normal WonderBoard construction methods. The windows are resin castings initially held in place with small drops of Zap-A-Gap CA at the corners. The glazing is clear styrene which has been "frosted" with a CA kicker. After the CA has dried, a fillet of plumber's epoxy is applied on the backside to seal the windows and to firmly adhere them to the structure. All access is via the bottom as the roof is firmly cemented in place, both to strengthen and seal the structure. The roof is sloped to the rear and drain holes and "downspouts" were provided to allow rain to drain off the building.
The base is a sheet of WonderBoard with a cutout for the driveway. The parking lot is A-1 Grit C-71 mixed with RapidSet (2/3 grit, 1/3 cement) and dry spread then wet down. A little more grit was spread on and held in place with TiteBond II and water (50/50). The "grass" is fine DG dry spread and bonded with TiteBond II and then painted with Rustoleum. The paint is thin in spots to allow the tan color of the DG to show through to simulate dead grass.
The ledges around the
building were formed from concrete skived to shape with this styrene
tool. Styrene makes a good skiving tool because it can be easily cut to
shape. If made thin enough, this one is 0.030" which is about right, it
can be simply flexed to break off the concrete that adheres to it.
Building the ledges was a two pass process. First a bead of cement if
formed by hand to the rough shape of the ledge and then the tool is
drawn down the bead to remove any excess. There will be low spots and
holes. These will be filled in during the second pass after the cement
from the first pass has set up. After the first pass has set, more
cement is added where needed and the the skiving tool is used again to
remove excess and to detect the remaining low spots that need to be
filled in. Skiving should be done only minutes after the cement is
applied or it will be too late.
On June 24, 2008 another building
appeared. This is a redwood barn purchased from Comstock Construction Company. I've
concluded that I don't want to scratch build everything. The building
needs a light coat of redwood stain and maybe a coat of water sealer.
The building didn't come with the foundation, I added that from
Jigstones flat block glued on with TiteBond III. Putting wood, even
redwood, directly on the ground is not a good plan.
The barn will cover and conceal the sprinkler riser that will eventually be a drip irrigation distribution point for that region of the layout.
The barn did receive a coat of redwood
stain and an overcoat of Thompson's Water Seal. The stain was one
intended for redwood outdoor furniture, it took care of the "white"
redwood. I initially started to brush it on, but it was hard to get in
the slots cut into the siding and around the details of the doors. I
did most of it with an airbrush so I could get the stain in every nook
and cranny. The water seal came in a aerosol can so it was just sprayed
on. We'll see what natural weathering does to this structure.
This is a JigStones house. I need a few
places for my townsfolk to live. JigStones are a little expensive to
get started with as the mold sets have become somewhat expensive, but
the incremental cost of building construction is quite low even though
the labor content is somewhat high. For outdoor use, I cast the blocks
in RapidSet concrete. I am using Liquid Nails to assembled it. I used
Liquid Nails on the farmhouse described above and it's been out in the
weather for 10 years and it hasn't come apart. Lexel is actually a
better adhesive, but I didn't have any and Liquid Nails is cheap, about
$3 for a caulking gun sized tube.
The other JigStones work that I have done didn't start out on a base. This time I made a base from WonderBoard to start with and it made a significant difference in the ease of assembly of the structure. I could turn in on the workbench to work on the various sides without disturbing joints that hadn't fully set up. The base will also improve the structural integrity of the structure.
The
town needs a church and it looked like it would be an interesting
JigStones project. I assembled this one with Liquid Nails for Marble up
to the top of the sidewalls, then I ran out. The hardware store didn't
have any more of that kind so I used Liquid Nails Heavy Duty. This
stuff is actually easier to work with. It's not as stiff and spreads
better and sets up quicker. The slop from the adhesive doesn't actually
matter too much as Liquid Nails takes paint well and the slop doesn't
show after a coat of Rustoleum spray paint or primer. Anything that
does get on the front of the blocks needs to be immediately smoothed
and spread so that it doesn't mask the texture of the "rock work."
The church entry is a built up door that is attached to the front. The windows are glass cut to shape backed with photographs of real church stained glass windows printed on transparency material. The large diamond shaped window in the front is also a stained glass simulation, however the one in back is clear just to let in more light so that the rest of the stained glass shows up better.
The "grass" is a colored sand that I found at Cost Plus Imports. There is a little yellow mixed in with the green. There are more details of the construction at my JigStones Tips page.
There is one spot on the GIRR
branch line to the garage where a serious contamination problem has
existed for since the construction of the railroad. The area, and the
track that goes through it, gets covered in pigeon poop. This is not
only an unsightly mess, but the stuff causes derailments and power
pickup problems. I find that city regulations prevent me from shooting
or poisoning the pigeons so I have to live with them or risk a
fine.
The source of the problem
is an alarm box near the peak of my roof. I should go up there and put
some wire up or something to keep the pigeons off of it, but I'm not
climbing that far up a ladder to get to it. There have been pigeons
nesting there almost continuously for over 20 years.
One early pair of pigeons tried to make their nest from used nails. I kept finding rusty and bent nails, staples and other metal construction scrap on the walkway. They were apparently selectively collecting them from everywhere around. After a couple of years, that problem subsided as different pigeons took over the nesting site.
Instead, I built a snow shed to
protect the tracks from the falling guano. It is made in two 2'
sections and it covers the whole of the impacted track.
It only took one afternoon and the next morning to construct these sheds. They are made of milled redwood assembled with TiteBond III wood glue and nailed with a brad gun. The roof is crimped aluminum cut from steam tray covers and attached to a door skin subroof with Liquid Nails. The crimped aluminum is painted with a Rustoleum cold galvanizing spray which is really just a high zinc content primer.
The shed has been in service for less
than 24 hours and it's already taken some abuse for the good of the
railroad.
Not all the buildings on
the GIRR are scratchbuilt. This is an AristoCraft farmhouse. It looks a
little big for 1/29 scale based on the doors and windows, but it is a
good looking structure nonetheless. It is rated for outdoor use and is
fully assembled and painted. The model is built from heavy plastic. The
windows are glazed with clear thin plastic and the floor is partially
open.
The AristoCraft water
tower also came fully painted and mostly assembled. The water level and
spout chains need to be attached by the user.
The tower actually functions. It will actually hold and dispense liquids from a polyethylene tub inside. There is a valve that controls the liquid flow (accessible with the roof removed) but even if the valve is open, the contents will not flow out if the spout is raised. There is also a functioning water level indicator based on a couple of floating corks and a weighted chain.
Eventually, a scratchbuilt coaling facility will cover over the wiring in the background.
The next day, a couple
of more Aristo building showed up. This is the Gingerbread House. It's
smaller than the farmhouse and single story. It is, however,
illuminated. Inside the door, there is a switch. Two wires lead from
the bottom. The single bulb is mounted on a bracket that illuminates
the whole house fairly well. The bulb draws 45 mA and 18 volts.
The Aristo
Interlocking Tower was larger than I thought it would be but it fit
where it was intended. It is also illuminated on both floors. The bulbs
draw 135 mA at 18 volts.
The tower was intended to
cover this electrical conduit and it's associated wiring. I thought
that the floor of the tower would be open like the other Aristo
buildings, but it was solid.
However, with the
appropriate tools, anything can be hacked. I marked the floor
underneath with the extent of the area I could cut and used my Makita
recipro saw to cut out a hole in the floor. The floor itself is pretty
substantial. It is made of about 1/8" heavy crossbraced plastic (some
kind of phenolic based on the odor while cutting it), 1/4" of foam and
then a thin plastic formed sheet representing the floor. One of the
cutouts can be seen on the table.
