A
few years ago, six to be exact, I fell heir to a book entitled "The
Men of the Gambier Bay", by Edwin Hoyt. It told the story of the
Casablanca Class Escort Carrier (U.S.S. Gambier Bay) and her crew.
The story begins with her launch in November 1943, and ends with
her loss in October 1944 with the Taffy 3 squadron at Leyte Gulf.
This book sparked my interest in the history of this class of carrier
and the role they played in World War II.
I began research to find any and all available information on the
Casablanca Class Carriers. Since none of this class remains today
(and it's been over 50 years since the end of the war), the task
was an uphill battle for me.
With
some help, I found a Survivor's Association for Taffy 3. After my
first contact with them, an avalanche of photos and information
started rolling in. A set of plans was obtained from "The Floating
Dry-dock". Several more books on Allied Escort Carriers were purchased.
By good luck, a set of micro-film records of the builder's original
plans was located and copies made. Then I made a trip to the Newport
News Maritime Museum to view their photo archives. This gave me
all the additional information I would need to build the model.
I
made the decision to build this particular ship because of all of
the help from the Survivor's Association and also because the U.S.S.
Gambier Bay was the only U.S. Navy Aircraft Carrier lost to a surface
action during the war.
By
this time, I had put in almost two years of research on the model
and still not a single thing had been built yet.
The
next step, deciding what scale to build the model in, was almost
as complex a decision as the model building itself. After weighing
all of the pluses and minuses, I chose a scale of quarter inch to
the foot (1/48). This scale would allow me to show the maximum detail
and still be transportable. Overall, at 1/48 scale the hull would
be ten feet six inches in length with a beam of 16 1/4 inches at
the center.
Choosing
a stable material for the keel was the next very important step.
Because the keel would be over ten feet in length, several materials
were discussed, including metal. It was decided, for ease of construction
and fabrication, to use a one-piece section of old growth red oak.
Quarter inch thick, 7 ply marine plywood was used to build the 61
individual frames that make up the shape of the hull. Stringers,
reinforcement plates, and spacers were made from laminated pine.
Each of the hull frames had two 1/16-inch diameter holes drilled
through and centered above where the keel and frame interlocked.
Two laser pointers were then used to align the frames with the centerline
of the keel. This same system was used as all the stringers and
spacers were attached. The outcome was a level, straight, and strong
hull frame.
The
full sides and bottom were made from 11/32 inch plywood in 48 inch
lengths. Each end of the plywood panel was machined to 1/2 its own
thickness. This was done so that when it was attached to the hull,
it would form a lap joint where it met with the next panel. This
formed a very strong and secure joint. The shape and location for
the bilge keels were found and, using plywood, the basic shape was
glued to the hull. All glue joints were made with either CA+ Thick
or Yellow Carpenters Glue. Polyester resin over epoxy would not
properly harden and would also cause problems later on. Two coats
of 2 oz. Fiberglass cloth with polyester resin were applied to the
hull. A light sanding was done between coats. After the second coat
set-up, the hull was wet sanded, any imperfections were filled in
and sanded, and a third coat of polyester resin (only) was rolled
on. The hull was then coated with resin on the inside. Next, the
entire hull was wet-sanded smooth and primed. The entire hull was
primed and wet-sanded a total of six times using a different color
primer between sandings to locate high and low areas.
During
the building of the hull, many detail fittings, accessories, and
radio components were located and purchased. For the fittings that
were not available, masters were scratch built and RTV molds were
made. During the building of the Gambier Bay, over 100 RTV molds
were made.
As
the hull was now complete, it was time for the installation of the
propeller shafts, stuffing boxes (with roll bearings), struts, and
rudder. Two 12V 3700-RPM Pittman ball bearing motors were selected
to use as drive motors. They were connected to the propeller shafts
with a 2 to 1 belt drive. For speed + direction control, 2 M.C.D.
SC330 speed controllers were used. For power, (2) 12V 18 AMP jell-cell
batteries were located in the hull.
The
hull was placed into the water for the first time at this stage.
Based on the weight of the materials to be used for the gallery
and flight deck, as well as the island and also because of their
height from the waterline, a center of gravity was calculated. It
was found that the center of gravity was located too high in the
hull and would tend to make the hull roll over. An additional weight
of 62 lbs. was added to the center of the hull along the keel. This
lowered the center of gravity and centered it along the keel In
order to get the hull to the proper waterline depth; an overall
displacement equal to 245 lbs. was required. It was decided that
something other than dead weight was needed for ballast. Water tanks
were built into the hull along both sides of the keel and below
the water line. Two additional 6-inch diameter tanks were added,
centered along the keel as one gallon of water weighs 8 pounds and
there is 231 cubic inches in a gallon it was found that the water
tanks would have to hold 15 gallons of water. Four RV water pumps
were used to pump the water into the tanks and then back out. This
removable ballast makes transporting the model much simpler and
safer.
Testing
the water ballast system showed that the hull was very stable and
the roll tendency was completely controlled. Using the (4) RV pumps,
it takes approximately 4 minutes to pump in the water and the same
to pump it out.
With
the hull now complete, the construction of the gallery deck and
flight deck began. The gallery deck was built in three sections:
the open bow section, the closed center section, and the open stern
section. Details of the exposed flight deck supports in the bow
and stem sections were constructed using polystyrene plastic sheeting.
The
basic construction of the gallery deck included red oak frames with
1/8 plywood covering. The 1/8 plywood also serves as the base for
the flight deck. Over 1,000 individual pieces of the plastic sheeting
were used to build the flight deck supports in the open bow and
stern areas. The gallery deck pieces were then primed and painted
before being attached to the hull. The bow section was epoxied into
place on the hull. The center section and the stern section are
screwed into place and are removable.
The
flight deck consists of 1,083 individual planks with tie-downs spaced
along the flight deck. Assertor Cable mounts were molded and glued
into place (along with the crash barrier supports).
The
catwalks, supports, anti-aircraft gun positions, and catwalk decking
were constructed from sheet plastic. The catwalk decking itself
was hand drilled to match the perforated decking of the real ship.
Over twenty thousand holes were drilled using a pin vise. At this
point, the island and mast assemblies were constructed. The island
is built entirely of sheet plastic. The mast is constructed using
a combination of sheet plastic and brass. The brass was used for
strength and durability. Hollow square tubing was used for the main
supports. All wiring for lights, radar, and sound are run through
hollow tubes. A twenty-pin computer plug is used to connect the
island/mast assembly to the power system. This makes the island/mast
assembly remove able for transporting.
The
paint scheme is Measure 32/15a, and is in the style of the last
known paint scheme that the Gambier Bay carried. It was a combination
of pale gray (S-P), light gray (S-L), ocean gray (S-O) and black.
The decks were painted deck blue (20B). A large black "73" was carried
on the forward end of the flight deck. A dulling agent was added
to the paint for the necessary finish.
The
2Omm anti aircraft guns are resing kits from Simar and the 4Omm
anti aircraft guns are resing kits from the "Quartermaster".
The
aircraft on the flight deck represents VC-10, the composite squadron
assigned to the Gambier Bay at the time of her loss. The aircraft
onboard the model are Plastic Kits from Tamya, Monogram, Accurate
Miniatures and Revell. Each plane has and operating propeller.
The
crew figures on the model represent the entire crew. They were all
made from 10 original figures that were molded. Then they were re-positioned
and hand painted (with my wife, once again, pitching in). There
are approximately 100 figures total on the model.
From
start to finish, the model construction took just short of 6 years
(a total of approximately 9,125 hours). In turn, the building of
the original U.S.S. Gambier Bay took a total of 171 days from keel
laying to commissioning.
To
date, the model has won Best of Show -Boat at the WRAM R/C Show
in White Plains, N.Y. It also won Best of Scale and Best of Show
at the Weak Signals R/C Show in Toledo, Ohio (both in 2001). I am
a member of the Buffalo Model Boat Club (which meets once a month)
and have been building boats for approximately 28 years.
Mr.
Balling plans on attending the September reunion and will bring
this model with him. Later this year, the model will be on display
aboard the USS Midway in San Diego for public viewing.
Mr.
Balling is a Senior Product Designer (Research and Development)
for the Eastman Kodak Corporation located in Rochester, NY. He holds
39 patents. Twenty-nine of those patents are for the Kodak "disposable"
camera.
