November 12, 2006 The Goods A Nautical Tribute, Framed in Plastic By BRENDAN I. KOERNER ACCURACY is everything to die-hard builders of plastic models. After a hobbyist spends hours fiddling with teeny plastic bits and globs of noxious glue, his heart can break upon discovering that his miniature car's doors weren't made precisely to scale, or that his footlong frigate has fewer guns than its real-life inspiration from the War of
1812.
The model manufacturer Revell-Monogram thus designs its products with exceeding care. The company said its new model of a Gato-class submarine, a mainstay of the United States Navy during World War II, took two years to develop, as designers sweated over details that sound arcane to all but aficionados.
"The shape of the propeller, that was one issue," said Larry Lyse, senior director of engineering for Revell-Monogram, a division of the Revell Group of Northbrook, Ill. "We had to make sure the arc and the curvature of the blades are correct." Miss the exact curvature by a measly few degrees, and fussy customers might flood the Internet with complaints.
Revell-Monogram's take on the Gato-class submarine is notable not only for its fidelity to the real thing, but also for its gargantuan size. The model measures 52 inches from bow to stern and has nearly 300 individual parts. It is intended for the expert builder, the sort who might attend the annual convention of the International Plastic Modelers' Society.
The Gato model was conceived at the modelers' society meeting in Phoenix in 2004. The German unit of the Revell Group had just released a model U-boat, at 1:72 scale. Several Revell-Monogram customers told Edward F. Sexton, the company's vice president for new business development, that they would appreciate an American counterpart.
The celebrated Gato-class submarine was a natural choice, though mimicking the U-boat's 1:72 scale would produce a model the size of a
9-year-old child. (Revell's model of the aircraft carrier U.S.S. Enterprise, by contrast, is scaled at 1:400 and is just 33 inches long.)
The first phase of the Gato model's development consisted of homework. Mr. Lyse and his engineering team pored over submarine photographs, and one researcher was dispatched to the Wisconsin Maritime Museum in Manitowoc, where the U.S.S. Cobia, a Gato-class submarine, is moored on Lake Michigan. Members of the modelers' society sent in vintage pictures of subs in dry dock, to help in the design of the underside.
Despite the designers' diligence, compromises were inevitable. "The ships kept changing from mission to mission," Mr. Lyse said. The most troublesome issue was where to place the guns, because they were often moved from one part of the deck to another. A definitive answer was impossible - and Revell-Monogram hopes its more demanding customers will appreciate the problem.
After completing a so-called exploded drawing, which illustrates every model part, the designers sent their specifications to Revell-Monogram's Chinese factory. Steel molds were created, and occasionally refined when the company's testers found the resulting plastic parts too flimsy or prone to leave microscopic gaps in the submarine's huge hull.
A final version was sent to a professional model builder, who gave his approval before an assembled Gato was shown to the public at a hobby show last month.
The Gato model kit, at $99.95, is to go on sale this month. Mr. Sexton said that Revell-Monogram products were available in about 3,000 stores nationwide, but that the Gato would initially be carried by only a third of those - mainly at retailers, such as the Hobby Lobby chain, that cater to serious builders.
Because these consumers tend to be sticklers for historical accuracy, Revell-Monogram is also selling surplus Navy chambray shirts for $12.95
- "the perfect modeler's shirt when building your Gato-class submarine," the company's Web site says.
The most devoted builders, however, will still have to supply their own white hats and bell-bottoms.
