I guess I'd start by saying that, in my opinion, there are differences all right but not as many as some people seem to think. And I don't think there's any inherent qualitative difference between a plastic ship model and a wood ship model. Some wood ship models are far more accurate, and demonstrate far superior workanship, than some plastic ship models - and vice versa. When it comes to kits, I've often made the observation that (a) most plastic sailing ship kits are garbage, and (b) most wood sailing ship kits are worse.
I'm troubled by the common perception that "plastic modeling" and "wood modeling" are different hobbies. There's no reason for them to be so. If they would take the trouble, modelers on both sides of that artificial fence would discover that they have a great deal to learn from each other. I don't think of myself as a plastic modeler or a wood modeler; I think of myself as a ship modeler. (Except on those occasions when I'm working on an airplane, or - more rarely - a railroad car.)
I worked my way through grad school in a hobby shop that catered to lots of different hobbies. It wasn't a big store, and (especially in the summer) I had some idle time on my hands. I spent much of it browsing through catalogs and products, partly to get more familiar with the stuff I was selling and partly in the hope of finding stuff that would be useful for my own models. Among the tidbits I picked up:
- HO scale lumber, in the form of either basswood or styrene, provides a huge variety of shapes and sizes that are extremely useful in ship modeling.
- HO railroaders have access to a huge variety of beautifully-molded miniature figures. HO scale is 1/87 - slightly larger than the common ship scale of 1/96. Many Preiser HO figures scale out to about six feet tall on 1/96 scale.
- Model aircraft and railroad manufacturers make all sorts of decals and paint colors that are extremely useful in ship modeling. So do armor manufacturers. (Those cryptically-named shades of brown used to camouflage tanks and airplanes work perfectly well for wood shades on ships - or railroads. But lots of model railroaders in those days thought there was only one shade of brown on the planet: "Roof Brown," by Floquil.)
- Model railroad companies like Grandt Line and CalScale offer lots of brass and styrene detail parts that have nautical applications. (Check out such things as nut-bolt-washer castings and dummy turnbuckles.)
- Sheet styrene, a staple material for airplane, railroad, and armor modelers, is also an extremely versatile material for ship modeling.
- Butterfly collectors use extremely fine steel "insect pins" that come in handy for lots of purposes in ship modeling.
- Sable and synthetic-bristle brushes found in arts and craft stores are often cheaper than those sold in hobby shops, and work just as well if not better.
- Craft departments sell a huge variety of glass and ceramic beads that come in handy for such things as parrel trucks.
- Local hobby shops are unlikely to stock Bluejacket "Brass Black," but are far more likely to carry various chemicals designed to blacken brass parts on locomotives. It's the same stuff.
And so on.
I sometimes get a little amused at how hobbyists tend to get in ruts, and to be nervous about using new techniques and/or materials. I've known lots of scale aircraft modelers who are literally afraid to make things out of wood. Model railroaders use wood all the time - but it's almost invariably basswood. Serious ship modelers know that basswood is nice stuff for some purposes, but not so good for others. When was the last time a Model Railroader or Railroad Model Craftsman suggested making something out of boxwood, holly, maple, or cherry? Ship modelers know those are great woods for lots of purposes. They'd be just as useful in model railroading - or model airplane building. (Lots of WWI airplane modelers replace kit-supplied wing struts with scratchbuilt styrene ones. Why not wood?) And too many sailing ship modelers recoil at the thought of making anything out of styrene. Why?
One of the most irritating aspects of the hobby world, in my opinion, is the all-too-common tendency of hobbiests to sneer at people who approach their hobbies differently. I know of far too many self-proclaimed "tall ship modelers" who hold plastic kits in contempt. (Such people often have no idea that the hideously expensive continental European wood kits on which they dote bear scarcely any resemblance to real ships. Examination often reveals that those people actually know scarcely anything about ships - and have no idea what plastic scale modeling is about.) I've also been to model competitions in which the airplane modelers didn't bother to look at the ship models, and the ship modelers didn't condescend to look at the armor models. And, for that matter, modern warship modelers who referred contemptuously to "those stick-and-string guys." When I go to a model exhibition I try to admire - and learn something from - everything that's being exhibited.
I built my first model (a disastrous Revell DC-7) in 1956, when I was five years old. I guess I can claim membership in the first generation that grew up in the age of the plastic kit. I find it sobering that this is my fiftieth year as a model builder. On the other hand, I get a good bit of pleasure from the realization that so far I've only learned an extremely small percentage of what can be learned about model building. Ten years or so down the road I'm going to retire and, I hope, spend a good deal more time in the workshop. I suspect by the time my eyesight and finger muscles give out I may - may - be ten percent of the way toward a total knowledge of the subject. I find that thought stimulating.
I'll cheerfully concede some Basic Truths about model building. One - all other things being equal (as they rarely are), a scratchbuilt model represents more work, skill, and knowledge than a kit-built model. Two - all other things being equal (please remember that caveat at all times), a model on a smaller scale represents a higher level of workmanship than an otherwise identical model on a larger scale. (I can think of some exceptions to that one, but I think it's generally true.) Three - freshly-cut wood smells better than freshly-cut styrene. Beyond those profound observations, my opinion is that each modeler ought to feel utterly at liberty to pick his/her favorite subjects, techniques, materials, and stylistic approaches, and have an appropriate amount of respect for everybody else's. End of sermon.
