As opposed to most hobbies, ship model producing needs couple of highly-priced tools. Just about each household harbors the beginnings of a fine model maker's tool kit. The rest can be produced, improvised, and purchased as the function progresses.
Most significant of all tools to the maker of ship models is his knife. It may well be something from an affordable pocketknife to a higher-grade wood carver's tool. Cost and deal with style are unimportant as lengthy as its blade is keen and has the high-quality of taking and holding an edge. Lots of specialists rely on numerous kinds of “sloyd”or bench knives. Other folks use absolutely nothing a lot more than an ordinary jackknife, when nonetheless other folks really feel that affordable kitchen paring knives, ground and sharpened to easy shapes, are most effective suited to the function.
For the specific carving and whittling jobs that generally are necessary on models, as effectively as for the common shaping and roughing, the amateur can style his personal specially shaped knives from sections of discarded hack saw blades. Ground to shape, hardened and tempered, honed to a fine edge, and mounted in appropriate handles, they kind a single of the most helpful assortments of tools that the model maker can personal. To make a knife just grind off the teeth, and shape the finish. Then, as a preliminary to the tempering method, grind a single side vibrant or polish it with emery cloth.
Whilst you are polishing the blade, spot a flat iron bar in your furnace or forge and heat it till it becomes red hot. Choose up your knife blade with a pair of tongs or pliers at the deal with finish or tang and proceed to rub the blade more than the hot iron till the polished surface turns a light brown. Then promptly plunge it vertically into a pail or pitcher of water. Ultimately, give the blade its final grinding and sharpening. When grinding thin tools be cautious not to draw the temper. If you use an emery wheel, be confident to maintain the function cool by dipping it in water regularly.
If, throughout the method of shaping your knife, you will file a series of V-notches in the point opposite the cutting edge, you can furnish your self with an outstanding tool for marking imitation planking lines on the decks of your ship models. Grind the upper edge of your knife to a rounded point, file in ten or twelve teeth at the highest point of the curve, and then, working with a fine flat file, dull the points of the teeth slightly. Lines are drawn on the wood with a pencil and the tool moved back and forth more than the lines with a light stress. To make confident that straight lines will be accurate and uniform, you can guide the tool with a ruler.
Tiny gouges of numerous shapes and sizes also can be produced from discarded hack saw blades. The blade is initial softened by heating it to a dull red and laying it on a brick. Immediately after it has been permitted to cool, the teeth are removed with a file.
The gouge shape then is obtained by setting a vise to the appropriate width and driving the blade into the opening by pounding a lengthy, rounded wooden tool against it with a mallet. A further and possibly a lot more correct system is to use a swage block reduce to match the preferred curve of the gouge.
To stiffen the otherwise springy blade, the curved channel will have to run the complete length of the tool. The edge of the gouge, which has an inside as effectively as an outdoors bevel, must be shaped and partly sharpened just before it is hardened.
In hardening the tool, heat the blade to a dull red for about 1 in. of its length and, holding it vertically, plunge it into cold water. To temper it, brighten about 1 in. at the point and hold it more than a flame in such a way that the tool is heated at its middle. Watch the polished portion of the blade and, as quickly as a light brown or straw colour seems, plunge it into water. These must give outstanding knives for ship developing.
