As different materials require somewhat different management, and even in the matter of wood alone this rule holds good, it may be as well to have some idea of what is meant by hard and soft wood. The young mechanic has most likely hitherto considered all wood under one head; but there is a vast difference, nevertheless, in the internal structure, even of such kinds as grow in England; and the woods of foreign countries differ again from these, some being of such close texture that it is almost impossible to work them with ordinary tools, and some (such as the palm) being little else than gigantic ferns, and in structure like that much-dreaded implement of flagellation—the schoolmaster’s cane. In England the hardest wood found is that of the box-tree, the chief place of which is in Surrey, at Box Hill; it The grain of boxwood is so close and even that it is one of the most valuable turning materials we possess. It takes excellent screw-threads, provided they are not too fine; is a very general material for boxes of all kinds, and also for chucks, although there is really no reason why it should be wasted in so applying it, when other woods of less value make such efficient substitutes. Probably its use for this purpose arose from the facility with which a screw can be cut in it to fit that on the mandrel, and that it is so hard as not to allow the collar beyond the screw to make much impression upon it. In consequence, when it is well fitted, such a chuck can be screwed on many times Somewhat similar in texture, though by no means generally used, is the wood of the Elder, which is quite different, be it observed, from the Alder, although I often hear the names confounded together. The wood I allude to is that of the tree which bears umbels of sweet, white blossoms, which give place to those jet-black berries we find upon them late in summer, and which are made into elder-wine, for home consumption at Christmas, when, no doubt, most of my readers have drunk it, hot and spicy and sugary, to keep out the wintry cold. From the same tree are commonly made those harmless engines of mimic warfare—pop-guns! If it were not for the presence of the pith, which is in fact the very quality which makes it valuable to boys for the latter purpose, this wood would certainly have been eagerly seized upon by turners. Even with this defect, it is used instead of box for the inferior kinds of carpenter’s rules and other purposes, and the larger pieces will make very good chucks, if a little care is exercised to prevent splitting them. It is indeed a wood that might be far more extensively used in this way than it is. The Yew, perhaps, should come next in order, for this too Walnut varies considerably in quality, some being harder and richer in grain than others. This wood, however, is not to be classed among those which are properly speaking hard, as it can be cut with ease, and can only be planed and worked as deal would be, viz., with the grain; whereas the hard woods work with almost equal facility in either direction. This indeed in a great measure constitutes the difference between soft and hard woods, in the turner’s sense of the words. If you were to hold a chisel flat on the rest, so as to let it scrape a cylinder of wood as it revolved in the lathe, you would find in some cases that it would tear out the fibres in shreds—these are soft woods. In other cases it would leave the surface rough but otherwise tolerably even, and with some it would leave the same fairly turned. I cannot call to mind any English wood but box that can be turned by a chisel held so as to scrape it, but the greater number of foreign woods are always turned in this manner, being hard and close in the grain. Birch.—Oh, once-dreaded tree! birch! with its long, swaying, switchy boughs, drooping as in sorrow at the mean uses to which it was applied! It is nevertheless a very Beech, which is a common and excellent material for the essays of beginners, who can turn tool handles especially from the small trimmed billets of it which are kept by the chairmakers, and which can generally be bought for a trifling sum in any town, and in many villages. If not, the wheelwright may be applied to for a supply, as he uses it rather extensively for the felloes of his wheels. It is peculiarly liable to the attacks of the little worm, weevil or maggot, who drills such innumerable and such beautifully round holes in furniture that stands long unused. Beech is often used for the screws of carpenters’ benches, as it takes very well a thread of such size as is required for that purpose. It will also, for the same reason, answer very well for chucks, for which it has the recommendation of cheapness and toughness. Ash seems to come next upon the list. It is probably the most useful of all English woods, and where toughness, pliability, with moderate hardness, are valuable qualities, no English wood can exceed it. For frames of carts and Oak is little used for turning, the grain being too coarse. The young mechanic need never make use of it for this purpose, and the same may be said of the elm. Elm is, nevertheless, used by turners for the wooden buckets of pumps, and is a generally useful wood. Bulk for bulk, it is lighter than beech, and it makes a good material, it is said, for lathe beds, though beech is more frequently used. It will answer for chucks, as indeed most woods will that can be cut into screws; it is very tough. Evergreen Oak, or Holm Oak, as it is called, is very different to the forest tree, and might be classed among shrubs. When dry, it is by no means a bad wood to turn, and will take a good screw thread, and make excellent chucks. Acacia is an excellent wood. It is of a yellowish brown colour, tolerably hard, and will take a good polish. It is Sycamore is white, very soft until old, when it becomes much harder. This is also a turner’s wood, and used extensively for wooden bowls, backs of brushes, turned boxes, and what is generally called “turnery.” A little of this will be useful to the young mechanic. It will make excellent bread platters, stands for hot water jugs, and such like. Holly.—The Christmas garland, with its red berries decorating even the poorest homes in midwinter, is a tree well worth the attention of the young mechanic. It is his substitute for the more precious material ivory, and from it he will turn the white draught or chess men, boxes, and many small articles. But it is necessary that this material should be perfectly dry, and to get it in perfection, carefully preserved to insure its whiteness, it will be generally necessary to procure it ready for the lathe at some lathemaker’s, or at first-class cabinetmakers’. If cut green, it requires long seasoning, during which it shrinks considerably. In fact, it takes some years entirely to rid it of the great quantity of moisture which it contains. It is well worth procuring, nevertheless, for it is nearly as white and free from grain as ivory. Many of the fruit-trees of our orchards and gardens supply good material to the turner. Apple, Pear, Pear has a very fine, even grain, and is largely used for making the curved templates (or patterns of curves for architects and engineers); it will make good boxes, and is fairly serviceable to the turner. Its colour is light brown, but darkens by exposure. The Plum has a wood veined very like that of the elm, but is a finer and better wood for the lathe. This is the wild plum, and not the grafted fruit-tree of our gardens, which is not nearly so good. The wild plum is excellent for small boxes, and looks well when nicely turned and polished. Cherry is a very excellent wood, and naughty, fast boys, who take to smoking, like young Americans, when they ought to be filling their young brains with knowledge instead of narcotics, know very well that it is made into pipes and stems of pipes. Happily this is not its only use, for it is fit for many other purposes; and for light, elegant furniture, it is scarcely to be equalled. Dipped in lime-water, it darkens, and by doing this here and there, a beautiful mottled appearance is given to it. It takes an excellent polish, and should be among the stores of the young mechanic. We now come to another soft, white wood. The Lime, Willow.—This is even softer than the last, and will plane into long, thin shavings, which are made into hats. (Once on a time I should have said “and bonnets,” but in these days no one would recognise such articles. They are fast fading out of existence; but I think quite as much sound sense used to be found under them as is now found under the very inefficient substitutes worn by ladies of the present day.) This wood will, of course, turn very easily, but requires very keen tools. In fact, sharp gouges and chisels are invariably necessary for soft wood turning. Get some dry willow by all means, if you can. The last wood of English growth which the young mechanic is likely to meet with is the thorn. This grows HARD WOODS.All those woods, properly called hard, including the best box, are of foreign growth, mostly coming from the Tropics. I do not know why they should be so much harder than those of temperate climes, but so it is. There are, however, woods in New Zealand, of which the temperature is similar to that of our own country, which are also exceedingly hard and difficult to work. A very large number of foreign woods are yearly brought to England in logs or billets or planks, some of very large size, and all of great weight. They are mostly liable to one defect, viz., rottenness of the core or heart, which limits the size of the pieces which can be cut from them. They can all be procured from the London lathe and tool shops, and there are also dealers in these woods (Jacques of Covent Garden, Mundy & Berrie Ebony, of which there are two or three kinds, some harder and more close-grained and blacker than others, and one which is called green ebony, which is like lignum-vitÆ (an English wood, but which grows to a larger size abroad; indeed, many so called English woods are not really so, but have been brought from other countries to be grown here). The general colour is green, but the veins are rather darker. Bowls and skittle-balls are made of it. It is not, however, of the same general use as the black ebony, which is very largely used both for cabinet-work and turning. Black Ebony is very close and hard, and, of course, proportionately heavy. It splits readily, but when chopped, the chips come off more like charcoal, showing no consistency. This is the kind imported from the Indies, and especially from Madagascar and Mauritius, and is the best for all kinds of turned work. Portugal affords another kind, which bears the same name, but is more brown than black, and softer, less compact in grain, and generally of less value. Ebony will bear eccentric work, and all kinds of beautiful carving and ornamentation in the lathe. Rose-wood is very commonly used for furniture and turned work. It is a rich red wood, grained with black. It is not very hard, less so than ebony, and has more evident grain or fibre. It turns well, and some pieces are very handsome. African Black-wood is in appearance similar to ebony, but it is even more close and compact, and is the most valuable of all to the ornamental turner. When this or ebony is set off by being inlaid with ivory, or even holly, it is very lovely in its intense and brilliant blackness. Either this or ebony is used for black pieces for the chessboard or draughtboard, though stained boxwood, being less costly, is sometimes made to take its place. African Cam-wood is a very beautiful material when first cut. Its rich red tint is diversified with the most brilliant yellow streaks. Unfortunately, however, these are not lasting. Exposed to the air, they gradually become darker, until they become red like the rest of the wood. This material, however, has a fine, close grain, is a genuine hard wood, and of general use to the turner for ornamental articles of various kinds. Tulip-wood is not very hard. Cut across the log, the appearance is fine, owing to the rings of growth being wavy and irregular, in dark and light red alternations, that reminds one of the flower after which it is called. This tree, indeed, which grows to a large size, bears flowers Partridge-wood is a nice, hard, and very pretty wood, rather dark or gray. The fibres seem to run both ways, giving a mottled appearance when turned. Coral-wood is bright red, hard, and close in grain, well suited for red chessmen, where that colour is preferred to black. It looks very handsome in the midst of other coloured specimens; otherwise, like all material of one tint and free from veined lines, there is too much uniformity of appearance to make it pleasing to the eye of one who is gifted with appreciation of colour. It is not necessary for me to go in order through a long list of foreign woods. The very young mechanic, unless living in London, will seldom meet with many of them; and a very good selection for the advanced turner will be composed of the following:— Black Ebony. Cocoa or Cocus, which is not the cocoa-nut tree, this being a palm, the wood of which is stringy like a fern or a cane; whereas, cocoa or cocus is firm, hard, and excellent. Black-wood, which cuts finely with tools for eccentric work. King-wood, a good and useful wood, something akin in appearance to rosewood. Satin-wood, pale yellow grain, like watered silk, turns very well, but is by no means hard; there is also a red satinwood. Rose-wood, already described; it loses colour after exposure, and is most beautiful newly cut. If the above are added to the most useful of the English woods described above, it will scarcely be worth while to add to them except as specimens. It is, however, very interesting to collect and arrange these, and it is an employment well worthy of the attention of the young mechanic. Thin slices cut across the grain, and sometimes, or in addition, slices cut with the grain, should be arranged in order after being trimmed to shape (round, square, or triangular, or even six-sided). They should be very carefully polished to bring up the grain, and labelled with the common and Latin (or botanical) name. The country from which procured, with short notes relative to the size and general growth of the tree, should be added. This will compel inquiry, and a great deal of information will be thus gained and stored up. A similar collection of English woods may be made, and, of course, with much greater ease. It will be observed that I have said nothing of the pines, deal, and larch. They are extensively turned in the lathe, Whenever you have time to spare, and are not inclined to turn, yet feel disposed to wander into your workshop, it is a good plan to trim and prepare pieces of wood for the lathe. You need a chopping-block, which is the end of a stick of timber sawn evenly across, and stood up in some out-of-the-way corner where chips will not be much in the way, and a light axe or adze, which latter is said to be the best. It is called the bassoohlah or Indian adze, but I never had one, nor ever saw it mentioned, except in one very excellent book by the late Charles Holtzappffel of London, who, indeed, keeps these tools. But a light axe is For finally trimming up short pieces, a peculiar knife is used by the lathe and tool makers; and when you can spare the money you should get one, as you will find it easy to use, and it will save you many a cut from the axe. In fact, I never advise very young mechanics to make use of the latter tool. It requires practice, strength, and a good deal of skill to use it well; and nothing is more easy than Another useful and easily-constructed apparatus for the preparation of long pieces is the shave-stool, used by coopers and chairmakers to hold the pieces securely while they are being shaped by the double-handled shave or drawknife, as it is often called, a tool omitted from our list, but very useful all the same. This is sketched at B, Fig. 43. It is often very roughly made, the chief necessity being that it shall be strong. It answers also for a sawing-stool. Upon the stool or bench, A, is fixed a sloping block, B. A swinging frame, C, is hinged or pivoted at D, so that if the lower part is pushed back from left to right, the upper cross-bar, E, will come forward and almost touch the highest part of the sloping block, B, so that any piece of wood, such as F, will thereby be pinched and held tightly ORDER AND ARRANGEMENT OF TOOLS.I must say a word or two as to neatness and order, especially in the arrangement of tools and appliances for the lathe. Whether you have a dozen tools or a hundred, always put them in the same place, so that any particular article can be found instantly, no time being wasted The strips for the holes should be about 2 inches wide, the lower one, for the larger chisels and gouges, rather wider than the upper ones. Sometimes these tool-racks are fitted up inside a cabinet, whose doors have similar racks; thus all can be shut in out of the reach of dust and dirt.
