MANUAL OF THE HAND LATHE.

THE FOOT LATHE.

There are two distinct kinds of work done in foot lathes--the useful and the merely ornamental. Both afford enjoyment and profit to those who practise them. The mechanic who earns his living by working ten hours a day in a workshop, does not care to go home and pursue the same calling in the evening; but he can institute an agreeable change in his life, beautify his dwelling, and cultivate his taste, by the use of the lathe, and thus obtain ornaments that would cost large sums if purchased at the stores; or he may, indeed, make the lathe a source of revenue, and sell the product of his skill and ingenuity at high prices to those who admire, but have not the ability to construct.

To many mechanics, even, the lathe is merely a machine for turning cylinders or disks, or executing beads, ogees, scrolls, or curves of various radii, so that, after all, the work is pretty much alike, and ceases to be attractive. This is quite a mistaken view. There are no such goods in market as those made on lathes, and peculiar tools used in connection with them--by lathes with traversing mandrels, with geometric chucks, with dome chucks, and compound slide rests. There are lathes that, while one could chase up a five-eight bolt in them as well as on the simple pulley and treadle machine, are also capable of executing all sorts of beautiful things--vases with bases nearly square, or exactly square, with round tops and hexagonal bodies, with gracefully-curved angular sides and bases, fluted vertically; boxes with curious patterns, resembling basket work; in fact, any combination of straight and curved lines, cut in the sides, it is possible for an ingenious man to invent. Strictly speaking, these are not lathes, for in order to do the things before mentioned it is necessary to use after attachments in connection with them, so that the combination of them produces the results spoken of. There is, absolutely, an unlimited field for the genius of workmen to exert itself in designing patterns and executing work of an ornamental character.

All ornamental work resolves itself into movements of three kinds--angular, circular and straight. From the combination of these with each other, the times where they merge and emerge, where a movement of one kind changes into any other, where an ellipse becomes part of a circle, where circles are generated across the circumferences of other circles, where these patterns are drawn over and upon each other without destroying the character of either--we say, by such movements, and many others which it would be confusing to follow, the most beautiful forms are made.

Or, if the taste of the workman runs upon mechanical instead of artistic things, there are steam engines to be made, steam boilers to be spun up, of small size; in fact, any piece or machine that can be thought of.

It is almost unnecessary to specify the innumerable kinds of work that can be done in a hand lathe, but the amateur who delights in metal turning may make trinkets of all kinds for his friends, that shall vie in beauty with the best efforts of the jeweler and goldsmith. This, of course, is dependent on the material used, the taste of the workman, and his originality of conception. Pins for ladies' wear can be made of boxwood and ebony, glued together in sections, of all designs, and afterwards turned in beads and mouldings, or otherwise ornamented in a chuck, as will be shown hereafter. Sleeve buttons can be made of ebony and silver, ivory and silver, pearl and gold, or any combination that is desired. Chess and checker men also afford a chance to display skill. And, besides these, special work of any nature is within the capacity of the machine.

There is no family in this country that would not find it economy to have a foot lathe in the house, where the members have mechanical tastes--not necessarily the male members, for ladies use foot lathes, in Europe, with the greatest dexterity. Some of the most beautiful work ever made, was by Miss Holtzapfel, a relative of the celebrated mechanist of the same name. If there are shovels to be mended, the lathe will drill the holes and turn the rivets. If the handle of the saucepan is loose, it will do the same. If scissors or knives want grinding, there is the lathe; if the castors on the sofa break down, there is the lathe; if skates need repairs, either of grinding or of any other kind, there is the lathe. In short, it ought to be as much a part of domestic economy as the sewing machine, for it takes the odd stitches in the mechanical department that save money.

Let not the inexperienced reader, who hears of a lathe for the first time, be frightened at this array of terms, or diverted from the use of it by the recital. In its simple form, as shown in Fig. 1, it is readily understood, and, after a little practice, easily managed by any one, and, after the first few weeks, the amateur will realize the fruits of his application.

At first, it had not even a continuous rotary motion, but the spindle was driven by a belt worked by a spring pole or its equivalent. The belt was rolled round the spindle, and the pole allowed to spring up; the spindle then revolved the length of the belt, or rope, for belts were not thought of, and the operation was repeated, the work being done only when the force of the spring pole revolved the spindle and the job the right way.

Foot lathes had, prior to the introduction of the engine lathe, been used on very heavy work. It is but a few years, comparatively speaking--not twenty--since cast-iron shafts, six, eight, and ten inches in diameter, were turned in such lathes. For all that we know to the contrary, many jobs, far exceeding this in size, have been thus executed.

In some shops, there are still standing heavy oaken shears, made of timber twenty inches deep, and four or six inches wide, faced with boiler iron, and in the racks above there are long-shanked tools, with which the men of old were wont to do the work.
