How Any Structure Is Built Up
: How Work is Laid OutIt should be observed that each structure, however small, is usually built from the base up. Just the same as the more pretentious buildings are erected: First, the sill, then the floor supports, then the posts and top plates, with their connecting girders, and, finally, the roof.
The chapter on House Building will give more detailed illustrations of large structures, and how they are framed and braced. At this point we are more concerned in knowing how to proceed in order to lay out the simple structural details, and if one subject of this kind is fully mastered the complicated character of the article will not be difficult to master.

Forcing Saws In Wood
One of the reasons why the forcing of saws is such a bad practice will be observed in cutting white or yellow pine. For cross-cutting, the saw should have fine teeth, not heavily set, and evenly filed. To do a good job of cross-cutting, the saw must... Forming Lines And Shadows
It is not my intention to furnish a complete treatise on this subject, but to do two things, one of which will be to show, among other features, how simple lines form objects; how shading becomes an effective aid; how proportions are formed; and, ... Framework
As we now know the sizes, the first thing is to build the framework. The legs should be dressed square and smoothed down with the fore plane to make them perfectly straight. Now, lay out two mortises at the upper end of each leg. Follow the illust... Front And Side Lines
From the floor diagram, and the door and window spaces, as marked out, we may now proceed to lay out rough front and side outlines of the building. The ceilings are to be 9 feet, and if we put a rather low-pitched roof on the square structure (Fig. ... Fundamental Truss Form
In every form of truss, whether for building or for bridge work, the principles of the famous A-truss must be employed in some form or other; and the boy who is experimentally inclined will readily evolve means to determine what degree of strength t... Fundamentals Of Designing
A great deal of the pleasure in making articles consists in creative work. This means, not that you shall design some entirely new article, but that its general form, or arrangement of parts, shall have some new or striking feature. A new design in... Gages
One of the most valuable tools in the whole set is the gage, but it is, in fact, the least known. This is simply a straight bar, with a sharpened point projecting out on one side near its end, and having an adjustable sliding head or cheekpiece. Thi... General House Building
We are to treat, generally, on the subject of house building, how the work is laid out, and how built, and in doing so I shall take a concrete example of the work. This can be made more effectual for the purpose if it is on simple lines. ... General Observations
If the workman will carefully observe the foregoing requirements he will have taken the most important steps in the knowledge of the art. If he permits himself to commence work without having his tools in first-class condition, he is trying to do wo... Good Taste In Staining
Oak, mahogany, cherry, black walnut, and like imitations are always good in an artistic sense, but imitations of unfamiliar woods mean nothing to the average person. The too common mistake is to try to imitate oak by staining pine or poplar or birch... Great Contrasts Bad
Violent contrasts in furniture staining have the effect of cheapness, unless the contrasting outlines are artistically distributed throughout the article, from base to top finish. ... Hard Wood Imitations
It would be better to use, for instance, ash or oak for one portion of the work, and a dark wood, like cherry or walnut, for the other part; but usually a cherry cabinet should be made of cherry throughout; while a curly maple chiffonier could not b... Hard Woods
Of the hard woods, cherry is the most desirable for the carpenter's tool. For working purposes it has all the advantages of a soft wood, and none of its disadvantages. It is not apt to warp, like poplar or birch, and its shrinking unit is less than ... Harmonizing Wood
Imagine a chiffonier with the base of dark wood, like walnut, and the top of pine or maple, or a like light-colored wood. On the other hand, both walnut and maple, for instance, may be used in the same article, if they are interspersed throughout th... Harmony Of Parts
But one thing should be observed in the making of furniture, namely, harmony between the parts. For instance, a table with thin legs and a thick top gives the appearance of a top-heavy structure; or the wrong use of two different styles is bad fro... Heavy Lines
But there is an exception to this rule. See two examples (Fig. 140). Here two parallel lines appear close together to form the edge nearest the eye. In such cases the second, or upper, line is heaviest. On vertical lines, as in Fig. 141, the secon... Holding The Gage
The hand serves to keep the cheekpiece against the board, while the thumb pushes the gage forward. The hand must not, under any circumstances, be used to move the gage along. In fact, it is not necessary for the fingers to be clasped around the gage... How Any Structure Is Built Up
It should be observed that each structure, however small, is usually built from the base up. Just the same as the more pretentious buildings are erected: First, the sill, then the floor supports, then the posts and top plates, with their connecting ... How To Characterize Surface
Suppose we commence simply with straight lines. How shall we determine the character of the surface of the material between the two straight lines shown in Fig. 125? Is it flat, rounded, or concaved? Let us see how we may treat the surface by simp... How To Set
To set a saw accurately, that is, to drive out each tooth the same distance, is the first requirement, and the second is to bend out the whole tooth, and not the point only. In the illustration (Fig. 10), the point is merely bent out. This is wrong.... How To Start A Saw
If the untried apprentice has such an opinion set him to work at the task of cutting off a board accurately on a line. He will generally make a failure of the attempt to start the saw true to the line, to say nothing of following the line so the ker... How To Start On A Line
The first mistake he makes is to saw <em>on the line</em>. This should never be done. The work should be so laid out that the saw kerf is on the discarded side of the material. The saw should cut alongside the line, and <em>the line should not</em> ... Illustrating Cube Shading
In Fig. 137 I show merely nine lines joined together, all lines being of equal thickness. As thus drawn it may represent, for instance, a cube, or it may show simply a square base (A) with two sides (B, B) of equal dimensions. ... In The Use Of Grindstones
There are certain things to avoid and to observe in the use of stones. Never use one spot on the stone, however narrow the tool may be. Always move the tool from side to side. Never grind a set of narrow tools successively. If you have chisels to gr... Incorrect Way To Hold Tool For Grinding
The incorrect way of holding a tool is shown in Fig. 18. This, I presume, is the universal way in which the novice takes the tool. It is wrong for the reason that the thumbs of both hands are on top of the blade, and they serve as pivots on which t... Intermediate Studding
It will then be an easy matter to put in the intermediate 2" × 4" studding, placing them as nearly as possible 16 inches apart to accommodate the 48-inch plastering lath. <div> <img src="/images/fig232.jpg" alt="Fig. 232." title=""... Irregular Curves
But the irregular curves require the most care to form properly. Let us try first the elliptical curve (Fig. 148). The proper thing is, first, to draw a line (A), which is called the "major axis." On this axis we mark for our guidance tw... Isometric Cube
I enclose this cube within a circle, as in Fig. 143. To form this cube the circle (A) is drawn and bisected with a vertical line (B). This forms the starting point for stepping off the six points (C) in the circle, using the dividers without resetti... Joints
For joining together boards at right angles to each other, such as box corners, drawers and like articles, tenons and mortises should never be resorted to. In order to make fine work the joints should be made by means of dovetails, rabbets or reba... Knowledge Of Tools
A knowledge of tools and their uses is the first and most important requirement. The saw, the plane, the hatchet and the hammer are well known to all boys; but how to use them, and where to use the different varieties of each kind of tool, must be l... Lap-and-butt Joint
The lap-and-butt is the form of uniting members which is most generally used to splice together timbers, where they join each other end to end. <div> <img src="/images/fig210.jpg" alt="Fig. 210." title="" height="140" width="400" /> Fig. 210. </div> ... Laying Out The Legs
Fig. 27 shows a leg with square cross marks (A) at each end. These marks indicate the finished length of the leg. You will also see crosses on two sides. These indicate what is called the "work sides." The work sides are selected because they are th... Learning Mechanical Forms
Suppose, for example, we take the words <em>segment</em> and <em>sector</em>. Without a thorough understanding in your own mind you are likely to confuse these terms by taking one for the other. But let us assume you are to be called upon to expla... Lessons From The Doric Column
As an example, suppose we take a plain cabinet, and endeavor to embellish it with the types of molding described, and you will see to what elaboration the operation may be carried. ...
