Shadows From A Solid Body
: DRAWING AND ITS UTILITYWe can understand this better by examining Fig. 129, which shows a vertical board, and a beam of light (A) passing downwardly beyond the upper margin of the board. Under these conditions the upper margin of the board appears darker to the vision, by contrast, than the lower part. It should also be understood that, in general, the nearer the object the lighter it is, so that as the upper edge of the board is farthest from the eye the heavy shading there will at least give the appearance of distance to that edge.
But suppose that instead of having the surface of the board flat, it should be concaved, as in Fig. 130, it is obvious that the hollow, or the concaved, portion of the board must intensify the shadows or the darkness at the upper edge. This explains why the heavy shading in Fig. 126 is at that upper margin.

Planes
The plane may be called the æsthetic tool in the carpenter's kit. It is the most difficult tool to handle and the most satisfactory when thoroughly mastered. How to care for and handle it will be referred to in a subsequent chapter. We are n... Plastering And Inside Finish
Next in order is the plastering, then the base-boards and the casing; and, finally, the door and windows should be fitted into position. Enough has been said here merely to give a general outline, with some details, how to proceed with the work. ... Polishing Stained Surfaces
If, on the other hand, you wish to go to the labor of polishing the furniture to a high degree, staining becomes an art, and will add to the beauty and durability of any soft or cheap wood, excepting poplar. When the article is highly polished, so a... Preparing A Box Joint
In order to match a box joint for the inner end of a table drawer, the first step is to select two work sides. One work side will be the edge of the board, and the other the side surface of the board, and on those surfaces we will put crosses, as he... Proper Designations
Every part in mechanism, every point, curve and angle has its peculiar designation. A knowledge of terms is an indication of thoroughness in education, and, as heretofore stated, becomes really the basis of art, as well as of the sciences. When you ... Proper Terms
It is the application of the correct terms to things that lays the foundation for accurate thinking and proper expressions in describing work. A wise man once said that the basis of true science consists in correct definitions. ... Proportional Dividers
A useful tool is called the proportional dividers, the legs of which are hinged together intermediate the ends, so that the pivotal joint is adjustable. By means of this tool the scale of work may be changed, although its widest field of usefulness ... Representing Objects
But let him try to represent some object, and the pens become useless. There is a vast difference in the use of drawing tools and free-hand drawing. While the boy who is able to execute free-hand sketches may become the better artist, still that art... Room Measurements
We must now determine the dimensions of each room, and then how we shall build the roof. In Figs. 223 and 224, we have now drawn out in detail the sizes, the locations of the door and windows, the chimneys and the closets, as well as the bathroom... Rule For Mortises
Fig. 206 shows such an example. You will notice this in doors particularly, as an example of work. <div> <img src="/images/fig206.jpg" alt="Fig. 206." title="" height="89" width="156" /> Fig. 206. </div> <div> <img src="/images/fig207.jpg" alt="Fig. ... Saw Clamps
These are necessary adjuncts, and should be made of hard wood, perfectly straight and just wide enough to take in the narrow back saw. The illustration shows their shape and form. ... Saw Clamps
You may easily make a pair of saw clamps as follows: Take two pieces of hard wood, each three inches wide, seven-eighths of an inch thick, and equal in length to the longest saw. Bevel one edge of each as shown in A (Fig. 15), so as to leave an edg... Scarfing
This method of securing members together is the most rigid, and when properly performed makes the joint the strongest part of the timber. Each member (A, Fig. 212) has a step diagonally cut (B), the two steps being on different planes, so they form ... Sector And Segment
Now examine the shape of the body formed by two of the radial lines (E, E) and that part of the circle which extends from one radial line to the other. The body thus formed is a sector, and it is made by two radiating lines and a curved line. Learn ... Self-supporting Roofs
In putting up, for instance, self-supporting roofs, or ceilings with wide spans, and steeples or towers, the bridge principle of trussed members should be understood. The most simple bridge or trussed form is the well-known A-shaped arch. <div> <im... Setting Door And Window Frames
The next step in order is to set the door and window frames preparatory to applying the weather boarding. It is then ready for the roof, which should be put on before the floor is laid. ... Setting Up

Now, to examine it properly so as to observe what the draughtsman wishes to express, look at Fig. 138, in which the three diverging lines (A, B, C) are increased in thickness, and the cube appears plainly. On the other hand, in Fig. 139, the thicken... Shading With Beads And Rabbets
You will see from the foregoing, that these embellishments are serviceable because they provide the article with a large number of angles and surfaces to cast lights and shadows; and for this reason the boy should strive to produce the effects which... Shadows From A Solid Body

A very simple turning lathe may be made by following these instructions: ... Soft Wood
As, presumably, most of your first work will be done with pine, poplar, or other light-colored material, and, as many people prefer the furniture to be dark in color, you should be prepared to accommodate them. ... Soft Woods
It is also well for the novice to do his initial work with a soft wood, because in joining the parts together inaccuracies may be easily corrected. If, for instance, in mortising and tenoning, the edge of the mortised member is not true, or, rather,... Spirals
There is no more difficult figure to make with a bow or a circle pen than a spiral. In Fig. 150 a horizontal and a vertical line (A, B), respectively, are drawn, and at their intersection a small circle (C) is formed. This now provides for four cent... Staining Contrasting Woods
Then, again, do not stain a piece of furniture so that one part represents a cheap, soft wood, and the other part a dark or costly wood. Imagine, for instance, a cabinet with the stiles, rails and mullions of mahogany, and the panels of pine or popl... Stains As Imitations
It will be well to remember one thing as to stains. Never attempt to stain anything unless that stain is intended to produce an imitation of some real wood. There are stains made up which, when applied, do not imitate any known wood. This is bad t... Steps In Cutting Mortises
Examine Fig. 208, which, for convenience, gives six successive steps in making the mortise. The marks <em>a</em>, <em>b</em> designate the limits, or the length, of the mortise. The chisel (C) is not started at the marking line (A), but at least an ... Straight-faced Moldings

Fig. 190 is also called the <em>scape</em>, and is a concaved type of molding, being a hollowed curvature used on columns where its form causes a merging of the shaft with the fillet. <div> <table summary="Fig 189/192" border="0" cellpadding="0" ... The Astragal
Fig. 186 shows the ankle-bone molding, technically called the <em>Astragal</em>. This form is round, and properly placed produces a good effect, as it throws the darkest shadow of any form of molding. <div> <table summary="Fig 187/188" border="0"... The Basis Of Moldings
Suppose we take the base type of moldings, and see how simple they are and then, by using these forms, try to build up or ornament some article of furniture, as an example of their utility. ... The Bead And Rabbet
