This section presents a number of modifications and developments of the elementary tool processes and principles set forth in the earlier sections. Students who have successfully accomplished the work of the first half of this book, or its equivalent, are sufficiently grounded in the fundamentals of shop work to be able to exercise considerable judgment not only in the choice of projects to be undertaken, but also in incorporating original ideas and personal tastes in the designs.

The projects of this section are so varied in nature and function, as well as in amount and expense of materials, that there should be no difficulty in appealing to the immediate interest of every member of any class. While the projects do not all present the same mechanical principles, yet they deal with forms of construction which the students should be capable of handling.

Some students will desire to make some of the smaller projects, which give an opportunity for artistic expression. The candlestick, vase and hand mirror are particularly suitable for practice along this line. A study of the references given under these lessons will guide to the proper conception of motive and design. Other students of a more practical turn of mind may be interested in making projects which will be useful about the home or farm; such lessons will, of course, necessitate a little more expense on account of the amount of material used, but when the value of the finished article is considered the making of usable projects is quite economical.

No attempt is made in this section to introduce principles of cabinet construction; however, the simple box type is employed in some of the projects and the fundamental principles of making opposite sides exactly equal and of assembling parts perfectly square should be carefully impressed.

In practical drawing work students should be able to make a simple sketch and to prepare regular three-view drawings of projects to be undertaken in the shop.

Before leaving this section all students should appreciate the value of keeping their tools in good order and should be able to sharpen the edge tools, such as chisels and plane blades, with considerable skill.
