Book excerpt: THIS little runabout, named Pop-Gun by one who saw a model of her, is a 20-footer of such simple con- struction that anyone can undertake her construc- tion with certainty of success - that is, anyone who knows enough of the use of tools to build a box. All that is needed is a knowledge of how to use a saw, how to plane the edge of a board straight, and how to nail lumber to- gether. There are very few curved cuts to be made, and nearly every cut is along a straight line that may be snapped with a chalk-line or drawn with a straight edge. In fact, the designing of a boat like this is the hardest part, and that is done. Simplicity in every feature has, of course, been the leading object in designing Pop-Gun, but simplicity is quite possible in a very good little runabout, and Pop- Gun will prove a handy, serviceable, sturdy boat that will carry several people easily, and travel along at about eight miles an hour with a 3-hp. mot6r. The construction of a round-bottomed boat requires considerable skill other than that necessary to use the tools. The shaping of each frame and plank is quite an art; but in this boat the construction is so simple that anyone should succeed in producing a good boat. We will take each piece of wood in turn and tell you just how to shape it. First come the three patterns, or molds, that give you the desired shape. These are shown clearly and with all the necessary dimensions marked on them for repro- ducing them full size. A large sheet of brown wrapping paper will do if a clean board floor is not available to draw them on. Take the shape of the middle mold, No. 2, for exam- ple. Draw a straight line horizontally across the paper or floor and with a large, steel carpenter's square draw a center line, which we show here dotted at right angles to it. Each side of this center line measure off 2 feet 4> DEGREES inches, which represents the width of the boat at the deck to the inside of the planking. Eighteen and one- quarter inches below this - the distance given in the plans of the molds - draw another horizontal line and measure f out two feet each side DEGREES- that distance, i8j4 inches, repre- sents the vertical depth of the side plank, which of course, if measured on the angle will be a fraction longer; 19 ]finches it really is. Four and three-quarter inches below the second line draw another short one representing the keel and measure out three inches each side, the keel being six inches wide. By drawing lines connecting these spots you have the outline of the mold. The- others are found in exactly the same way, using the distances marked on the plans. Wooden patterns have to be made of these three molds so that when properly spaced and set up the planks forming the boat can be bent around them. This causes quite a little strain to come on the molds, so do not build them so flimsily that they will give or break under the strain, and cause your boat to be built crooked. in Figure I I have .shown one method of putting to- gether a mold, and in Figures 2 and 3 other ways are shown. It matters little which way you build them: the
