Now turn the boat bottom side up and nail the bottom on, as already described in previous chapters (Fig. 232). The bottom-boards are to be so planed upon their edges that they leave V-shaped grooves on the inside of the boat to be calked with candlewick and putty (Fig. 231). Next make a shaft-log by cutting a board in a triangular piece, as shown inFig. 233, and nailing two other pieces of board on it, and leaving a space for the shaft-rod,over which is nailed a duplicate of the bottom-board, as shown inFig. 234. Make the shaft-log of three thicknesses of 1-inch plank. To make it more secure there should be a board nailed on the inside bottom of the boat, as shown inFig. 235by the dotted lines.
This board is put there to strengthen the bottom and allow us to cut a slot through for the admission of a shaft (Fig. 236) which is drawn on a scale shown below it. With the engine comes a stuffing box, through which the shaft passes and which prevents the water from coming up through the shaft-hole. The stuffing boxes, which are furnished to fit upon the inside of the boat, are expensive, but one to fit upon the stern of the shaft-log costs but little, and will answer all purposes.
Of course, when attaching the shaft-log to the bottom, it must be in the exact centre of the boat. Find the centre of the boat at the bow and stern, mark the points and snap a chalk-line between them. Now place the shaft-log in position on this line and while holding that there firmly, mark around it with a carpenter's pencil. Next lay the shaft-log flat on its side with its edge along this line and with your pencil mark on the bottom of the boat the exact place where the shaft-hole must be cut to correspond with the one in the shaft-log. As may be seen byFig. 236, the shaft runs through at an acute angle; hence the hole must be bored on a slant, or better still a slot cut through the floor long enough to allow for the slant.

The leak, which would naturally occur here is prevented by the stuffing box which is fastened on to the stern-end of the shaft-log where the latter protrudes for the propeller. To set the engine in the boat it is necessary to have an engine-bed. This is made of two pieces of board cut diagonally, upon which the engine rests.
Fig. 237shows a piece of 2-inch board and a method of sawing it to make the duplicate pieces to form the engine-bed. The dimension of these pieces must be obtained by measuring the width of the engine rest, which is to be installed. The angle, of course, must correspond to the angle of the shaft.
Make your own rudder of any shape that suits your fancy, square or paddle-shaped, of a piece of galvanized iron or of wood, as shown in the diagram; or you can simply fasten the rudder-stem to the transom (stern-board), as is often done on row-boats and sail-boats. If you desire to make your rudder like the one shown here, use two pieces of galvanized pipes for your rudder-posts, one of which fits loosely inside of the other. Make the rudder-posts of what is known as3/8-inch (which means literally a3/8-inch opening) and for its jacket use a ¾-inch pipe, or any two kinds of pipe, which will allow one to turn loosely inside the other. The smaller pipe can be bent easily by hand to suit your convenience, after it has been thrust through the larger pipe.
First bend the lower end of the small pipe to fit your proposed rudder, then remove the larger pipe and flatten the lower end of the small one by beating it with the hammer. To bore the screw-holes in the flattened end you will use a small tool for drilling metal. One of these drills, which will fit any carpenter's brace, can be procured for the cost of a few cents.
Drill holes through the flattened end of your pipe for the reception of your screws, which are to secure it to the rudder. It is now necessary to fasten a block of 2-inch plank securely to the bottom of the boat upon the inside where the rudder-post is to be set. This block might best be secured on with four bolts. A hole is then bored through the block and the bottom of the boata trifle smaller than the largest piece of pipe; the latter is supposed to have screw threads upon its lower end (Fig. 238) so that it may be screwed into the wood, but before doing so coat the threads with white lead and also the inside of the hole in the block with the same substance.
When the larger pipe is now screwed into the block until its lower end is flushed with the outside bottom of the boat, the white lead will not only make the process easier, but will tend to keep out the moisture and water from the joint.
From the outside thrust the upper end of the small pipe through the hole in the bottom until it protrudes the proper distance above the larger pipe, and with the point of a nail scratch a mark on the surface of the small pipe where it issues from the big one. At this point drill a hole through the small pipe to admit a nail which is to act as a peg to keep the helm from sliding down and jamming in its bearings.
If you choose, a small seat or deck may be inserted in the stern, through which the helm extends and which will help to steady it. The top of the helm, or protruding ends of the small pipe may now be bent over toward the bow, as shown in the diagram, and by holding some hard substance under it, the end may be flattened with a hammer and two holes drilled through the flattened end for the rudder-line, as inFig. 239. These lines work the rudder and extend on each side of the boat through some clothes-lines pulleys, as shown inFig. 239.
If you slice off the ring from a common rubber hose and slip it over the inside pipe before you fasten it in place, it will prevent the water from spurting up through the rudder pipe when the boat is speeding.
Any boat will leak if not carefully built and the simplest kind of a craft carefully put together is as water-tight as the most finished and expensive boat.
For a gasoline tank any good galvanized iron vessel will answer if it holds five gallons or more of gasoline. It can be placed in the bow on a rest made for it. Of course the bottom of the tank mustbe on a level or higher than the carburetor of the engine; the tank is connected by a small copper, or block-tin pipe, which you procure with the engine.
This boat, if built according to plans, should cost ten dollars or less, not counting the cost of the engine. The cost of the latter will vary according to the style of one you use, and whether you get it first or second hand.
A ten-horse power engine drove a boat of this kind at the rate of eighteen miles an hour.
For beginners, this is as far as it is safe to go in boat-building, but thus far any one with a rudimentary knowledge of the use of tools can go, and, if one has followed the book through from chapter to chapter he should be a good boat-builder at
