Fig. 389.
The sills, or the lower timbers of the frame which rest upon the foundation, should be got out first, and can be of 4" × 4" stock, and halved at the ends (see Halving) (Fig. 389). Upon these sills is to be set up a 4" × 4" post of the desired length at each corner.[35]
On top of these are placed the plates, which can be of 2" × 4" studding laid flat and halved at the ends. Be sure to get out these pieces before beginning to put them together. Toe-nail the posts to the sills and nail the plates directly down on top of the posts, keeping the latter in a vertical position by temporarily nailing on strips of board diagonally, adjusting these until the posts are vertical and at right angles to the sills (see Plumb and Square).
Next put in vertical studding (2" × 4") at each side of the door-space, and at the sides of the window-spaces, allowing a little more space than the exact widths of the door and window-frames. In the same way horizontal studding should be fitted in above the door-space and above and below the window-spaces, and in any places where it will be a help in stiffening the frame or for nailing on the boarding. Another way is to first fit in pieces of joist horizontally, either midway between the sills and plates (except at the window and door-spaces), or running the entire length above and below the windows. Just where and how many of these pieces are to be put in depends upon the arrangement of the doors and windows, and pieces of vertical studding can be fitted in at each side of the door and window-spaces and wherever advisable. Short braces, with their ends sawed at an angle of 45°, can also be fitted at the corners, where the corner-posts meet the sills and plates, and be nailed in place to help stiffen the frame.
It will be a convenience in working to lay the floor next. For this you will require a number of floor-joists. If the building is only 8' or 10' wide, 2" × 4" studding will do; but if the width is as great as 12', 2" × 6" will be better. These are to be placed on edge on top of the sills, as shown. Place one at each end against the corner-posts (to which it can be nailed), sawing off each end so that it will be flush with the outside of the sill. Distribute these floor-joists so that they will be about 18" apart, and hold them in position by "toeing" a nail through them at each end into the sill beneath, or nailing them to the studding when practicable. Before laying any of these floor-joists trim them off on the under edge, which will rest upon the sills, if necessary to ensure a level surface on top for the floor. Do not neglect this, as such joists frequently vary in width. Now measure the diagonals again, before laying the floor-boards, to be sure that the base of the house is rectangular. If one diagonal is longer than the other, push those corners towards each other until the diagonals are of equal length.
Next lay the floor-boards, lengthways of the building, driving them together tightly by pounding on a waste piece, and nailing them firmly to each floor-joist with two nails. If your floor-boards are not long enough to reach the entire length of the house, you will take pains, of course, to saw them of such a length that the ends of the boards will meet over the middle of one of the floor-joists, arranging the joints so that they will alternate or come at different points of the floor. Saw off neatly all projecting ends of the floor-boards.
You will frequently wish to use more force in driving the floor-boards to a tight joint at the edges than you can easily apply with the hammer. You can easily apply all the pressure required by using two short boards on the principle of the toggle-joint. Arrange these as shown in Fig. 390, one end resting against a temporary cleat or any firm object and the other against the edge of the floor-board. By stepping upon this toggle-joint at its apex, the floor-board will be forced into place. A common way is to pry the board into place with a chisel driven down at the edge.
