FRAMING

This is a subject on which volumes have been written. The general

arrangement with the names and sizes of the various members is shown in

the drawing, a design for a small cottage, or bungalow. (Fig. 227.)

The heavy timbers forming the sill are cut to the outside dimensions

of foundation and halved at the corners. Fasten the joints with ten

or twelve penny nails. Cut all corner posts exactly the same length,

toenail at corners to sill, and hold in position by temporary braces.

Plumb the posts as the braces are nailed. Two boys must work at this

job, one holding the plumb and the other nailing the braces. Cut and

halve the ends of plate the same length as sill, and nail to corner

posts. Cut 2 × 4 studs same length as posts, then nail to sill and

plate 16 inches apart on centres. The openings to be left for doors and

windows will break up the even spacing of the studs, but it should be

made as uniform as possible. The spaces for door and window frames are

to be enclosed with double studs to give the necessary strength. Corner

braces are very desirable and in the old-fashioned braced frame were

mortised into plate and post, and sill and post. (Fig. 227_a_.)

For a simple structure the necessary bracing may be obtained by

"letting into" the studding 3 × 1 inch strips, as shown in drawing. To

do this hold the brace in the position it is to occupy, and make a

pencil mark on both sides of it on each timber, sawing on the inside

of these lines to a depth equal to thickness of brace. Remove the wood

between saw cuts with a chisel. Test to see that brace comes flush with

outside of studs, and nail securely in position.

When the frame is finished up to the roof the putting on of the siding

may begin at any time.
