Fig. 234a.
In Fig. 234a the roof has no gutter, so that the end of the rafter is cut off at an angle and a molding applied on the face-board. The base is nailed to the rafters. This is the cheapest and simplest form of structure for the roof.
Setting Door and Window Frames.—The next step in order is to set the door and window frames preparatory to applying the weather boarding. It is then ready for the roof, which should be put on before the floor is laid.
Plastering and Inside Finish.—Next in order is the plastering, then the base-boards and the casing; and, finally, the door and windows should be fitted into position.
Enough has been said here merely to give a general outline, with some details, how to proceed with the work.
CHAPTER XII
BRIDGES, TRUSSED WORK AND LIKE STRUCTURES
Bridges.—Bridge building is not, strictly, a part of the carpenter's education at the present day, because most structures of this kind are now built of steel; but there are certain principles involved in bridge construction which the carpenter should master.
Self-supporting Roofs.—In putting up, for instance, self-supporting roofs, or ceilings with wide spans, and steeples or towers, the bridge principle of trussed members should be understood.
