Pieces of plank C are cut in betweenthe^furring pieces, as shown, so as to give a nailing for the boarding,and they are cut to the shape of segments of circles, so as to formcomplete circles around the tower when they have been put in a tower of this shape is to be built, having a number of faces andhips, the curve of the hip rafters will not be the same as the curveshown by a section through one of the faces of the tower. In orderto find the true curve for the hip rafter, the same method is followed. Fig. 249. Section Showing Frame Constructionof Small Tower 189 178 CARPENTRY as was explained for hip rafters in an ogee roof over a bay window,using the principle that any line drawn in the roof surface parallelto the plate is horizontal throughout its length. By this means anynumber of points in the curve of the hip rafter may be obtainedand the curve for the hip may be drawn through them. Thus a pattern for the hip rafter maybe obtained. Church Spire. Fig. 250shows the method of framinga church spire, or other hightapering tower. The base ofthe drum N is square and issupported by the posts A,one at each corner, whichrest on the sills B. The sillsare supported by the rooftrusses of the main roof. Thecorner posts extend the fullheight of the drum and arestrongly braced in all fourfaces, with intermediate ver-tical studding C betweenthem to form the frameworkfor these faces. The spireitself may rest on
