Now will he observed that tlic material is cut outsquare to the face of the plank. The bevelsare applied, as shown, to both ends; in thiscase reversely; that is, at the end a towardthe inside and at the end c toward the out-side of the wreath. Tn Fig. 68 is shown the wreath after it istwisted and the bevels applied. To lay out the face mold for the quarterturn placed between the second and thirdflights of stairs as indicated in the plan view>Fig. 65, place one leg of the compasses in Fig. Fig. 67. Fig. 67.—View of the Plank from Which t;;e Wreath Is Cut Square to Its Surface and the Bevels Applied at Each End, Showing How the Wreath Is Twisted. Fig. 68.—View of Wreath After It is Twisted and the Bevels Applied. fix the string to the pins, as shown, and withthe pencil on the minor axis draw the curves,as shown, from the end a of the mold to theend c. Make the joints at each end squareto the tangents, thus completing the formof the face mold. The width of the mold at each end wastaken from the bevels shown in diagram order to find the bevels made a n of thediagram the same length as a w of the n m the same length as the line iv m,shown in the elevation; connect m with aand the angle at m will be the bevel to applyto the end c of the mold. Make n c of diagram D equal in length tothe line c t of the elevation and connect cwith a. Then the angle at c will be thebevel to apply to the end a of the face mold,where the wreath connects to the newel
