This forms the drip, from 35 to 31 in the sectionalview in Fig. 130, the balance of the cornice being formed in theusual manner. The face of the modillion is formed as in It is bent as a b c, making them square bends in the brake;the semicircles can be bent over any bar or gas pipe in a viseor elsewhere. Assuming that D is the proper size pipe to corre-spond to e in the sectional view in Fig. 130, the face A, Fig. 132,. Fig. 132. Forming the Modillion Face. 98 Home Instruction for Sheet Metal Workers is placed in the position shown, when A is pressed down in thedirection of the arrow until it looks like B, thus bringing thedouble dots Rx and R1 in A to Rx and R1 in B. The letters andfigures in diagrams D and G are similar to those on pattern forthe face of modillion in Fig. 130. Reverse the face B, Fig. 132,a b in E, being careful to have the double dot R1 against the sideof the proper size pipe G and turn down E, in the position shownby F, bringing 19 to 19v. The balance of the bends are made NOTCHES INDICATE BENC Fig. 133. Method of Obtaining Girth for Iron Base or Lockout. to correspond to the side of the modillion in Fig. 130. The panelmiters are bent and soldered in the cornice; then the modillionsare soldered together, being careful to avoid any twist in them,and also soldered in-their proper position in the cornice. This being done, the iron brace must
