The cross Y° is then slippedinto the base A3 as far as Z° or abount ]/& in. below the head B3,and a slight tack made to prevent the cross from sliding any far-ther when the base is set down. When the base is set on a level Making a Paneled Cross 153 surface, and the cross is plumb when viewed from both sides orwhen squared, Fig. 208, a tack is made at aL in diagram Y°, inFig. 202. The joints are soldered tight along aL, ax and a?, after. Fig. 209. Paneled Cross. which the panel head R, Fig. 207, is soldered in place, whichcompletes the cross. All joints should be scraped smooth and sandpapered, whenthe cross will appear as in Fig. 209. When fastening the crossto the spire or ridge of a roof the method is similar to thatexplained in fastening the ornamental finial in Fig. 200. CHAPTER XXScale and Detail Drawings for Making a Pediment on a Wash The thirteenth exercise, known as the pediment on a wash,is presented in a 2-in. scale drawing in Fig. 210. If the studentwill turn back to the exercise on the Ornamental Window Cap,he will find that the pattern for a pediment was developed, thelower part of which was mitered with a horizontal molding, andthe roof was on a horizontal plane. In this case the lower partof the pediment miters with a horizontal molding the roof ofwhich is inclined or has what is known as a wash—that is, aninclined plane to shed water, A°, Fig. 210. This allows rainor snow to drip off, while if the
