A treatise on architecture and building construction . Fig. 58. 9G. The veneering of a small circular column may beaccomplished as shown at Fig. 58. Here a sheet of tin isused, having cleats securely nailed to each end by which hand screws can be madeto press the heated tin cauland veneer tightly to thesurface of the tin should be aboutI inch shorter than thecircumference of the col-umn, in order to leaveroom for the glue that issqueezed out along thejoint. The veneer should be sponged with hot water justbefore straining it around the col-umn. The column and the tinshould be heated before veneer-ing. The advantage of a tin caulis that it requires no waxing, andwill not stretch. A strip of paperwrapped around the core will besufficient to determine the lengthof the veneer, which must beequal to the circumference ofthe column. To bring the twoedges of the veneer togetherwhen the tin caul is removed,long solid cauls are used, asshown at s in Fig. 59. fig. 97. A tapering column is veneered in precisely thesame manner, but to find the length and shape of theveneer, lay out, as in Fig. 60, a b equal to the height of thecolumn and cd equal to the base; continue c e and dc to i;from i as a center, with ic and i c as radii, describe the arcsch and ef\ from <?: as a center, describe the semicircle of thebase c d\ divide the semicircle into any number of equalparts, and mark these parts twice on the unfolded base line 10 JOINERY. 83 cJi\ connect hi\ then cJifc will be the shape and exact
