A treatise on architecture and building construction . wo cauls a, a sufficing to securethe whole. 94. Thin veneers are often found in a badly crumpledcondition. In this case, they must be sponged with hotwater and squeezed gradually and evenly with hand screwsbetween plane-surfaced cauls, and left several hours orover night, until they are in a fit condition to be heavy weights placed on a caul over themoistened veneers are sufficient to accomplish the sameeffect. 95. To join two pieces of thin veneer together, theymust be cut with a sharp knife, guided by a perfect straight-edge. The pieces are laid upon a plane surface with paperunderneath, and are tacked at a convenient distance on eachside of the joint in such a way as t(j draw tlie two piecestogether; then a strip of strong Manila paper is ghicd overthe joint, and the veneer is placed on a suitable straiglitstrip of wood tmder heavy pressure and allowed to remainuntil the glue is dry. In laying this jointed veneer, thepapered side must be laid outwards. 82 JOINERY. 10. 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. 59.
