Greenhouses. THE WOODWOEK. 57 These angles can be obtained either from the working plan, if on a sufficiently large scale, or a first pair of rafters may be cut and fitted to the plates and ridge exactly, and the mitre-box be made from these. When nailing in the bars a guage should be used to keep them at the exact distance apart to take the glass easily, yet without too much play. A bit of plain lath or bead will do, and it should be i''"- *2. cut to a bare l-16th of an inch longer than the exact width of the glass. This will allow of the latter going in just right, if each bar is pushed up tight to the gauge top and bottom. Only those who have tried it can know the trouble and nuisance it is to put in glass with bars -J-in. to |in. too far apart, and when done it is almost sure to leak badly. The bradawl must be used in both ends of the bars before nailing, otherwise they will probably split, the smaller sizes in particular. The end-rafters, which are usually made a little stouter than the rest, are worked to the section shown at Fig. 42. Next, the construction of the eaves, and the manner in which the drip-water is carried into the gutter, needs some amount of consideration. Of course, where framed lights or sashes are used, the lower edge of the bottom rail is projected 2in. or Sin. beyond the plate, and from it the water drips directly into the gutter ; but where only glass and bars are employed an arrangement of some kind is necessary. The lower edge. Fig. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations m
