If necessary to use screws where the heads willshow, first make, if possible, with bit or chisel a neat round or square holeof sufficient diameter to admit the head of the screw and deep enough toallow a plug of the same kind of wood to be inserted after the screw hasbeen driven (see page 189). 144. Glue and Its Use.—Glue is made from refuse animal matteror from parts of fish. It comes in sheets or cakes or flakes or ground,to be dissolved and used hot, or in liquid form to be used cold. Hotglue is preferable for nice work if all conditions are as they should be,otherwise, cold glue may be better. In either case, buy the best. Fig. 510 i82 A Shorter Course in Woodworking grade. Do not use glue that has a mouldy or otherwise disagreeablesmell. The only sure test is to get a little and try it. Glue end-wood underpressure after sizing (see page 184), leave until hard, and see how muchforce is required to break the joint. Soak glue over night, or as long as maybe necessary, in as much water as you think it will absorb. The more itwill swell without dissolving, the better the quality. You cannot tell goodglue by the color, for there are many kinds and many makers; but it shouldbe clear looking. The Glue-pot is made of copper, iron, or tin, and is like the doubleboiler used in kitchens to prevent overheating. It should have acover. Glue-brush.—Brushes are made especially for glue. A good one canbe made of a stick of rattan. Soften the end in hot water and poundit with the hammer until the fibres separate. For corners, cracks, andholes, use
