Woodworking for beginners; a manual for amateurs . e pin. An eight-sided one is just as good. Do not use too large pins. In sliii)-building, bridge-building,and old-fashioned house-framing pins and treenails from ito 11 or more in diameter, are used. Dowels of various sizeswill usually answer for such framing as you may have to do(though a rift-pin is stronger). For such work as pinning a jointin a chair, you will not need anything larger than a ^ hardwoodpin. You must use judgment as to how near the edge to place thepin. If you put it too far from the edge, its hold on the tenonwill be weak and the end of the tenon may break out (shear).If you put it too near the edge, the sides of the mortise may tearor split out. ? Sometimes, particularly in timber work, to insure a snug fit atthe joint, draw-boring is resorted to (Fig. 594). The hole forthe pin is not bored through the tenon as just shown, but is boreda trifle nearer the shoulder of the tenon than the other holes(in the mortise-piece). The result is that when the pin is driven.
