eful articles. Sugar and maple are two hard woods which may be added to the list. Sugar, particularly, is a good-working wood, but maple is more difficult. Spruce, on the other hand, is the strongest and toughest wood, considering its weight, which is but a little more than that of pine. DIFFERENCES IN THE WORKING OF WOODS.--Different woods are not worked with equal facility by all the tools. Oak is an easy wood to handle with a saw, but is, probably, aside from ash, the most difficult wood known to plane. Ash is hard for the saw or the plane. On the other hand, there is no wood so easy to manipulate with the saw or plane as cherry. Pine is easily worked with a plane, but difficult to saw; not on account of hardness, but because it is so soft that the saw is liable to tear it. FORCING SAWS IN WOOD.--One of the reasons why the forcing of saws is such a bad practice will be observed in cutting white or yellow pine. For cross-cutting, the saw should have fine teeth, not heavily set, and evenly filed. To do a good job of cross-cutting, the saw must be held at a greater angle, or should lay down flatter than in ripping, as by so doing the lower side of the board will not break away as much as if the saw should be held more nearly vertical. These general observations are made in the hope that they will serve as a guide to enable you to select your lumber with some degree of intelligence before you commence work. CHAPTER XIV WOOD TURNING ADVANTAGES OF WOOD TURNING.--This is not, strictly, in the carpenter's domain; but a knowledge of its use will be of great service in the trade, and particularly in cabinet making. I urge the ingenious youth to rig up a wood-turning lathe, for the reason that it is a tool easily made and one which may be readily turned by foot, if other power is not available. SIMPLE TURNING LATHE.--A very simple turning lathe may be made by following these instructions: THE RAILS.--Procure two straight 2" x 4" scantling (A), four feet long, and planed on all sides. Bore four 3/8-inch holes at each end, as shown, and 10 inches from one end four more holes. A plan of these holes is shown in B, where the exact spacing is indicated. Then prepare two pieces 2" x 4" scantling (C), planed, 42 inches long, one end of each being chamfered off, as at 2, and provided with four bolt holes. Ten inches down, and on the same side, with the chamfer (2) is a cross gain (3), the same angle as th
