In using the hand-saw for preparing hardwood for turning, the log is either laid on the common X-form sawing horse or else it is fixed in the jaws of the tail-vice, which latter mode is generally more convenient. In speaking of sharpening the saw, it was shown that the points of saw-teeth, proper for hardwoods, are somewhat less acute than those for deal and ordinary timber.
Figs. 684 and 685 represent the narrow taper saws used for cutting curves and sweeps, especially those required in wide boards. Compared with the generality of saws, these are made thicker on the edge, and arc ground thinner on the back, to allow them more freedom in twisting round curves, the smallest of which require the narrowest blades.
The table-saw, and the compass or lock-saw, fig. 684, which only differ in size, resemble the hand-saws in their general structure and in the forms of their teeth, except that the blades are smaller and narrower, to allow them to lie as a tangent to the curve.
