15. The Turning-saw.
—The turning or bow-saw is used for cutting along curved lines. [Fig. 37] illustrates the manner of holding this saw. The sides of the blade must be held at right angles to the surface of the wood. Either or both handles may be turned, thus turning the blade with reference to the frame. Avoid turning the blade, however, as much as possible and see that the blade is not twisted by turning one handle more than the other.
Fig. 37.
This saw may be used for cutting enclosed curves by boring a hole, releasing one end of the blade and inserting it thru this hole then replacing it in the saw frame.
As the cut of the turning saw is not very smooth, it is advisable to leave about one-sixteenth of an inch between the kerf and the line, to be removed later with the spokeshave.
16. The Compass Saw.
—The compass saw, [Fig. 38], is better suited for inside curve sawing. Its use requires a steady hand, else the thin blade will buckle and break.
