In the engraving accompanying the present article a number of hand
turning tools are shown, also a few tools for the slide rest. These
tools are familiar to machinists and may be well known to many
amateurs; but we give them for the benefit of those who are
unacquainted with them and for the sake of completeness in this series
of articles.
[Illustration: TURNING TOOLS.]
Fig. 1 is the ordinary diamond tool, made from a square bar of steel
ground diagonally so as to give it two similar cutting edges. This
tool is perhaps more generally useful than any of the others. The
manner of using it is shown in Fig. 23; it is placed on the tool rest
and dexterously moved on the rest as a pivot, causing the point to
travel in a circular path along the metal in the lathe. Of course only
a small distance is traveled over before the tool is moved along on
the rest. After a little experience it will be found that by
exercising care a good job in plain turning may be done with the tool.
Fig. 2 shows a sharp V shaped tool which will be found useful for many
purposes. Fig. 3 is a V shaped tool for finishing screw threads. Figs.
4 and 5 are round-nosed tools for concave surfaces; Fig. 6, a square
tool for turning convex and plane surfaces. The tool shown in Fig. 7
should be made right and left; it is useful in turning brass, ivory,
hard wood, etc.
