The tool shown in Fig. 12 might properly be called a barrel saw. It is
made by drilling in the end of a steel rod and forming the teeth with
a file. To avoid cracking in tempering a small hole should be drilled
through the side near the bottom of the larger hole. To insure the
free working of the tool it should be turned so that its cutting edge
will be rather thicker than the position behind it. This tool should
be made in various sizes.
Tools for gear cutting and also cutters for wood have not been
mentioned in this paper; as they are proper subjects for separate
treatment.
WOOD WORKING.
It is not the intention of the writer to enter largely into the
subject of wood working, but simply to suggest a few handy attachments
to the foot lathe which will greatly facilitate the operations of the
amateur wood worker, and will be found very useful by almost any one
working in wood. It is not an easy matter to split even thin lumber
into strips of uniform width by means of a handsaw, but by using the
circular saw attachment, shown in Fig. 1, the operation becomes rapid
and easy, and the stuff may be sawed or slit at any desired angle or
bevel. The attachment consists of a saw mandrel of the usual form, and
a wooden table supported by a right angled piece, A, of round iron
fitted to the toolpost and clamped by a wooden cleat, B, which is
secured to the under side of the table, split from the aperture to one
end, and provided with a thumbscrew for drawing the parts together.
