ecting
from the center of the bar, D, supports an arbor having at one end a
socket for receiving the twisted iron bar, E, and at the other end a
center and a short finger or pin. A metal disk having three spurs, a
central aperture, and a series of holes equally distant from the
center and from each other, is attached by its spurs to the end of the
cylinder to be fluted, and the center of the arbor in the arm, D,
enters the central hole in the disk while its finger enters one of the
other holes. The opposite end of the cylinder is supported by a center
screw. A fork attached to the back of the table embraces the twisted
iron, E, so that as the wooden cylinder is moved diagonally over the
cutter it is slowly rotated, making a spiral cut. After the first cut
is made the finger of the arbor is removed from the disk and placed in
an adjoining hole, when the second cut is made, and so on.

Figs. 6 and 7 show a convenient and easily made attachment for
moulding the edges of irregular work, such as brackets, frames, parts
of patterns, etc. It consists of a brass frame, F, supporting a small
mandrel turning at the top in a conical bearing in the frame, and at
the bottom upon a conical screw. A very small grooved pulley is
fastened to the mandrel and surrounded by a rubber ring which bears
against the face plate of the lathe, as shown in the engraving. The
frame, F, is let into a wooden table supported by an iron rod which is
received by the tool rest holder of the lathe. The cutter, G, is made
by turning upon a piece of steel the reverse of the required moulding,
and slotting it transversely to form cutting edges. The shank of the
cutter is fitted to a hole in the mandrel and secured in place by a
small set screw. The edge of the work is permitted to bear against the
shank of the cutter. Should the face plate of the lathe be too small
to give the required speed, a wooden disk may be attached to it by
means of screws and turned off.

Figs. 8, 9, and 10 represent a cheaply and easily made scroll saw
attachment for the foot lathe. It is made entirely of wood and is
practically noiseless. The board, H, supports two uprights, I, between
which is pivoted the arm, J, whose under side is parallel with the
edge of the board. A block is placed between the uprights, I, to limit
the downward movement of the arm, and the arm is clamped by a bolt
which passes through it and through the two uprights and is provided
with a wing nut.
