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.
A wooden table, secured to the upper edge of the board, H, is
perforated to allow the saw to pass through, and is provided with an
inserted hardwood strip which supports the back of the saw, and which
may be moved forward from time to time and cut off as it becomes worn.
The upper guide of the saw consists of a round piece of hard wood
inserted in a hole bored in the end of the arm, J. The upper end of
the saw is secured in a small steel clamp pivoted in a slot in the end
of a wooden spring secured to the top of the arm, J, and the lower end
of the saw is secured in a similar clamp pivoted to the end of the
wooden spring, K.
