[Illustration: Assembled Lathe Bed and Bearing Details]

The bed of the machine is made of wood as shown in Figs. 2 and 3,
hardwood being preferable for this purpose. Fig. 2 shows an end
view of the assembled bed, and Fig. 3 shows how the ends are cut
out to receive the side pieces.

The headstock, Fig. 6, is fastened to the bed by means of carriage
bolts, A, which pass through a piece of wood, B, on the under side
of the bed. The shaft is made of 3/4-in. steel tubing about 1/8
in. thick, and runs in babbitt bearings, one of which is shown in
Fig. 5.

To make these bearings, cut a square hole in the wood as shown,
making half of the square in each half of the bearing. Separate
the two halves of the bearing slightly by placing a piece of
cardboard on each side, just touching the shaft. The edges which
touch the shaft should be notched like the teeth of a saw, so as
to allow the babbitt to run into the lower half of the bearing.
The notches for this purpose may be about 1/8 in. pitch and 1/8
in. deep. Place pieces of wood against the ends of the bearing as
shown at A and B, Fig. 4, and drill a hole in the top of the
bearing as shown in Fig. 4.

The bearing is then ready to be poured. Heat the babbitt well, but
not hot enough to burn it, and it is well to have the shaft hot,
too, so that the babbitt will not be chilled when it strikes the
shaft. If the shaft is thoroughly chalked or smoked the babbitt
will not stick to it. After pouring, remove the shaft and split
the bearing with a round, tapered wooden pin. If the bearing has
been properly made, it will split along the line of the notched
cardboard where the section of the metal is smallest. Then drill a
hole in the top as shown at A, Fig. 5, drilling just deep enough
to have the point of the drill appear at the lower side. This
cavity acts as an oil cup and prevents the bearing from running
dry.

The bolts B (Fig. 5) are passed through holes in the wood and
screwed into nuts C, which are let into holes

This type of bearing will be found very satisfactory and may be
used to advantage on other machines. After the bearings are
completed the cone pulley can be placed on the shaft. To make this
pulley cut three circular pieces of wood to the dimensions given
in Fig. 6 and fasten these together with nails and glue. If not
perfectly true, they may be turned up aft
