raw diagonals across the end of the stock.
The point of intersection locates the center.
CLAMPING STOCK IN THE LATHE
Take the live center from the spindle and with a wooden mallet drive the
spur deep into the wood. Never drive the wood onto the live center while
in the spindle because serious injury may be done the machine by such
practice. When extremely hard wood is being used, it is a good practice
to make saw cuts along the diagonal lines and bore a hole at the
intersection, thus allowing the spur to enter the wood more freely. Oil
the other end of the wood while holding it in a vertical position, and
give the oil a chance to penetrate into the wood. Then replace the live
center by taking the stock and center and forcing it into the spindle by
a sudden push of the hand. The tail stock is then moved about 1/2" to 1"
from the end of the piece to be turned, having the tail spindle well
back in the tail stock. The tail stock is then clamped to the lathe bed.
Turn the tail stock hand wheel until the wood is held firmly. Work the
cone pulley by hand at the same time, so that the cup or dead center
will be forced deeply into the wood, so deeply that the live center will
not continue to turn. Now turn the dead spindle back until the live
spindle begins to turn freely and clamp the dead spindle fast.

ADJUSTING THE TOOL REST
Horizontally the tool rest should be set about 1/8" from the farthest
projecting corner of the wood and should be readjusted occasionally as
the stock diminishes in size. The vertical height varies slightly
according to the height of the operator. It is even with the center of
the spindle for a short person; 1/8" above for a medium person; and 1/4"
above for a tall person. So long as the stock is in its square form the
tool rest should never be adjusted while the machine is in motion as
there is danger of the rest catching the corners and throwing the stock
from the machine. Also see that everything is clamped tight before
starting the lathe.
POSITION OF THE OPERATOR
The operator stands firmly on the floor back far enough from the lathe
to allow him to pass the tools from right to left in front of his body
without changing the position of the feet. It may be found convenient
to turn slightly, bringing the left side of the body a little closer to
the lathe. In no case, however, should the tools be brought in contact
with the body as the cutting operation from rig
