models where the
base is to be left straight. It will also be found to save much stock
when working with expensive woods.
LATHE ADJUSTMENTS
To get the best results in face-plate or chuck turning there should be
no end play in the spindle of the lathe. The spindle should always be
tested out, and if any play is found, should be adjusted before
attempting any work. It is almost impossible to make a true cut when
such a condition obtains.
POSITION OF TOOL REST
For all face-plate and chuck turning the tool rest should be kept as
close to the stock as possible, the same as in spindle turning,
regardless of the angle it may be set. Vertically, the rest in most
cases should be sufficiently below the center of the stock to bring the
center or cutting point of the tools used, when held parallel to the bed
of the lathe, even with the center of the stock. This last condition
will necessitate adjusting the height occasionally when changing from
large to small tools.

TOOL PROCESSES IN FACE-PLATE AND CHUCK TURNING
B-I--1-a. Straight Cuts
1. ROUGHING OFF CORNERS. (3/4" GOUGE.) FIG. 14. The tool rest is set
crosswise to the bed of the lathe and parallel to the face of the stock.
Place the gouge on the rest with the handle well down. Roll the gouge to
the left until the grind which forms the cutting edge is perpendicular
to the stock. The point of contact should be slightly below the center
or nose of the tool.
The handle of the gouge is then swung well to the back of the lathe or
to the operator's right. The gouge is then pushed forward into the stock
and to the left, making a shearing cut. The cut should not be too heavy.
The starting point for this cut should be a line which will indicate the
largest diameter or circle that can be made from the block.--This cut
should be repeated until the corners are removed from the block.
To complete the cutting of thick stock it will be found necessary to
change the tool rest to an angle of 45 deg. with the bed of the lathe.
[Illustration: Fig. 14.]
When hardwood is being turned it is sometimes advisable to saw the block
almost round with a compass saw or bandsaw, if one is to be had. Should
this be done the preceding steps are omitted.
The tool rest is then placed parallel with the lathe bed and a roughing
cut is taken with the gouge the entire thickness of the block.
The lathe should be run on second or third speed until the corners are
