A SIZING CUT
Start the first cut about 2-in, from tailstock end -- then run
it toward the taitstock and off the end of the workpiece,
Next, start another cut 2-in. nearer the headstock -- and
run it also, toward tailstock, to merge with first cut.
Continue in this manner until 2- to4-in, from the headstock
end, then reverse the direction of tool travela nd work one or
two cuts in succession toward the headstock, and off this
end of the workpjece. Never start a cut directly at the end
--if the chisei Catchesthe end, itwill damage the workpiece.
Never take tong cuts while corners remain on the work, as
this tends to tear long slivers from the corners.
The first series of cuts should not be too deep it iS better to
partially reduce the work to a cylinder a(I along its length;
then start a second series of cuts to complete reducing it to
a cylinder. Once cylinder has been formed, step lathe up to
the next faster speed. Further reductions in size ca n now be
carried out by cutting as deeply as desired at any spot along
the work. At this stage, tong cuts, from the center off either
end, can also be taken, Roughing-off generally _scontinued
until the cylinder is approximately 1/8-in larger than the
desired finish size. Roundness can be tested by laying the
gouge on top of the work -- it will not ride up and down
when cylinder is perfectly round_

MAKING SIZING CUTS
Sizing c_Jts are useful to establish approximate finish-size
diameters at various points along a workpiece. The work
can then be turned down to the diameters indicated -- and
be ready for finishing. Diameters for sizing cuts should be
planned to be about 1/8-in. greater than the desired finish
diameters.
A sizing cut is made with the parting tool. Hold the tool in
one hand, and use the other hand to hold an outside caliper
preset to the desired sizing-cut diameter. As the cut nears
completion, lower the chisel point more and more into a
scraping position. When the calipers slip over the workpiece
at the cut, the cut is finished.
SMOOTHING A CYLINDER
The fina! I/8-in. can be removed in two ways. Either use
the I *in. skew, working from center toward both ends and
taking lighter and lighter cuts until finished.
CUTTING A SHOULDER
A shoulder can be the side of a square portion left in the
workpiece, the side of a turned section, or tr}e end of the
workpiece. Most shoulders are perpendicular to work axis;
but a shoulder can be at any angle desired.
