6. Intended Use of the Lathe
If using a skew chisel, the cutting edge should be applied
approximately 3/8" (10 mm) above the centre height, see
fig 6.7. A spindle gouge's cutting edge should come into
contact with the workpiece approximately 3/8" (10 mm)
below its centre, see fig 6.8.
Using the Roughing Gouge
The first step when turning between centres is invariably
to 'rough out' the blank. This involves taking a square
section blank and paring it down with a roughing gouge
to a cylindrical profile, ready to shape into the final piece.
Roughing gouges are usually sharpened to have the bevel
at a 45º angle. Using the tool rest to support the blade,
offer the blade to the workpiece at an angle, see fig 6.9.
When offering the roughing gouge to the workpiece, the
bevel should be rubbing it, without cutting. To make a
cut, gently raise the handle of the tool in order to bring
the cutting edge into contact with the timber. Using light
passes, move the blade outwards towards the same edge
of the timber which the blade is facing, fig 6.9. Never
move the tool backwards, as this introduces the risk of
splintering the wood and causing injury.
Using the Spindle Gouge
A spindle gouge is used to shape the final profile of a
spindle and is capable of finer work than a roughing
gouge. It is designed specifically for cutting coves or
valleys. The blade should come into contact with the
wood at just below the centre line. Resting it on the tool
rest, apply the blade to the workpiece at an angle, see
fig 6.10, rubbing the bevel onto it. Raise the handle
to apply the cutting edge and make cuts. As with the
roughing gouge, use controlled and light passes, trying
to not remove too much wood at once. Never attempt to
use a spindle gouge for working on bowls or hollow form
work as the angle of the cutting bevel of the gouge is
too shallow and will cause it dig in to the work piece or
snatch the tools from your hands.
