10.5 POSITIONING THE TOOL REST FOR
CIRCUMFERENCE TURNING - FIGS 23 - 26
When turning, the object is to pierce the outer surface of
the wood to a desired depth, then to hold the chisel
steady with the bevel edge parallel to the work
circumference, so that the chisel will peel off a shaving at
this desired depth. The only sure method of holding the
chisel steady is to rest the bevel against the workpiece,
the tool rest will act as a fulcrum to support the chisel
against the downward force of the revolving workpiece
(Fig.23).
If the tool rest is positioned too low, so that the chisel
bevel is held out from the workpiece, (Fig.24) the cutting
edge of the chisel will continue to dig deeper into the
workpiece until the “bite” becomes so deep that you
have difficulty holding the chisel, then the chisel will
begin to bounce or chatter against the workpiece.
If the tool rest is positioned too low, the chisel will be
held extremely high to position the bevel of the chisel
against the workpiece (Fig.25) then the tool rest will lose
its value as a fulcrum and the downward force of the
revolving workpiece will kick the chisel back and possibly
out of your hands.
If the tool rest is positioned too high and the chisel is
correctly positioned for cutting it will strike near the top
of the workpiece where the direction of the force exerted
by the workpiece is almost horizontal and will again
result in kickback (Fig.26).

8.1 WOOD LATHE STAND - FIG. 1
Using the nuts and bolts supplied, fix together both the
top plates
with the four legs
. Bolt on the shelf
or four supports
and tighten all the fixings.
NOTE: The Wood Lathe stand should always be fastened
down securely to the floor using four suitable fixings (not
supplied).
8.2 MOUNTING THE WOOD LATHE TO THE
STAND - FIG. 2
Lift the lathe onto the stands top plates (seek assistance as
this is very heavy). Align the holes in the bed with the
stand and bolt in place using the 8 fixings supplied.
8.3 NO-VOLT ON/OFF SWITCH - FIG. 3
The no-volt switch is recommended to be fixed into place
on the leg of the stand using the two bolts
which are
longer, coming through the rear of the switch box.
NOTE: Make sure the cable from the switch to the motor
will allow the rotation of the headstock. Ensure the lead
never passes between bed and workpiece.
8.4 DRIVE SPUR AND LIVE CENTRE - FIG. 4
Locate the drive spur (with prongs) and the live centre
(with bearing) from the packaging. Insert the live centre
into the barrel of the tail stock and with a piece of
scrap timber and a hammer, tap the spur in until secure.
Carry out the same procedure for the drive spur into the
headstock spindle.
