Fix a stopper of hard wood along part
of the front edge of the base board or
your bench. This is 50mm ( 2 ”) back
from the edge of the base board or
bench. This stopper will be chipped
away with repeated use so make it
easy to replace.

Spindle or Detail gouge. The main
shaping tools of the spindle turner. Used
for detail work, beads, coves, and ogees,
to which the modern round shape is
particularly suited. 5 to 15mm wide.
Spindle Roughing gouge . An essential
tool for between - centre work ( spindle
turning ) . This tool quickly reduces square
timber to the round. Also ideal for long,
shallow curves. Usually 25mm wide.
Skew Chisel. The skew will produce the
finest possible finish when used correctly.
For cleaning end grain, pommels, rolling
beads, etc. when both long point and heel
can be used. 15 - 50mm wide.
Diamond parting tool. An excellent all
round parting tool. The double taper
provides clearance along the sides of the
tool to prevent excess binding while
cutting.

3. Hold the Tru - rind Tool Holder comfortably in your
hands. Locate the ball foot of the Tool Holder in the
Pivot Point. Apply the chisel to the grinding wheel and
rotate it from side to side. Recheck your angle. Now
continue to grind until you have a sharp edge. With
this system you may grind all of the gouge at one time
or you may grind the sides or the nose or whatever
area you need to. When reshaping a badly ground
gouge, work on the sides only, until they are correct,
and then blend the nose to match.
4. It is important that the pivot leg angle is the same
every time. So once you have decided on which angle
to use, then create a mark to record this angle.
5. If a long - fluted gouge is slim or won ’ t align true in
the Toolholder then insert the Short Steel Rod
supplied under the clamp block “ V ” and into the flute
of the gouge. Tighten as normal.

This style of gouge has the sides of the tip
ground back. To achieve this you need to
adjust the pivot leg on the Toolholder
forward to between positions #4 and #8.
The higher the number, the more the wings
or sides will be ground back. Take note of
the number setting you have chosen. This
can be written on the wooden handle of the
gouge to help you repeat the same grind.

Roughing ouges should be sharpened with the Pivot Leg at position # 1 and
at a bevel angle of 45 degrees.
This will result in a finer edge towards the wings of the gouge than at the
centre, but the tool will operate just as well as one with exactly 45 degrees
across the whole edge.
The end of a Spindle Roughing ouge should be straight across - no grinding
back of the wings.

Place the tool in the Tru - rind Toolholder
horizontally with the same tool protrusion
as other tools. Next lay the tool on the
wheel and adjust the pivot leg until the
point angle is approximately 35 degrees.
Rotate the Toolholder to sharpen the other
side.
Place your skew chisel into the Tru - rind
Toolholder with the blade vertical and the
point at the bottom. Adjust the protrusion to 2
inches or 50mm from the tool holder body and
clamp it down firmly. Put the pivot leg into the
rear base pivot position and lay the body on
its side. Adjust the Toolholder leg angle until
the cutting edge is horizontal with the face of
the wheel. Then lay it on the wheel and adjust
the base slide until the bevel angle is correct -
we suggest 22 degrees. Start the grinder and
commence sharpening. The more you move
the skew from side to side, the more radiused
will be the edge. The shape of this edge is a
personal choice. Rotate the Toolholder to
sharpen the other side.
P A R T I N G T O O L
T R A D I T I O N A L S C R A P E R
Place the scraper in the Toolholder protruding as before and clamp tight. Next
move the pivot leg forward as far as it will go i.e. position #9 ( where it is level
with the nose of the scraper ) . Place the pivot leg into the forward pivot position
on the base slide. Move the base slide in or out to adjust the bevel angle as
required ( enerally around 55 degrees ) .
Apply the scraper to the wheel and rotate
until your preferred shape is achieved.
This method can also be used to sharpen
Ring Tools used for hollowing.
