This tool, designed by Len Grantham, is ideal for hollowing in end grain. It is easy
to use and provides a less expensive, but very effective, alternative to some other
tools on the market intended for the same purpose.
The secret of the tool lies in the precision made cutter. This is attached to the
square tool shaft at a pre-set angle. To use the tool one of the faces of the shaft
is placed on the tool rest so that the cutting edge is at an angle 45 ° to the horizontal.
The tool is used with the handle slightly above the tool rest. In this position the
cutting edge automatically takes up the required attitude for a slicing cut. This
makes the tool very easy to use. The tang of the shaft is machined to a cylindrical
form which means that it can readily be fitted to a conventional wooden handle or
to one with a collet fixing.
The high-speed steel cutters require sharpening relatively infrequently as they can
be rotated by degrees as the edge at the cutting point dulls. When a cutter does
require sharpening it can be returned to the factory where it will be resharpened
for free. All that you will be charged is postage and packing.
The tool is available in two sizes - one has a cutter of ¾ inch (19 mm.) diameter,
the other ½ inch (12.5 mm.) diameter. A spare cutter, a spare fixing screw and an
Allen Key, are supplied with each tool. Additional cutters are available.
Traditional Ring Tool
This tool comes in two bore sizes: 7/16 ins. (11 mm) and 5/8 ins (15 mm).
It is not a tool for beginners but, once mastered, is excellent for hollowing end
grain. It works extremely fast and cuts very cleanly.
