Woodturners’ Dimensioning Tools
A collection of tools designed for the woodturner to measure wall thicknesses,
internal and external dimensions.
THREADING AND SIZING GAUGE
Ideal for box-makers, this gauge takes all the
guess-work out of fitting the major and minor
diameters of pieces. With the gauge set at the
unmarked anvil this creates a 1:1 correlation
between the measuring faces and facilitates
accurate push fits.
The other three anvils are marked 10,16 and
20 which relates to the tpi most commonly
used by thread cutters. The gauge has a built-in
compensation factor to ensure a perfect thread
between internal and external diameters every
time.

VESSEL CALLIPERS

These vessel callipers are designed for internal
and thin-wall dimensioning.
The straight arm is especially useful for
accessing narrow vessels. Sizes can be read at
either end. Available in 2 1 ⁄ 2 ", 5" and 10" models.

Sizing Tool
These are an indispensable addition to the
turner’s armoury for measuring both wall
thickness and diameters. Because of f
their design the measurement taken
at one end automatically transfers to o
the opposite end.
This enables the turners to take an
accurate measurement reading without the need
to remove the callipers.
Available in 4" and 7" models. The 7" version
has an increased depth of throat at one end
which permits the callipers to be used in large
diameter vessels which have restricted openings.

4" Double-ended Calliper
INSIDE / OUTSIDE CALLIPERS
The design of these callipers allows not
o only the measurement of wall thickness but
a also inside dimensions like the size of an
a aperture. As with double ended callipers the
measurement at one end automatically transfers
m
t to the opposite.
Available in 6" and 8 1 ⁄ 2 " models.

e either the Robert Sorby 3 ⁄ 8 " beading and parting
tool or bedan.
The two thumb screws lock the sizing tool firmly
in place.
