Lathe Thread Information...
1. Register diameter.
2. Register length.
3. Thread diameter.
4. Combined length of thread and register.
5. Thread pitch, either threads per inch or thread pitch if metric.
This table lists all the stock thread types which can be used
when ordering any of the threaded items, such as chucks,
chuck backplates, faceplates and screw chucks, from the
catalogue. If you are uncertain about which thread to specify
please ring our Technical Department who will be pleased to
help. They will need to know either the make of the lathe or
the dimensions of the lathe spindle as shown in the diagram.
The column heading numbers refer to the dimensions in the
diagram as follows:

When we started producing the Axminster Chuck, we ran into the immediate problem, “which
lathe should it fit?” So that we had greater flexibility, and could give faster response times to
our customers’ orders, the original chuck was manufactured as a ‘chuck body’ with an
interchangeable selection of threaded inserts to cater for the diverse range of headstock
mandrel threads produced by all the different lathe manufacturers. However, recent research
into our sales records showed us that approximately 90% of our sales have been for chucks
with the T01 or the T04M inserts. We decided that if we produced the chucks with the bosses
pre-threaded to these sizes we would be able to cut production costs and pass this saving on
to our customers. This we have done, (including passing on the cost saving!). However, we
realise that there is still that diversity of headstock mandrel threads ‘out there’, so we still
carry stock of the chuck body and a large range of the different threaded inserts, so everyone
can enjoy the wide scope and flexibility of the
AXMINSTER TURNING SYSTEM
no matter
whose lathe they turn on.
Note. A comprehensive list of the generally available lathes with their
headstock mandrel threads is available in the ‘Woodturners’ section of our
catalogue.
Improving & Expanding the Range...
Demand, progress and innovation have resulted in the continued improvement and
expansion of our existing product line. The introduction of anti-corrosion plating has also
furnished us with a distinctive new livery and a mammoth investment in our machine shop
has enabled us to improve machine finishes and maintain tolerances whilst working at higher
rates. The introduction of the integral mounting thread has also allowed us to decrease
production times.
We have also expanded the range to include an 80mm keyed version of the standard
Axminster Chuck, as well as keyless versions of both the 100mm and the 80mm chucks.
The introduction of the 80mm version has also brought about the production of a smaller
(physical size) range of the mounting jaws, for use with the smaller chucks on the smaller
lathes. The three new chucks are available with integral mounting threads T01 (3/4" x 16 t.p.i.)
or T04M (1" x 8 t.p.i.). All 80mm jaws will fit all of the larger chucks in the Axminster range.
