The McNaughton Centre-Saving System: Timber isn't cheap. Good, attractive timber is positively expensive. So why do we happily
convert most of it into shavings on our workshop floors? Primarily because we believe we have no alternative. That may have been true before the advent of the McNaughton Centre-Saving system but this clever
and versatile tool provides a realistic way for you to "core out" blanks from within your turning timber, creating extra material for you to use at no extra cost. Hugely popular with professional turners and
recently described as "the turning tool of the century" here's a real opportunity to actually reduce the cost of your hobby. Imagine getting four bowl blanks or even two or three – but why not five or six, out of
your source material? We now supply the latest, Mark 8, version of the McNaughton system which features a brand new toolpost/guide yoke assembly with extended functionality as well as now incorporating a
hollowing gate. There are now two sizes of gate assembly as well as four sizes of blades giving the system even more flexibility. Five configurations of this great tool are available. Each includes a pin
gate, restraint yoke, toolpost, handle and a selection of blades, as follows:-
- Micro set: 3 curved blades plus one straight blade of 1/8" x 5/8" cross-section. The four pin gate supplied accepts both Micro and Small centre saving blades and the integrated hollowing gate can be used
with Kelton 5/16" hollowers.
- Small set: 3 curved blades plus one straight blade of 13/64" x 3/4" section. The four pin gate supplied accepts both Micro and Small centre saving blades and the integrated hollowing gate can be used with Kelton
5/16" hollowers.
- Standard set: 3 curved blades plus one straight blade of 1/4" x 1" section. The five pin gate supplied accepts Small, Standard and Large centre saving blades and the integrated hollowing gate can be
used with Kelton 5/16", 1/2" and 5/8" hollowers.
- Large set: 2 curved blades plus one straight blade of 1/4" x 1.1/4" section. The five pin gate supplied accepts Small, Standard and Large centre saving blades and the integrated hollowing gate can be used
with Kelton 5/16", 1/2" and 5/8" hollowers.
- Combined set: 3 curved blades plus one straight blade from the Standard set AND 2 curved blades plus one straight blade from the large set with the five pin gate described above.
Because this system is so flexible in terms of the size and shape of core that can be taken with any particular blade, it is difficult to specify any sort of exact size range for each set. The following
guidelines, whilst by no means "absolute" may help.
- The Micro system has been dsigned to cater for those who work in valuable tropical and exotic timbers and whose work is probably in a size range from 4" to 8" diameter
- If you typically work with blanks in the size range 6" (100 mm) to 10" (250 mm) diameter, then the Small set will probably fulfill your needs.
- For work in the 8" to 14" (200 mm to 350 mm) range, then I would opt for the Standard system.
- If you routinely handle work in the 10" to 18+" (250mm to 450 mm) diameter range, then the Large set is for you.
Note that additonal blades may be purchased to extend the range of your basic set, up or down and that there is considerable overlap between the sizes of cores that can be taken with the different sets.
Please note that the system will be supplied with a 1" diameter toolpost stem unless you specify otherwise in the "additional Information"
section of the checkout. Spare toolposts are listed below and this list indicates the toolpost sizes available. |

Whilst the centre saver is not a difficult tool for the competent user to master, it is certainly 'different' from most normal turning tools.
We found the excellent DVD produced by Mike Mahoney on the Centre Saver to be a great way of learning to get the best from the Kelton tool. There are hints and tips here that you might spend a lifetime discovering
otherwise.A second DVD is available, created by Reed Gary, which takes a somewhat broader and very personal view of the McNaughton Centre Saver system. This includes the use of the laser guide accessory,
available as an option, and some tips on "disaster recovery"!. Again, a very useful adjunct to ownership of the McNaughton system. |

Kelton Tool Handles: The wide range of specialist woodturning tools developed by New Zealand-based professional woodturner Kel McNaughton share a
common basis – the Kelton handle system. Choose from a range of rigid, comfortable, easy-grip handles with a choice of capacities, or the superb Ultimate Handle which offers the flexibility to fit just about any
interchangeable tool through its ferrule and sleeve/collett system. (NB: All handles will equally accept imperial or closest metric size tools. i.e. 5/16"=8 mm; 3/8"=10 mm; ½"=13 mm; 5/8"=16 mm; ¾"=20
mm) The second range of Kelton handles are the ER collett handles which utilise the readily- available standard ER-series engineering colletts, as used on collett chucks, to allow the handles to be fitted to almost
any size of tool. As their names suggest, the ER16 handle takes collets up to 5/5"/16mm whilst tyhe larger ER25 can handle up to 1"/25mm colletts. A stabilising side handle is also available. Just a
twist of the knurled ring is all it takes to lock the collett onto a tool or to release it. |
