1 Chucks xminster Chucks xminster has been producing 4-jaw chucks for woodturning lathes since 984. The English company offers a suitable chuck size for every application, not to mention excellent value for money. The chucks along with all accessories are made in England on CNC machines and have been developed over years working closely with experienced turners. a xminster Woodturning Chuck Evolution SK4 This chuck features a super-slim stainless steel body incorporating a new design of longer accessory mounting jaws. Max. jaw movement 22 mm (plus safety capacity). Fully compatible with all xminster jaws. Includes chuck key for one-handed operation.

Size 240 mm No These jaws sit deeper in the chuck and offer a greater contact area within the slide ways of the chuck, thus minimising vibration during use. Indexing is achieved by 24 peripheral slots and 36 holes on the chuck back plate, giving the option of 0 or 5 indexing. c xminster Woodturning Chuck, Evolution SK4 SOLO Model M33 x DIN 800 Ø 4 mm No Evolution Standard The ultra-compact design keeps the workpiece as close as possible to the headstock of your lathe to lessen the load on the bearings and prevent unwanted vibration.

The self-centering 4-jaw chuck is highly robust and versatile. Its extreme stability is supported by large threads in the scroll and jaws. The chuck body is made completely of stainless steel, which allows closer manufacturing tolerances. This ensures better concentricity and minimises vibrations. The max. jaw movement is 25 mm (plus safety capacity). Includes chuck key for onehanded operation. For safety, the maximum jaw movement is limited so that when the chuck is fully opened, the threads of the scroll engage still sufficiently in the jaws.

5 How to find the appropriate Oneway adapter for your lathe Why you should always measure the thread of your spindles There are many lathes on the market and they all have different thread sizes on the main spindle. To obtain the appropriate accessories (e.g. faceplates, woodturning chucks or adapters), it is vital to know the thread size of the main spindle. Required measuring tools metric precision calliper with /0 display accuracy or a calliper with inch display. efore measuring the thread, check in the manufacturer s manual or operating instructions whether you can obtain information on the thread from them. If necessary ask the manufacturer. Information on the model, and where appropriate the year of manufacture of the lathe will be very helpful. If no information on the thread size is available, proceed as follows:. Measuring the outer diameter of the thread In this instance it is important to determine whether the thread is a metric or an inch thread. One inch equals 25.4 mm mm thread would therefore be a metric thread (for metric thread sizes see Table ). It is very important to measure carefully here and read the measurement off accurately. For outer thread diameters see Illustration 3, measurement. Typical metric threads are: M8, M20, M24, M25, M30, M33, M40. If you find diameters with decimal places, the thread is an inch thread. The mm - inch conversion can be found in Table Measuring the thread pitch With a metric thread this is the gap from thread crest to thread crest (see Illustration 2); for thread pitch see Illustration 3, measurement. In the case of an inch thread it is the number of thread crests (also called turns) per inch, i.e. per 25.4 mm, which is determined. This is described as tpi (threads per inch). Illustration Illustration 2 3. Measuring the flange With some machines the flange can have a greater diameter than the thread itself. Measure the diameter of the flange as well (see Illustration 3, measurement C). 4. Determining the thread s direction of rotation With a RH (right-hand) thread the thread flanks rise towards the right when viewed from above, and with a LH (left-hand) thread towards the left. It is also possible to have RH/LH threads that are cut twice. Illustration 3 Table : Metric thread Ø in mm Gap in mm from thread crest to thread crest Metric thread sizes M8 x 2, M20 x M20 x, M24 x M25 x M30 x M30 x M33 x 3.5 DIN 800 standard on most lathes 40 6 M40 x 6 e.g. sweden dditional Information Thread form or flank angle of thread turn UNC, UNF /NF and metric threads (also called ISO threads) have a 60 angle Whitworth, SW, and SF threads have a 55 angle Metric or ISO Thread UNC (Unified National Coarse Thread) Designation e.g.: M33 x 3.5 means: Diameter 33 mm, pitch 3.5 mm. Designation e.g.: - 8 UNC means: Diameter inch - 8 turns per inch thread length.

Designation e.g.: 3/4-0 WS means: Diameter 3/4 inch - 0 turns per inch thread length. SF (ritish Standard Fine Thread) Designation e.g.: - 0 SF means: Diameter inch - 0 turns per inch thread length. 29

6 Jaws for Talon and Stronghold The Oneway chuck jaws are equipped on the underside with a guide pin which engages with a guide groove in the body of the chuck. This is an important safety feature. Inadvertent unscrewing or exceeding the maximum clamping distance could in the worst case lead to flying jaw parts. 2 Oneway Jaws, Premium Profiled Serrated Serrated jaws are used during all standard clamping situations. It is possible to fix workpieces by clamping or spreading them. The serration on the inside of the jaws safely fixes the workpiece. The shape of the inner jaws is not completely round but angled. This patented design enables the jaws to safely clamp square stock and minimizes the damage of the surface. The jaws also have more contact points than conventional serrated jaws when clamping round stock. This enables a higher clamping force.

8 Chucks The Robert Sorby company has been known for its range of highquality woodworking tools for over 200 years. In Sheffield, England, traditional working methods are combined with technical expertise. This guarantees sophisticated tools with a quality that speaks for itself. Sorby Eccentric Chuck RS60 The excenter chuck from Sorby allows you to turn countless detailed and unusual figures and shapes with complete safety and precision. It is possible to produce items in batches thanks to precise repeatability. The axle offset can be set and read with infinite variability from 0 to 35 mm. The Sorby excenter chuck makes use of a counterweight to keep the workpiece as balanced as possible. This provides more stability, protects the stock and reduces the risk of an accident. The three well-engineered clamping methods (with the help of the included face chuck, screw bolt and hexagonal nozzle) gives you great flexibility. Working without a tailstock is also possible.

9 Robert Sorby clamping devices The sprung stainless steel tip and sharp teeth that bite into the wood will guarantee optimal hold. This works even on lathes where the axles (spindle stock to tailstock) are not 00 % aligned. Safe working is guaranteed. The geometry of the teeth also makes this exceptionally good for tensioning unusual shapes. To do this, the piece is tensioned between the Sorby revolving stepcentre and a Sorby driver. a Sorby Stebcentre Spur Driver, #2 MT Overall length 00 mm Ø 3 mm No mm No mm No a 2 3 b Sorby Steb Chuck Driver Saves time and effort: The Sorby Step Driver can be easily placed and clamped on your current chuck.
