There are a good many excellent books on
the subject of Woodturning, some of which are directed specifically at the beginner. As a second to standing 'at the master's elbow', then reading these must be considered very beneficial. A couple of my personal
favourites are: 'Woodturning - Two in One'; by Phil Irons and 'Woodturning: A Foundation Course'; by Keith Rowley. Both these are very readable books being presented in a 'light' style - but are no less helpful and
competent for that. If you are ready to delve deeper into the esoteric world of woodturning then an excellent place to start might be: 'Turning Green Wood'; by Michael O'Donnell, originator of many of the tools and techniques
used many woodturners around the world. (You'll notice from the titles of these three books how imaginative woodturners-turned-authors are when it comes to selecting titles for their masterpieces! Happily their
imaginative content belies their stolid titles - in my view. At least this makes searching the catalogues at your library or bookshop easy.) All of these authors are also teachers of woodturning of high repute and
long experience, so they really know what they're talking about. So that's two lessons already:

All of these books spend some time
covering the safety aspects of turning and should be taken seriously even if for this advice alone. Much safety advice could be considered 'common sense' but, as we hear so often, common sense is a very uncommon
commodity. In general then:-,
In addition to these general safety rules, which apply equally to the use of any machinery, there are 'rules' specifically related to the turning of wood which need to be followed whenever
you're at the lathe. Although we're a way off the actual turning yet, let's lay them out now so that they have time to sink in before you need to use them! Don't worry if you don't know or understand all of the
terminology yet, it should all become clearer with time. These basic That will do for now. Is it becoming clearer why the best way to learn is to watch an experienced turner and to take instructions from a living, breathing human being? Maybe now is the time to look at the list of

The spindle on the lathe is mounted in bearings in the headstock and is caused to rotate by the motor. The headstock assembly is mounted on the lathe bed, which is the support which keeps all of the components of the lathe rigidly aligned. At the other end of the lathe bed is the tailstock, which supports the end of the workpiece and which can be moved along the bed to suit different lengths of workpiece. The tailstock usually also incorporates a sliding barrel, or 'quill' which can be moved in and out by turning a handwheel, thus giving fine positional control and enabling end-loading to be applied to the workpiece. Also movably mounted on the lathe bed is the toolrest saddle which supports the toolpost and toolrest. The toolrest saddle - sometimes also known as a 'banjo' because of the shape of this part on earlier lathes - is moved into position such that the tool can be rested on the toolrest and reach the workpiece with full support. And that's about it for the essentials. Many lathes don't have any supporting structure beneath the bed and need to be mounted on a robust table or bench. Others come complete with a floor standing frame, or may indeed be integrated designs. Speed changing is normally effected by moving belts onto different-sized pulleys but many newer lathes now incorporate electronic variable speed systems and a few have mechanical speed variation systems - like the one in our photograph which shows a PooleWood PW28-40 heavy duty lathe. |
The workpiece may be held in a number of different ways. Most commonly, especially for 'spindle work' such as chair legs, the work is held between a driving centre mounted in the headstock spindle and a rotating centre mounted in the tailstock barrel. For flat work such as platters and bowls, it is normal to use a faceplate onto which the work is attached by screws, before the faceplate itself is mounted onto the headstock spindle. Most turners now also have one or more chucks, which are mechanical devices which hold the workpiece by either contracting jaws onto the work, or by expanding the jaws outwards to hold in a recess formed in the work. Although the chuck is a relatively new addition to the armoury of the turner (in terms of a craft with a known history of more than three thousand years!), most would now say that their chuck is an indispensable, albeit somewhat costly, device. Work of this nature, where the diameter of the workpiece is large in relation to its thickness and where the piece is normally mounted from only one side, is known as 'faceplate' turning - even if you use a chuck instead of a faceplate. |

Skew Chisels |

and rectangular cross-sections and in both large (1"/25mm) and small (½"/12mm) sizes. The skew chisel is used 'lying' on the workpiece with its edge forming an angle of around 45º with the axis of the workpiece; the bevel is positioned to rub on the rotating work and the point of contact/cutting should be in the centre to lower half of the cutting edge. It's a tool that may be best left until someone can demonstrate it to you, rather than trying it out 'in the privacy of your own workshop'. The edge of the skew chisel is normally ground to give an included angle between 60º and 80º although some turners prefer a much finer angle. This is a very versatile tool which is also used for cutting across the ends of spindles to face them level, for making vee grooves - and even some things they were never designed for! The name 'skew' chisel comes from the fact that the cutting edge is 'skewed' (angled) at around 70º to the longitudinal axis of the tool; there are also straight chisels (not to be confused with firmer chisels used in carpentry) but these are little seen these days and few manufacturers still produce this older design though they are available through The ToolPost |
Spindle Gouges |
|
|
Note that these tools, like the roughing gouges are of semicircular cross-section, but the 'flute' - the groove running the length of the blade - is shallower, thus leaving more material in the blade, making it stronger. Such gouges are normally forged from solid high-speed steel (HSS) bars giving them great rigidity. The cutting edge of a spindle gouge can be ground to any angle between around 30º to 45º, depending on personal preference and turning style. Most turners now grind their spindle gouges to what is colloquially termed a finger-nail shape (a rather well-manicured lady's finger-nail, it must be said) as this makes the tool more versatile in use. The gouges shown here are 'hot off the mill' and have not been re-ground to suit individual preferences yet. However, if you look critically, you will note that even with this standard grind, the top edges of the flute are set back a little from the bottom centre of the flute. The ToolPost |
Parting & Beading Tools (including the Bedan) |

version of the parting tool. It is parallel-sided, around ¾" (19mm) deep and 1/8" (3mm) thick. It is used with the narrow edge resting on
the toolrest and the broad side standing vertically; the presentation to the timber is perpendicular to the axis of rotation. The next development is the diamond-section parting tool, developed to minimise the friction
generated between the tool and the sides of the parting cut. This is achieved by grinding the top and bottom edges of the tool away to leave a truncated diamond shape in cross-section. Hence although the cutting edge is
full width at the tip of the tool, the sides only contact the groove on the tool's centre-line. Use is similar to the standard parting tool. The fluted parting tool is a yet more recent development and is designed to
give cleaner parting cuts which are less likely to need the attentions of a skew chisel to clean them up. An example is shown third from the left in the photo and it has been turned slightly onto its edge to make the groove
more obvious. In this case the tool is presented with the groove downwards onto the toolrest and care must be taken to confine any grinding to the bevel only, leaving the groove untouched. (the groove runs the full
length of the tool blade). All three of these tools are ground to give an included angle of around 60º to 90º, although the fluted version has only one bevel to grind. Finally, we come to the beading and parting tool on
the right-hand side of the photo. This is like a square-section parting tool: it is broader and shallower than a parting tool, the example here being 3/8" (10mm) square in cross-section. This tool is normally used
for shallower cuts than the parting tool and is especially useful when forming 'beads' - convex humps standing proud of the surface of the workpiece. It can also be used as a small straight chisel in place of a skew for
finishing short tenons and parallel details. I wouldn't be without one. The grinding angles follow those for the parting tools. |
Bowl Gouges |

are ground square-across, not ground back towards the upper edges of the flute (the 'wings'). There are probably more variants on the grinding of bowl gouges than any other and I'll make no attempt to describe them here, but suggest that you go to watch as many good turners as possible and ask them how and why they choose the grinds that they use. The essential feature of the bowl gouge is that it should be very rigid as it is often used with quite a lot of the tool overhanging the tool rest. Bowl turning is also a pretty tough business, so the tools need to be robust if they're to perform well. Such gouges are ground to a fairly obtuse angle, between 40º and 55º, depending on the internal form of bowl which you favour - we're getting into deep water here! Every turner will have his own favourite bowl gouge style and much of the decision of which type to buy will depend on the shape of the internal flute and its effectiveness at clearing shavings. Try as many as you can before making a final decision - if you can - and then learn to use your chosen style effectively. Your local supplier: The ToolPost |
Scrapers |

and used 'scraper' should cut and produce real shavings - not just dust - just like any other properly-sharpened turning tool. Scrapers come in many and varied shapes and are often reground by turners to suit individual jobs and special applications. The examples shown in the photograph give some idea of the wide variety of shapes in common use. On the left is the bowl-turners favourite, the domed scraper. If you buy one, buy a big, heavy cross-section type: you won't regret it! Lightweight scrapers are 'rippled surfaces looking for somewhere to happen'. This particular one is 1¼"x¼" (32mm x 6mm); my favourite is 1½" x 3/8" (38mm x 10mm) and I'd buy even bigger if they existed - at an affordable price. There is no substitute for rigidity in a scraper. The middle tool is a box, or diamond side-cutting, scraper designed for - yes - finishing the inside bottom corners of cylindrical boxes. Because such tools are often used in confined spaces, they are normally somewhat lighter in section than bowl scrapers; in this case ¾" (19mm) wide. The final tool shown here is the square-ended scraper which is very useful on flat work such as platters and tabletops - if used with care and skill. This is a partner to the domed scraper shown on the left and of the same heavy cross-section. In addition to its use on flat surfaces, the square scraper can be used on the concave outer surface of bowls where you may find it useful to remove ripples and undulations. (Sorry: I get ripples and undulations in my work sometimes, I just thought other folk did too?) As for grinding, the scrapers are normally ground with a cutting edge just off vertical: that is, at 80º to 88º with reference to the top surface. In fact it is the burr thrown up on the top edge by the grinding process that is the actual cutting edge, rather than the corner formed between the bevel and the top surface. But again, as you get more into woodturning you'll find there are many opinions about that too. For now, believe me, the burr theory works! Many different variteies of scraper are available from The ToolPost |
