Entering the wood

There are three ways in which I make the first contact between tool and wood supported entry, direct entry and floating entry. The method I use depends on the cut being made. Direct entry with the deep-fluted gouge Skew chisel Shallow-Noted Shallow tiuteC Deep-tluted There is spacc to put the tool on the rest before controlled contact is made with the A-ood Supported entry A supported entry is one where the first contact between the tool and the wood is with the bevel.

How To Make Sliding Vee Miters

This a series of pointing cuts, as in a chamfer, on alternate sides of the vee. As general procedure with 1 Draw three lines on the wood Min (6mm) apart to represent the vee. Then intermediate lines not more than ' icin (1mm) apart. 2 Line up the chisel square to the axis, raise the point (about 2CT-30'), then, firmly and slowly, push the point into the wood. This does not produce a shaving, it just creates space for the further cuts. 3 For a narrow vee, swing just to the next mark on one side,...

Height

Lathes are a bit like clothes - they have to 'fit' the turner to get the best out of them. A lathe has a fixed height and you probably don't even think about it. However, it can make an enormous difference to your ability to turn. If it is too low then you have to stoop over the lathe, too high, and you don't have the manoeuvrability or power behind the tool. These problems can be solved by either raising the height of the lathe, or increasing your height, which is easy enough. It's simple...

Making direct entry cuts

Mount a piece of softwood, 2' zin (63mm) square - equivalent to 3l sin (89mm) diam - and lOin (254mm) long, between centres. Set the tool rest to in (19mm) below centre height, ' in (12mm) away from the wood and projecting 2in (50mm) beyond the end of the wood at the tailstock end.

Varnish and lacquer

Basic Woodturning Techniques

In its most basic form varnish is made up of a binder that is naturally solid at room temperature, dissolved (or suspended) in a solvent. The binder is either resin, lacquer or cellulose. When applied to wood the solvent evaporates, leaving the binder on the surface. Resins and lacquers are solid (or semi-solid) amorphous substances exuded from certain trees, primarily the lacquer tree. Slower-drying natural lacquers contain oleoresins.

Angles and cutting edge shapes

Woodturning Chisel Angles

The bevel angle is the angle between the bevel and the axis of the tool. The angle of the bevel has a number of effects. It defines the tool edge angle' except on chisels, which are sharpened on both sides so it is the sum of the bevel angles . It is also the cutting angle on gouges when the bevel is in contact v ith the wood. The bevel angle determines the strength of the edge - larger angles have stronger edges. A 45' bevel is a good strong edge. Anything less than 30s and the edge is a bit...

With the regularity that turning tools need to be sharpened, a powered sharpening system is called for. There are four basic methods of putting an edge on woodturning tools wetstone grinders belt or disc grinders high-speed grinders and honing. The following considerations, which contribute to the ability of the system to deliver sharp and well-shaped tools, apply to all four systems. Below It Is important to sharpen took regularly.

Stock shape

Rectangular or square stock is used for scrapers, parting tools, sizing tools and chisels. It's the way the stock is sharpened that defines what type of tool it is. In virtually all cases the bottom corners should be rounded so that they slide easily over the tool rest without damaging it. The 'oval skew' is a further development on rounding the corners and it is a nice tool to hold. If the stock is round and has a flute then it is a gouge. The shape of the flute determines what type of gouge...

Belt and disc grinders

While belt sanders are mainly used by woodworkers for sanding wood, Sorby now make one specifically for sharpening woodturning tcols. It is not a new idea as some tool manufacturers use belts for tool shaping and sharpening in their production process and some woodturners have also used them for tool sharpening. Belts and discs have a number of significant advantages they leave a flat bevel on the tool the belts keep their shape and don't need dressing, and they can be quickly changed for...

Sizing Tool

Using the sizing tool in conjunction with a pair of callipers. I wouJd recommend rounding the ends of the callipers so that they run smooth over the wood and don't dig in. Present the sizing tool horizontal in the same way as the parting tool. Tool rest XXin away. XXin below the axis. Hold the tool with a power grip in the control hand, and the callipers in the support hand. Start the cut by pushing the tool into the wood, then, v ell before the cut is down to size, gently rest the callipers in...

Curved edge skew

The curved skew is used in exactly the same situations as the straight skew, with the addition of two particular situations. Squaring the end of a spindle using the long cutting edge, the curve of the edge creates clearance at both ends, making it a safe cut. The second is making a smoothing cut into a corner, the edge can be swung round so that the curved edge completes the cut. Turning to a corner with a curved or straight skew Straight skew poshed up to br -g cut on to th point Curved skew...

Between centres

Homemade Woodturning

Centres are usually fitted into the lathe by means of morse tapers, which can be quickly and easily fitted, then removed with a knock-out bar. The traditional drive centre has four prongs or 'dogs' with a fine centre-locating point. This centre point should protrude about 'Ain 3mm beyond the prongs, to locate the drive centrally, and have a fine point so that it penetrates the wood easily, allowing the wood to be pushed positively onto t he prongs. Production turners would use an even longer...

Gouges and chisels

Woodturning Techniques

Control is achieved through the contact of the bevel on the wood, behind the cutting edge in the direction of cut. There are two elements to control the forces on the tool and the direction the bevel is facing. By applying a force along the tool handle with the control hand, there are two forces created between the bevel of the tool and the cut wood surface. The first is what I call a stability force, v hich is 90 to the bevel and keeps the bevel on the wood. The second is a feed force, which...

Accidents do happen

Even if after taking all necessary precautions, you do have an accident, be piepared to deal with the consequences. Keep a first aid kit handy even some first aid training would not go amiss. Keep a suitable fire extinguisher by the exit or better still, in an adjacent shed. Don't forget that they need regular maintenance and validating. Keep a telephone handy to call for help. And if all else fails, have a good insurance policy.

Using general principal

Woodturning Form Tools Rake Angle

The heal of the support hand is on the tool rest while the tips of the fingers are on top of the scraper in a fingers grip. The first contact of the scraper on the wood should be with a floating entry, the cutting edge just touching the wood as the tool slides along the surface with a light but firm touch. The weight of the tool is a great help. Once contact is made, always keep the tool moving, sliding backwards and forward over the surface to refine the shape. At the end of the cut, gently...

Curves

Sanding aids

Sanding aids make it easier and quicker to sand the surface and any troublesome areas. They can also help achieve a better surface and can be used as a base for the final finish. The choice of sanding aid depends on its compatibility with the final finish to be used. A sanding sealer is a varnish that contains about 20 fine solid particles, traditionally wood dust, to fill and seal the open pores of the wood and create a smooth surface. It also hardens any loose or torn grains and makes them...

Waste blocks

These are glued to Ihe blank and used for chucking to avoid wasting gcod wood. The bowl blank is held on the top with a faceplate, the bowl is roughly shaped and a flat area is made on the bottom. Whichever glue you use, allow time for it to 'cure'. If a strong glue is used it might be advisable to put a piece of brown paper between the glued surfaces so that they are easier to separate. The waste block can be turned and a very shallow recess made, which would locate the faceplate centrally so...

Jam chuck

Jam Chuck Lathe French

Jam chucks are used for holding a bowl on the inside or outside of the rim to enable the base to be turned and finished. This has to be accurate and made to suit each bowl. Turn a spigot with a slight leading taper. Hold the rim of the bowl on the taper if it goes on almost to the straight section, then a light tap should push the rim on the spigot. If it is slightly slack, then put a piece of paper or cloth over the spigot to make Ihe fit secure. Rotate wood m opposite direction to lithe...

Homemade chucks

One of the pleasures of turning is the challenge of making your own chucks, allowing you to be inventive and save money. If you come up with something good, there could also be commercial prospects. Most forms of home-made chuck are adaptations of existing chucking methods. The jam chuck is one of my favourites. I use a small one to hold solid fruit so that I can finish turning the bottom. It is a 20' tapered cup. with a wall thickness of about ' in 6mm so that there is some give as the fruit...

Dust extraction

Whatever kind of wood you are using, a dust extractor is a must - the more powerful the better. However, watch the noise level if the dust extractor is going to be in the workshop. Not only will it create another hazard, a noisy dust extractor will be switched off at the earliest convenience, or more likely not switched on at all. Dust extractors should be able to collect dust down to 5 microns. Old double-bag type extractors may not be capable of this and will recirculate the fine, dangerous...
