Woodworking


“Woodworking minus patience equals firewood.” - anon

What is woodworking?

It's the creation of objects from wood using hand or power tools. Woodworking is more diverse than it first seems - it includes everything from rustic green woodworking to intricate and precise cabinet-making. Carpentry is the name given to this activity by most people, but in the industry this refers more to the construction of structural woodwork in housebuilding which is usually carried out on site. People who make doors and windows and similar objects are called bench joiners and are usually based in a workshop. A good woodworker knows how to get the best out of different materials, from natural timber to plywood or strandboard. It's not just about proficiency with tools, but also design and planning.

Wood is such a workable material, with the simplest of tools, it would have been one of the first things humans used to create shelter and tools. There's a huge range of tree species, which come in different grades and for most conventional work must be dried to prevent movement after it has been worked. There are many different specialist woodworkers - for example, chairmakers, barrel makers, wheelwrights, shipwrights, woodcarvers and instrument makers. Each craft has its own specialised tools - for example chair makers have travishers for hollowing chair seats to make them more comfortable, and woodcarvers have a huge range of gouges for cutting different shapes. Woodworking techniques enable us to create things as diverse as houses, boats, furniture, shelves, doors, windows, animal housing, workbenches, utensils, picture frames, toys, containers and much more.

Woodworking encompasses a large quality range too - a piece of work can be held together with just nails, or intricately-made joints; wooden structures in houses are commonly held together with nails and screws, but a chair or an older house can contain mortice and tenon joints. Experienced woodworkers use a range of different joints for different scenarios, to resist the different forces exerted on the finished work. Examples of joints include mitre, bridle, finger, box, housing, dovetail, butt, tongue & groove, mortice & tenon, halving or lap joints. Some joints are easily done with hand tools, and others require power tools – such as biscuit or domino joints, which are designed to save time and are very strong.

What can I do?

To get started doesn't have to be expensive. Wood is a readily-available material, and sometimes free if you know a friendly landowner or tree surgeon, or if you recycle old pieces. We'd suggest that you steer away from MDF – it contains toxic ingredients like formaldehyde, and so there are health risks associated with cutting it. There are times when using other man-made materials like plywood makes sense – it's much more economical for making box-type structures such as wardrobes, kitchens and other cabinetry. Using solid wood in that situation can be difficult and expensive.

Attend a woodworking course to gain skills and the confidence that you know the right way to approach a job. You don't need lots of gear - just start, and it will accumulate over time. You don't necessarily need a dedicated workshop either. You can work outside for much of the year, but you need a dry space to store your wood, and something to work on. It can be a simple wooden box or bench - maybe one of your first projects could be to make a workbench.

Tools

Tools have to be very sharp - enough to take the hairs off your arm. Tools don't come fully sharpened when bought unless they are of a very high quality. They'll come with a ground bevel which needs to be refined with a sharpening stone of fine grade. There are different sharpening stones – such as diamond, ceramic or waterstones, and they each have their fans. The basic principle is to start with a precisely-ground, 25-degree bevel made on an electric grindstone or very coarse sharpening stone. You then progress to a finer sharpening stone and hone the bevel at 35 degrees, then hone the back flat and polish the result on a leather strop.

Most specialised tools have to be ordered from mail order companies unless youre lucky enough to live near a supplier. It's a good idea to cultivate a relationship with your local hardware store where you can also get advice on tools and techniques. Used tools from second-hand shops or specialist market stalls are great - but you need to really understand the tools first to avoid damaged or unsuitable ones. If you buy a set of second-hand tools, there are companies you can send them to to be sharpened, or again, you can try your local hardware store. Most old saws can be resharpened, but most modern ones can't. Find good quality old tools that can be sharpened - you don't want your tools to be disposable. Be wary of buying an old tool that doesn't look as if it's been used – it could be because it wasn't very good.

You can make a wooden toolbox to store your tools, so that they don't get damaged. A plastic one is useful if you'll be working outside, or a traditional canvas carpenter's bag is easy to carry. If you're using power tools you'll need goggles, gloves, dust mask and ear defenders.

Saws

A saw's teeth are alternately splayed (called the 'set'), to cut slightly wider than the body of the saw, so that it has room to move through the cut. If a saw tends to get stuck, it's lost its set. There are different saws for rough or fine work - the more tpi (teeth per inch) the finer the saw. There are saws for cross-cutting (across the grain) or rip-cutting (with the grain). A rip saw has fewer tpi and a larger gullet (space between the teeth) to help remove waste material.

Other useful tools

Figure 8: You can get perfectly good second-hand tools from market stalls or car boot sales; might be better to get some experience first, so that you can gauge the quality.

Sundries

You'll need a stock of 'stuff', or you'll have to keep running to the shops. Things like:
