Timber: Shape & Form

Cutting

There are many different methods of shaping and forming wood. This variety reflects the range of products that can be made from timber. The processes used for wood are cutting, drilling, sanding, chiselling and planing.

Cutting

Cutting can be done through two main methods:
- Hand cutting.
- Machine based cutting.
Hand cutting involves the use of different saws such as:
- Coping saw, tenon saw, dovetail saw, jack saw, pull saws and Japanese flush cut saws.

Saws

Saws all have handles and teeth to cut through the material.
The amount of teeth is measured in teeth per inch (TPI).
Saws are used to reduce the size and change the shape of a piece of wood.

Coping saw

Coping saws are used to cut curved lines.
It can be difficult to cut straight lines as the blade is thin which lends itself to curves and cutting circles.
The coping saw has 12-15 TPI.

Tenon saw

The tenon saw is great for cutting wood to form joints.
When creating finger joints it is a good saw to use as the blade is fairly thin and larger.
The tenon saw has 11 TPI.

Dovetail saw

The dovetail saw is similar but has much finer teeth, this is excellent for cutting dovetail joints which require precision.
The TPI for this saw is approximately 18.

Cutting with a saw

It is important to accurately mark the wood with a pencil and a ruler.
It is important to secure the wood (workpiece) using a clamp or a wood vice.
Once it has been securely clamped, you create a groove in the piece of wood by drawing your saw back three times on the marked area.
After your groove has been created, use the full length of the saw to push and pull the saw to cut the wood.

Drilling

Drilling can be achieved through:
- A pillar drill.
- Corded and cordless drill.
- Hand drill.
- A lathe with drill attachment.

Marking the wood

Almost all of the above methods will require you to carefully mark out the material with a ruler and a pencil, indicating the point you would like the hole to be drilled at.
Once you have made a mark using a ruler and pencil, ensure you double check the position as any mistakes can be costly, although they can be rectified.

Drilling wood

Using a centre punch or bradawl you can create a small impression on the surface of the wood exactly where you have pencil marked the piece of wood before.
The small impression allows the drill bit to take to wood safely and accurately.

Drilling wood cont.

Turn the drill on using the bottom or trigger switch.
The drill will start to rotate and cut into the wood.
You should take your time when drilling so that you don't damage the material.
