Making things from timber

A design can be made as a one-off by hand, or in the thousands on a production line. The way a timber product is cut, shaped and made depends on how many are needed. This module covers the main cutting and shaping processes, the four scales of production, and the techniques used to make many identical products accurately.

Cutting and shaping

Key processes for working timber:

Match the process

  • Sawing
  • Routing
  • Cutting a mortise
  • Using a bag press
  • Cutting timber to size or shape
  • Cutting grooves and shaped edges
  • Making a slot for a mortise-and-tenon joint
  • Pressing veneers into a curved laminated shape

Which process?

Which process is used to make a curved shape by pressing thin layers of veneer over a former?

  • Using a bag press
  • Sawing
  • Routing
  • Cutting a mortise

Scales of production

Put the four scales of production in order, from the SMALLEST quantity to the LARGEST.

  • One-off: a single, often bespoke, item
  • Batch: a set number of identical items
  • Mass: large quantities on a production line
  • Continuous: made non-stop, day and night

One-off vs mass

The two extremes of production suit very different products.

Choose the scale

A carpenter makes a single, unique dining table for one customer. Which scale of production is this?

  • One-off production
  • Batch production
  • Mass production
  • Continuous production

Making many the same

To make many identical products accurately, manufacturers use special techniques: - Jigs, fixtures and templates guide the tools so every part is the same - Marking-out from reference points, lines and surfaces keeps parts accurate - CAM (computer-aided manufacturing) and sub-assembly speed up production - Quality control and working within tolerance keep parts within allowed limits, while efficient cutting minimises waste

Quantity-production techniques

Select the TWO techniques used to make many identical timber parts accurately.

  • Using a jig to guide the tools
  • Using a template to mark out each part the same
  • Measuring by eye each time
  • Designing each part differently

The processes in words

Timber is cut to size by _____ and shaped with a _____. A single bespoke item is made by _____ production, while huge numbers of identical items are made by _____ production. To keep every part the same, workers use jigs and _____.

Spot the shaping processes

Tap the TWO processes used to CUT or SHAPE timber.

  • Routing
  • Batch production
  • Sawing
  • Quality control
  • Continuous production

Choose the production scale

Recommend the best scale of production for each situation.

  • A student designs and makes one unique wooden clock for a project. Which scale is this?
  • A workshop is asked to make 200 identical wooden stools for a school. Which scale fits best?
  • A company makes millions of identical flat-pack shelves sold worldwide. Which scale fits best?

Choose and justify

A small furniture maker has an order for 50 identical bookcases. Recommend a scale of production and justify your choice. Write in clear, full sentences.

  • Name a suitable scale of production for 50 identical items
  • Explain how that scale works
  • Justify why it suits this order, rather than one-off or mass production
  • Name one technique that would help make the 50 bookcases identical
