Considering grain when selecting timber
Timber grains come in a range of patterns. This depends on the way that the log is cut into boards.
There are numerous ways to saw logs, with common low-waste techniques being:
- backsawn
- quartersawn
- radial sawn
Each offers distinctive appearances, either embracing unique features of a tree that share its story of life in the soil or offering neat, uniform lines. Figuring out functional requirements and aesthetic vision of your design will help you to make the right choice in selecting timber.
Backsawn:
This type of sawing minimises waste of the log and allows for wider boards to be cut. You'll have seen backsawn wood before in furniture surfaces that display an attractive grain pattern of arching lines. Each pattern is unique and brings visual interest to a design, with a warm, rustic feel.
Backsawn timber is less prone to splitting when nailing.
Quarter sawn:
Quarter sawn timber is the smart, formal office attire type - not as laid back as backsawn. It's characterised by a straight even grain, in Oak species displaying ray flecks.
This process of sawing takes longer, where the log is initially divided in quarters before boards are cut. Compared to backsawn, quartersawn has lower shrinkage and is less likely to cup or warp.
Radial sawn:
Logs are first divided into wedges, following the way logs naturally split when drying. This type of sawing ensures high yield and low waste, particularly for smaller logs.
Though less common due to its longer sawing process, people choose this type due to its high stability and attractive grain detail. It's popular for fencing, cladding, decking and skirting.
The diagram on the right (sourced from Wood Solutions) shows how the log is cut for each saw type.
Ultimately, the grain pattern is a stylistic choice, with some considerations to be made about how the saw type will perform for the specific application.
Fair Wood largely supply backsawn, with quartersawn joinery also available, like the Manna Gum pictured.
