When you visit Scottish Wood or order from our stock online, you’ll encounter a wide variety of Timber boards & Off-cuts. Whether you’re making furniture, doing joinery, crafting outdoor pieces or working on small DIY jobs, choosing the right piece matters. The wrong timber can lead to warping, waste, extra machining or maintenance. Here’s how to make good choices to get the most from your wood and your budget.
1. Know What You’re Using It For
Start with purpose:
Interior use vs exterior/exposed use: think about - different durability, moisture exposure, shrink-swell behaviour.
Interior (furniture, cabinets, flooring): Exposed to relatively stable temperature and humidity. Durability requirements are lower, and timber choice can prioritise appearance and workability. Kiln-dried timber is preferred for stability and reduced shrink-swell.
Exterior/Exposed (cladding, decking, outdoor furniture): Exposed to rain, sun, and fluctuating humidity. Timber must resist decay, rot, insects, and moisture-induced movement. Air-dried and naturally durable species are recommended.
Structural vs Decorative
Structural work demands sound timber with minimal defects.
Appearance-focused projects allow more character (knots, grain, colouring), but understand how features affect strength and finishing.
Finish & Machining
Rough-sawn boards need extra thickness for planing.
Planed boards or off-cuts may require trimming, joining, or sanding before use.
2. Species & Natural Properties
Scottish timbers bring great diversity. Some things to check:
Durability of heartwood vs sapwood: For example, Scottish Oak and Larch are naturally durable but sapwood can decay more rapidly if exposed.
Grain and Growth Characteristics: Straight grain is generally more stable and easier to work with. Figured grain (burr, curly, rippled) adds striking character, but because the grain direction changes, it may require sharper tools, lighter cuts, or careful positioning to achieve the best results.
Moisture content & seasoning: As mentioned Kiln-dried timber is more stable for indoor use, air-dried timber suits exterior projects where a slightly higher moisture content is acceptable.
3. Size, Straightness, and Flatness
These factors are often overlooked until you start working with the wood:
Straightness and Flatness
Check the board along its edge for straightness.
Ensure the surface is flat with no significant bows, twists, or cups.
Dimensions
Confirm that the thickness and width match your project requirements.
If you plan to plane or machine the wood, allow extra material to account for adjustments.
Defects and Board Quality
For long boards, note the location of knots, splits, or other defects.
Knots near the edges may be acceptable, can often add rustic character but depending on your project, defects in the middle of the board can weaken the timber or complicate joinery.
4. Grading & Defects
Understanding grading helps you balance cost vs quality. Some points:
Appearance grades: how clean the faces are, how many/sized knots, splits, checks, bark-pockets etc. (Hardwood grading guidance is useful here - Making the Grade)
Defects to watch out for: dead/loose knots, splits or shakes, rot, insect damage, warping.
Special features: quarter-sawn, pippy/character grain, spalting etc. These add visual appeal but may cost more, may be harder to match, may require more finishing but are highly sought after for their distinctive and unique appearance.
5. Off-Cuts: Hidden Gems When Chosen Carefully
Off-cuts are often lower priced, and perfect for smaller work or pieces you’ll see less of, but approach them smartly:
Inspect the end grain and faces: Are there splits or end checks?
Match with your main boards: Colour, grain, thickness, finish. Using off-cuts from the same kind of timber helps consistency.
Think of waste: Sometimes off-cuts look cost effective over longer pieces and boards but if you end up discarding most of them because of defects or mismatch, you lose the saving.
6. Allowance for Machining & Finishing
Even the “ready” board may need work:
Planing/surfacing: removes material; you need enough thickness initially to allow for that without going undersize.
Jointing/trimming: edges may be uneven; may need straightening.
Finishing/coatings: for exterior pieces or high-use furniture, factor in sealants, stain, or protective coatings - some timbers take them better than others.
7. Budget vs Value
You pay for what you get, but sometimes “more expensive” pays off in the long run:
Higher quality boards may save time in machining, yield less waste, less finishing work.
Durable species or heartwood may reduce maintenance and replacement.
Buying just a little more than you think you need gives margin for defects or mistakes.
8. When in Doubt, Ask Us
Every project and every piece of timber is unique. Sometimes the best choice depends on subtle factors like how a species behaves in the Scottish climate, or how a species grain will finish once sanded and oiled. When you’re uncertain, it helps to draw on our teams knowledge. We can guide you through species selection, moisture content, durability, and matching boards or off-cuts, so you can choose with confidence and make the most of your timber.
Selecting Timber Boards & Off-cuts Key Take-aways
Selecting timber well is about balancing purpose, quality, cost, and character. Boards and off-cuts from Scottish Wood offer great options but you get the best result when you think ahead: what your project needs now, and how the timber will behave. Plan ahead, inspect well, leave a little margin, and your result will look sharper, last longer, and give you satisfaction.
