Choosing the Right Timber from British Woodlands

Why Homegrown Timber Deserves a Second Look

Walk into most timber yards and you will be offered pale, predictable boards that could have grown anywhere. British woodlands produce material every bit as good, and often far more interesting, provided you choose it with a little care. The catch is that homegrown timber is not one product but dozens. A plank of wych elm from a Devon hedge bank behaves nothing like a length of homegrown spruce. Get to grips with species, grain and moisture content, and a stack of rough-sawn boards becomes something you can build with real confidence — and enjoy for decades.

Getting to Know the Species

Our native and long-established trees each have a personality, and matching that personality to the job is most of the battle.

• Oak — the workhorse. Strong, durable and beautiful, but rich in tannins that react with iron, staining the wood blue-black around fixings. Use stainless or hot-dipped galvanised screws. Cut away sapwood on anything destined for outdoors; it is not durable and woodworm adores it.
• Ash — tough, springy and superb for steam bending. Excellent for tool handles, chair parts and ladder rungs, though it rots readily outdoors unless well protected.
• Sweet chestnut — coppices freely and makes outstanding fence posts, rails and cladding. Outdoors it is often a straight swap for oak at a fraction of the cost.
• Sycamore — pale, close-grained and food-safe, traditionally used for butchers' blocks and kitchen surfaces. It turns and carves beautifully.
• Beech — hard, dense and ideal for workbench tops, mallets and drawer sides, though it moves noticeably as humidity changes.
• Elm — its interlocking grain makes it almost impossible to split, which is why it was the traditional choice for chair seats and cart hubs. More available again as regrowth matures.
• Alder — unglamorous but superb in permanently wet ground, from sluice gates to piles, and pleasant to carve.
• Hazel — the coppice staple. Hurdles, wattle panels, bean poles and pea sticks, all from stools cut on a seven-to-ten-year rotation.
• Yew — dense, elastic and knotty. Small dimensions only, but unmatched for bows, decorative turning and inlay.

Reading the Grain Before You Cut

How a board is sawn from the log matters more than most beginners expect. Through-and-through boards — also called plain or flat sawn — show that broad cathedral arch figure and give you the widest usable widths, but they cup and twist as they dry. Quarter-sawn boards are cut radially, giving straighter grain, far greater stability and, in oak, those silvery ray flecks along the face. For a table top that must stay flat or a door that must not bind, quarter-sawn stock is worth hunting down. Learn to spot shakes, the splits that run along the grain, and oversized knots; both weaken a board and dictate where your joints can safely fall.

Seasoning: The Patient Art

Green timber is heavy with water, and it will move as that water leaves. Traditional felling in winter, when sap is low, reduces staining and insect attack, and it is still sound practice. After milling, stack your boards flat with stickers — thin battens — between each layer so air can circulate, weight the top of the stack, and shelter it from rain while keeping the sides open to the breeze. The old rule of thumb holds up well: one year of air-drying for every 25 mm of thickness, plus a year. A 50 mm oak board therefore wants roughly three years before it is ready for interior work.

You are aiming for a moisture content of around 8–12 per cent for furniture that will live indoors, and 12–15 per cent for external joinery. A cheap moisture meter is the single most useful purchase you will make. Kiln drying is faster, but it can case-harden timber, leaving a dry shell around a wet core that will surprise you later.

Matching Timber to the Job

For small-scale furniture, stability and figure usually matter most: quarter-sawn oak or ash for frames and legs, sycamore or lime for drawer bottoms and carved detail, beech for anything that takes a beating. For building work, think durability and movement. Oak and sweet chestnut for exposed frames and cladding, larch or Douglas fir where you want something lighter and more economical, alder or elm below the waterline.

Remember, too, that homegrown timber is often sold waney-edged and ungraded, so buy a little more than you need and allow for trimming. Selecting your own boards, rather than accepting a shrink-wrapped bundle, is half the pleasure.

Working Green, and a Word on Waste

Some of the finest British work is done in green wood rather than seasoned stock. Green oak framing relies on draw-bored mortise and tenon joints, pinned so tightly that the timber shrinks onto the peg and tightens as it dries. Windsor chairmakers turn legs green and let them shrink into the seat. Both traditions turn moisture movement from a problem into an advantage.

Finally, waste less. Offcuts become pegs, wedges, handles and kindling; shavings go on the compost or the chicken shed; bark mulches the beds. A well-managed wood, cut selectively and replanted, will keep supplying you with beautiful material indefinitely — provided you respect the grain, the species and the slow business of drying it properly.
