T3.1 · DefineQuarter-sawn timber is cut so that the growth rings run at a steep angle, close to 90°, to the wide face of the board. Back-sawn timber has the rings roughly parallel to the face, and live sawing cuts straight through the log, giving a mix.T3.2 · StableBecause the rings run through the thickness, quarter-sawn boards shrink and swell much less in width and are far less likely to cup or warp. This keeps table tops, panels and joints flat and tight.T3.3 · Figure + wearQuarter sawing exposes the medullary rays, giving an attractive ray figure on species such as silky oak, and the edge-grain surface wears more evenly.T3.4 · Trade-offThe trade-off is that quarter sawing is slower and wastes more of the log, so the boards cost more. That is why it is chosen for fine furniture, where stability and appearance justify the price.
