What is Quartersawn Wood?

define

There are a variety of ways that lumber can be cut out of a log including plainsawn, riftsawn and quartersawn. Each method has its own advantages and disadvantages.

Plainsawn wood is perhaps the most straightforward way to cut rectangular-profiled boards out of a round log. As shown in the drawing below, sawmills create plainsawn lumber by making a series of parallel cuts in a log. This system of cutting wood provides excellent yield because it minimizes scrap. Unfortunately, plainsawn lumber has some critical disadvantages. Woodgrain in a log is comprised of a series of concentric rings beginning in the center. Plainsawn boards have substantially different grain patterns depending on where they were cut out of the log. Since wood expands and contracts in different ways with respect to grain, plainsawn lumber is typically less stable than the alternatives listed below. The tendency of wood to expand and contract is called wood movement. Plainsawn wood often has interesting grain patterns (often called cathedrals) that are not created by other types of cutting.

plainsawn, riftsawn and quartersawn wood

Riftsawn lumber is much more stable than plainsawn lumber. As shown in the drawing, each board has the same relation to the log, and therefore each board will have the same grain pattern. Furniture made out of riftsawn wood has more of a uniform appearance due to the similarity of grain patterns among different boards. Unfortunately, rift-sawing provides very poor yield and as is evident in the drawing, lots of wedge-shaped scraps are produced. The low yield has ensured that riftsawn wood is a rarity at the lumber yard.

Quartersawn boards are created by first cutting a log into quarters and then creating a series of parallel cuts perpendicular to the tree's rings. The yield is not as substantial as in plainsawing but much greater than in riftsawing. The grain in quartersawn wood is relatively consistent, and therefore the end product is stable and often preferred by woodworkers and furniture-makers. Quartersawn wood may include medullary rays and wavy grain patterns that some people prefer to the figures that are revealed with alternative sawing methods.

Since the yield produced by quartersawing wood is substantially lower than other plainsawing, the cost is relatively high. Oak is the most common quartersawn wood; on occassion you may be also able to find quartersawn walnut, cherry and maple. The increased stability, makes quartersawn wood highly sought after for string instrument necks and fret boards. The neck of a guitar, bass or violin, for example, should remain stable throughout their lives; quartersawn wood helps ensure that instrument's sound remains as invariable as possible.

I think the definition of plainsawn wood is undisputed. But the definitions for quartersawn and riftsawn seem to be the subject of some dispute. I think that might be because in the 1930s someone came up with a superior method to cutting wood and that method was called quartersawn. But sometime after that, someone developed another, even better, method -- riftsawn. This wasted even more material but it produced a stronger plank of wood. But, since quartersawn had developed a meaning of superiority in the woodworking world, I think some people confused riftsawn and quartersawn, essentially giving the term quartersawn the properties of actual riftsawn. Regardless of the names ascribed, cutting wood in the manner labeled "riftsawn" above (i.e., where the grain is always perpendicular to the surface of the board) produced the strongest result even though it wastes the most material.

Although the properties of quartersawn wood make it highly desirable by furniture makers, in my opinion the "cathedrals" in plainsawn wood are very beautiful. I think its worth it for craftspeople to learn to deal with the wood-movement present in plainsawn wood.

I know some people who prefer the appearance of quartersawn wood, but I would guess that they are in the minority.
