What is billet sawn?
Sawn Billet
Logs are cut apart with a saw but still cut with the grain as much as possible. Grading is off the edge grain. Sawn material can cross the fiber therefore altering the tangential slope even with straight edge grain.
What is ordinary sawing?
Ordinary Sawn or Through Sawing: Parallel cuts made throughout the length of the log. Cutting parallel slices of planks. Easiest and economical method. … Causing warp and twisting of planks.
What is radial sawing?
Radial sawing is a innovative sawmilling process specifically designed to maximise the recovery of wood from smaller logs. … As a result, the wood is more prone to bending, cupping or splitting. Radial sawing, in contrast, cuts the logs into wedges first, in line with the natural way a log would split on drying.
What is rift and quarter sawn?
Rift and Quartered Sawn
Logs are cut with the grains intersecting the face of the board at an approximate 60-degree angle. The log is sawn into four quarters and each quarter of the log is sawn perpendicular to the growth rings at an angle, therefore being named rift and quartered.
What is conversation timber?
Timber conversion is the process of turning a log into a pile of usable planks or boards. … It also expands and contracts less than other timber sawn using other methods. The plain method produces quarter sawn material that is close to the log’s center, creating a flame-shaped pattern.
What is live sawn?
Live Sawn is a European approach to cutting lumber. Plain sawn is the modern way of sawing lumber, in which the log is turned till the Sawyer can cut off the clearest board. In live sawn, the logs are sliced directly through without turning the log.

What is Rift wood?
Rift sawn lumber is typically narrow with a very straight grain pattern on the face of the board. Rift sawn lumber is usually used with oak to avoid the flecks that are common in the species. … Similar to quarter sawn lumber, rift sawn lumber is also referred to as radial grain.
What is the difference between rift sawn and plain sawn?
Due to the position of the growth rings in the cut, Quarter Sawn lumber is more dimensionally stable than Plain Sawn. It resists expansion and contraction on plank’s width. Rift Sawn lumber is the most elite of the cuts. … Rift Sawn lumber is the most dimensionally stable cut of lumber available.
