May 2018
Read on to learn the five most common timber conversion methods, when using solid timber. This continues our series covering technical considerations when designing with materials, which our past clients and collaborators have found invaluable for their custom furniture projects.

Log conversions methods

1. Through and through 

through

This produces one or two boards of quarter sawn wood but the majority of the boards show contour markings; these boards are more susceptible to distortion.

 

2. Billet sawn

billet

A similar method for large diameter logs or where there is a large central shake in the heart of the tree

 

3. Plain sawn

plain

This boxes out the heart but does not provide a good yield of stable material.

 

4. Quarter sawn (traditional)

quarter

This enables all the boards to have the growth rings perpendicular to the face giving the most stable timber; it is rarely used by large commercial mills because it is time-consuming and wasteful.

 

5. Quarter sawn (modern)

modern

Two through and through cuts are first made to box out the heart of the tree, then the remainder is cut into narrow boards which yields a reasonable percentage of true quartered boards.
