Measuring as logs or planks
A-class branchless wood of joinery quality can be measured as a log before sawing and again after sawing. The true volume can be defined after sawing. When sawing with a buzz saw, the amount of sawdust varies between 10-15% of a solid measure. The amount is notably smaller when sawing with a bandsaw.
Calculation of volume of a plank
The calculation of a plank’s volume involves measuring its thickness, width and length, all of which are multiplied with each other.
The width can be measured:
A) from the middle of the face presented to the view or
B) by measuring the plank from both ends and counting the average of those figures.
When the width is known, the calculation of volume is performed as described above.
