With lumber a board foot is calculated by: multiplying THICKNES X WIDTH X LENGTH divided by 144 = BOARD FEET (THICKNESS, WIDTH & LENGTH measurements are in inches) |
|
DOYLE LOG RULE for estimating board feet in a log |
|
Length of log in feet |
|
Length of lumber in feet |
|
LUMBER SCALE for calculating board feet in lumber |
|
*The DOYLE LOG RULE is a rough estimate of the board feet that a log may yield.
Bandsaw mills are able to recover many more board feet per log due to the thin blade profile that removes less waste in the form of sawdust.
Other factors that effect the actual board feet a log will produce:
Branches or Limbs along the length of the log Rotten spots or hollow logs Foreign material imbedded in the log Size of lumber the customer desires from the log |
