  • Measure felled logs or loads of pulpwood to calculate volume, weight, dimensions, and marketable value, using measuring devices and conversion tables.
  • Measure log lengths and mark boles for bucking into logs, according to specifications.
  • Identify logs of substandard or special grade so that they can be returned to shippers, regraded, recut, or transferred for other processing.
  • Jab logs with metal ends of scale sticks, and inspect logs to ascertain characteristics or defects such as water damage, splits, knots, broken ends, rotten areas, twists, and curves.
