Scaling operations in Australia

John Ellis, Group Technical Manager, C3 Ltd.; and Managing Director of Scaling Research International, Mount Maunganui,
New Zealand

John explained the geography of the “green triangle” of southeast Australia and showed a video on the scaling process used in Australia  Unlike many other regions, staff are trained in processing, skidding, loading and scaling logs. Scaler turnover is 20% per year, which is an improvement over New Zealand operations, although something that they would like to improve upon. John went on to cover how checking and training are carried out. John also covered some of the issues and operations in New Zealand for comparison

Statistical sampling issues

Kim Iles, Kim Iles and Associates, Nanaimo, British Columbia

Kim presented a critical review of some of the self imposed limitations that are holding us back as measurements professionals. For example: why we continue to round volumes despite the fact that we are virtually all using electronic means of calculation; why we assess gross volumes, subtract defect to determine net volume and then only keep the net figures when the gross can be very useful.  We should be able to collect more basic data and manipulate it as needed. It is time to stop using Scribner. We need to stop providing rules for making estimates which do not reflect reality.  Finally, we need to recognize that we are in the measurement business, not scaling business.

Scaler training course: combination of online and practical coursework to train log scalers

Michael Weller, Northern Idaho College, Coeur d’Alene

Mike stated that one quarter of manufacturing jobs in northern Idaho are in wood products and are forecasted to increase in the next 10 years. The need for scalers is particularly critical. Scaler training can be very costly and often companies do not have the capacity for intensive training so a need and economies of scale afforded by utilizing the college were requested. The program was initiated with support from 3 mills for 2 years to train students for three jobs: log scaler, industrial control technician, and saw filers.  The mills provide a train-the-trainer course and support to develop training plans. There is a high degree of commitment from industry.  On-line learning is new for trainers and students; also how to train adults is an issue.

Management of log manufacturing quality

Jerry Youmans, Potlatch Corporation, Moscow, Idaho

Jerry covered the approach at Potlatch to maximize value not volume.  They have 700,000 acres in Idaho and are currently delivering logs to 19 locations. Their procedures include: no harvesting without a customer order; manufacture the log as best possible and avoid mis-sorted logs. They have annual training for their harvest contractors, on-site inspections and regularly inspect logs in their customer's log yards weekly. Contractors are familiarized with what the customer wants and foresters go over this with each contractor, looking at preferred lengths, acceptable lengths and also unacceptable lengths. They can have up to 7 different customers per harvest area. Jerry shared a training video (click here to view) that Potlatch uses to help inform logging contractors of what they expect.

April 11, 2011

On April 11, the group visited the Potlatch compound in St. Maries, Idaho. There was a mill tour in the plywood plant and a rollout of logs to scale in the log yard. Potlatch provided lunch and a well organized field day for the group. The logs for the rollout were particularly challenging because they had been in inventory for quite some time, so it was difficult to determine the extent of the heart checks (as seasoning exaggerated their size) and ignore the effects of the surface checking that occurred in inventory. The agreed upon school-book answer was (Scribner short log): gross volume = 21,520: net volume = 19,040. Many thanks to Potlatch for the excellent hospitality.
