Log Volume Tables. Pocket and A5 size log volume ready reckoner for calculating the volume of logs based on centre diameter and log length; Tables of log volume in cubic metres from lengths between and 15m in m increments and diameters between 15cm and cm; Spiral bound for ease of use; Pocket size is 11cm x 15cm, A5 size is cm x 21cm.

(timber volume plus air spaces) to timber volume (volume of timber only). A commonly used factor is although this can vary between and However, if you want to get more accu - rate results then you can calculate your own, stack-specific conversion factor.

Example: Using a factor, the volume of timber can be calculated asFile Size: KB. Instructions: Log Volume Calculator Diameter: All the major log rules use the small end diameter, inside the bark, as the basic size measurement.

If the log is not perfectly round, then two readings are taken at 90 degrees to each other and averaged. Length: The log length is the length to the last full foot (especially for hardwood logs).

C. Tree Volume Measurement. The sawlog volume of the tree may be found by referring to the table on the “Tree Scale” side of the stick. If, for example, the tree is 16 inches in diameter and contains three foot logs, the volume ( board feet) will be found under the inch volume on the 3.

Volume tables can be created for total cubic volume, merchantable cubic volume, Scribner board foot volume, and/or International 1/4-inch board foot volume, depending upon the volume equation selected.

For example, if the log is 14 inches in diameter and 16 feet long, the volume is board feet. The log volumes used on the stick are those of the international 1/4-inch log rule.

This rule gives the most accurate measurement of board-foot. • Log Measurements can be: – Measuring diameter inside bark, including one bark, two bark, rounding to the nearest inch, dropping the fractional inch, diameter the narrow or averaging the diameters. – Measuring length including or excluding trim • Split length over 20 or 40 feet • Longest length on top or bottom – Defect deductionFile Size: KB.

Chapter 2. Measurement of Logs Logs are tree sections that are to be converted to products such as lumber, veneer, and plywood. Many log measurement systems have been devel-oped and can be very confusing. In this chapter, a number of important domestic and foreign log measurement systems, often called log scales or log rules, are described File Size: KB.

Scalers measure logs in a consistent man-ner, using standardized volume tables and log rules. Log sellers, purchasers, and log scaling and grading bureaus employ scalers.

Including bark thickness in the log diameter measurement will increase the form class for any tree and consequently the volume read from the table. Form class averages. Advance knowledge of the form class of common eastern species will be helpful to cruisers unfamiliar with this term (table 4).

Measuring wood is part science, part art; you use many different units, you face many potential problems. The below quote from Converting Factors for Southern Pine Products, Williams and Hopkins, USDA, illustrates how confusing measuring and converting wood volumes can be.

Foresters now mainly use metric measurements and a vast array of tables allow calculations of usable timber volume from measurements of standing individual trees and whole stands (where these comprise relatively uniformly-sized trees), as well as felled Size: KB.

To use this rule to calculate the volume of piece of timber of rectangular section, set one side in inches on E and the other side in inches on C. The volume in cubic feet is found on B against the length in feet on A.

A LANDOWNER'S GUIDE: MEASURING FARM TIMBER ISSUED: REVISED: D.H. Graves The volume of timber products in the farm woodland is often an unknown quantity, yet it is of great importance for inventory, management plans, investment evaluation and timber sales.

Units of Measure All products are measured by some unit. To use the scale, first measure the average diameter of the small end of the log inside the bark (in inches). Locate that row on the scale. Next, measure the length of the log (in feet). Move over on the scale to that length column.

Where those two measurements intersect, you will. Wood fuel measuring – Guide book 5 5 Measuring woodfuel with scales Application Measuring woodfuel with scales is a reliable method to estimate the ‘green’ weight and volume (including bark) of small-diameter thinnings destined woodfuel, logging residues and stumps.

The. A Volume table is a chart to aid in the estimation of standing timber volume. These tables are based on volume equations and use correlations between certain aspects of a tree to estimate the volume to a degree of certainty. The diameter at breast height (DBH) and the merchantable height are used to determine the total volume.

Harvesting Timber and Timber Taxes All timber harvested in Oregon is subject to the Forest Products Harvest Tax.

In addition, harvests may be subject to the Small Tract Forestland (STF) severance tax. Understanding Oregon’s Timber Tax Programs and How to Complete Forms Forests contain one of Oregon’s most valuable natural resources—trees.

If both buyer and seller are aware of this and if price is adjusted accordingly (Table 1), any log rule may be used because the total value of the timber (price multiplied by quantity) will remain the same (Figure 2).Author: Robert Bardon.
