Douglas Fir Regarded as one of the strongest and most durable soft wood materials, Douglas Fir has always been the preferred choice of builders, engineers and architects. Popular for its light rosy color, excellent strength-to-weight ratio and for being dimensionally stable, it's able to provide superior nail-holding capabilities.

I find that trees and lumber are like air. Finding a person willing to pay cash money for breathing, a log or lumber is rare. Fresh air and pretty lumber is a treasure even if cash is not part of the picture. Sorry for getting philosophical. You would get $/mbf less logging costs at my mill.

Pricing/Availability: White fir is used as construction lumber and is commonly grouped together with other species of fir and hemlock and sold under the more generic label “HEM-FIR.” Prices should be moderate for such utility lumber, though clear, quartersawn, or other such specialty cuts of fir lumber are likely to be more expensive.
Strength and related properties of white fir (Abiesconcolor) were reeval-uated by combining previous data with that developed from recent samples ob-tained from Jackson and Lake Counties, Oregon, and Calaveras and Plumas Coun-ties, California.
New average strength values compare favorably to the previ-ous averages for the species, although. Hem-Fir is a species combination of Western Hemlock and the true firs (Noble, California Red, Grand, Pacific Silver and White fir).With strength properties slightly below Douglas Fir-Larch, this is an extremely versatile species group and useful.
White Fir. California White Fir is one of the most versatile soft woods in America. It is non-resinous, fine textured, mills accurately, and remains straight.
White Fir is widely used in residential and light commercial construction. Facts about White Fir. Let’s say you estimate the volume of your stand of mature White Oak to eq board feet.
One estimate of its value can be found by multiplying the mean reported for no. 1 common White Oak ( for Spring of and in the Fall) by 10 (10, board feet divided by 1,). So you’re White Oak is likely worth about $4, Sherwood Lumber Executive & Management Promotions.

The National Grading Rule establishes the lumber classifica-tions and grade names for visually stress-graded dimension lumber (Table 6–2) and also provides for the grading of dimension lumber by a combination of machine and visual methods.
Visual requirements for this type of lumber are developed by the respective rules-writing agencies forFile Size: KB. J&W Lumber specializes in Rough Douglas Fir from small 2×2’s to 12×12 timbers and larger, available in lengths exceeding 30 feet.
As one of the most common species in American forests, Douglas Fir is strong and its tight know pattern, Premium Douglas fir is a beautiful wood to use exposed.
Lumber Design Values. Design values provided herein are for Western softwood species manufactured and shipped by mills in the 12 contiguous Western states and Alaska.
Except as otherwise noted, the values are computed in accordance with ASTM standards based on clear-wood tests or on tests of full-size pieces in specific grades. The assigned design values for Hem-Fir apply to this grouping. Since Hem-Fir lumber is fine-textured, straight grained, stiff, and easily worked, it adapts itself readily to many uses.
It is particularly distinguished by its strength, freedom from splintering, and its ease in working. White Fir White Fir lumber and lumber products have long. all log diameters, while the Doyle Rule underestimates the true yield of lumber for smaller logs.
The actual yield of lumber from a scaled log will vary with mill technology, wood species and other factors. Log Diameter (inches) 10 15 20 25 30 Predicted Lumber Yield (percent) 40 50 60 70 80 90 D o y l e S c a l e International 1/4" Rule OverrunFile Size: 1MB.
The table below provides laboratory values for several properties of wood that are associated with wood strength. Note that due to inadequacies of samples, these values may not necessarily represent average SpeciesAverage Specific Gravity, Oven Dry SampleStatic Bending Modulus of Elasticity (E)Impact Bending, Height of Drop Causing FailureCompress.
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).
In spruce-pine-fir, No. 1/No. 2 2x10 or 2x12 would do the job. Figure 4 After determining what size lumber to use, turn to the tables in Design Values For Joists and Rafters to select a species and grade that meets the required Fb and E values.
The tables shown here are excerpts from the hem-fir, Douglas fir-larch, and spruce-pine-fir tables. a log builder friend of mine told me he`s left his cabin for several days in cold ing to find it still slightly warm when the fire was out whole is the reason the log builders requested the tests because they found they weren`t getting what was cordwood owners report that some times in the winter their furnaces.

For many years, the design values of Canadian dimension lumber were determined by testing small clear samples. Although this approach had worked well in the past, there were some indications that it did not always provide an accurate reflection of how a full-sized member would behave in service.
Beginning in the s, new data was gathered on full-size graded .grade 2, and a grade 2 butt log is usually topped by a grade 3 log, The consistency of this 1, 2, 3 order of log occurrence is demonstrated in table 2, for PO5 trees.
The particular value of this system is that it permitted the use of lumber-grade yield data by log grades in building up grade yield and value data for the tree by: 1.Recovery information is presented by diameter and log grade for lumber volume, lumber grade, and lumber and log value.
