== == Since each of the log rules was developed using different methods with different assumptions, it is logical that they will not always result in the same volumes for given size logs. Table 1 shows a comparison of the three log rules for 16-foot logs ranging in diameter from 6 to 40 inches. Compared to the International Rule, both the Scribner and Doyle Rules underscale logs of smaller diameters. For example, a 12-inch-diameter log contains 95 board feet on the International scale, 80 board feet on the Scribner scale, and 64 board feet on the Doyle scale. Overall, the Doyle Rule will result in lower log volumes than the International Rule, up to a log diameter of 30 inches. Since nearly all logs in Virginia are below 30 inches in diameter, for all practical purposes the Doyle Rule will underestimate the actual board footage. If you are selling stumpage or logs, it is important to recognize the differences in volume associated with the different log rules. Since stumpage or log prices are based on the timber or log volume, you will receive substantially more income with the rules that scale your sizes higher. For example, take a log of 16 inches diameter x 16 feet in length and a value of $100 per thousand board feet. This log would have the following volumes and values based upon the different log rules: {| ! Log
Diameter
(in.) ! Log Rule ! Volume
(board feet) ! Value ($) | 16 International 180 18.00 16 Scribner Decimal C 160 16.00 16 Doyle 144 14.40 |}

A 2X6 (dry Douglas fir) weighs 2lbs per foot. Thus a 20ft 2X6 would weigh 40 lbs. Other types of lumber such as pine weighs more and all lumber is heaver when wet or if it has been treated.

There are lots of driftwood on this river, wonder if there's a lumber yard somewhere near.

Nominal Dimension Lumber is what it's cut to and Net dimensional Lumber is what it actually is.
Wood is a hard substance, composing of the stem of branches of a tree of shrub. Lumber is wood- which has been conditioned
Seasoned lumber has been dried, usually in a lumber kiln, to roughly 6% to 8% moisture content. Unseasoned lumber may be anything from dripping-wet-fresh-from-the-tree to air dried, depending on how long it's been sitting at the lumberyard and on the local humidity.
Paralam is manufactured by Weyerhauser and Versalam is manufactured by Boise-Cascade. Other than that, there really is no difference.
In Canadian lumber mills at least, chipboard is made with smaller particles than fibreboard.
birch should be lighter.
This refers to the amount of aging it has had since cut. Green is another name for unseasoned wood. This refers to firewood and cut lumber. Seasoned is ready for sale in a lumber yard or fireplace ready.
Re sawn lumber is achieved by re-processing smooth standard milled lumber to achieve a roughened surface, normally for aesthetics. The lumber is passed along a saw blade to achieve the desired effect. The finished size is smaller than nominal call-out dimension. Rough sawn lumber is the board, plank or timber prior to milling for final sizing. Rough sawn lumber is larger in dimensions to the nominal call out. Rough sawn lumber is sometimes referred as rough milled lumber when certain exact sizes are desired.
It's a measuring tape used to measure lumber etc by carpenters, etc. usually spooled in some kind of case with a belt clip. Common at hardware stores.
If he went to Home Depot; he could buy a brand new piece of lumber and cut that. However, he will need to get a piece of lumber measuring 5 feet 1/4 inch in lnegth if he is using a skill saw that has a blade measuring 1/8th of an inch thick. Four cuts will eat away 1/4 inch of lumber leaving him with five pieces of wood measuring 1 foot in length.
