Rough (unsurfaced) Lumber, kiln-dried (DHK) 6-9% MC
or air-dried to
9-15% MC
(moisture content), from slow-growth
logs in NE Iowa and NW Illinois. One of the world’s best growing areas for Black Walnut Timber.
Sold by the board foot
(BF) except for 3/4 Lumber which is sold by the Square Foot (SF). Need help converting to/from Board Feet (BF) to
Square Feet (SF) or Square Inches (SI)? please see Conversion Aids

Grades FAS and below
are standard NHLA grades - Grades above FAS are not standard
Note (1) to reduce
yield loss during milling processes such as snipe in planning, jointing, or
straight line ripping - End or Edge defects may be present in the
board but are excluded from the width/length consideration
* - If the
"UPS-Ground max 59" boards shipping method is selected ...
the minimum
72" length is waved but Yield% and other rules still apply.
If no boards 59"
or less are available for the grade and options specified, or if minimum lengths
of 6' or more are specified, boards will be crosscut to comply with the
shipping method limitations
Surfacing:
.
In
Finish Planning we pay attention to grain, make multiple passes, and use slow feed
rates. Our objective is not to maximize production rates, instead our objective is to maximize heartwood, and minimize defects,
sapwood, and tear out. An added benefit is that the time required for
finish sanding is reduced. The charge doesn't begin to cover the labor cost.
No
longer offered - Production Planning, which most retailers do, emphasizes economy by maximizing production rates.
Deeper cuts and higher feed rates result in fewer passes and more tear out.
It seemes a shame to us to do this walnut lumber so we stopped offering as
an option.
Minimum
Width: This option
cannot be used for Selects since, with only rare exceptions, a Select is a
board that grades F1F but is less then 5" wide. Also it is a waste of
money to specify a minimum width equal to the minimum width required in
the Grade rules.
Minimum
Length: If the
"Boards less then 59" UPS shipping method is selected and if minimum lengths
of 6' or more are specified, boards will be crosscut to comply with the
shipping method limitations. Again, it is a waste of
money to specify a minimum length equal to or less than the minimum length required in
the Grade rules. May
not be used in conjunction with Maximum Length.
Maximum
Length: Read
carefully please, this option is often misunderstood! Be sure to
include your maximum length specification in the "Comments".
Boards shipped will be equal to or less than the length you
specify. You are in effect instructing us to Crosscut at the length
you specify - the resulting board cut off will be included in your
shipment and will count towards the order total. Do not use this
option if you are simply trying to advise us as to your preference on where
to make crosscuts because of ground shipping girth limitations. May
not be used in conjunction with Minimum Length.
Sawn:
Most of our Lumber is plain sawn.
Rift/Quarter
Sawn option: Per NHLA Rules Quarter Sawn is defined as "When
80% of the surface....shows the radial grain at an angle of 45 degrees or
less with one face" For 5/4 and less stock, rift or quarter sawn boards
are happenstance, not by design, so we have very little of this stock.
Having "learned" from past experience we will not allow any
attempt to further refine, define, or otherwise control grain or growth ring
(radial grain) orientation beyond this general option We supply instrument
"builders" and "steam benders" who are artists in their
own right so we are aware of their unique needs - but those needs are beyond
the scope of this option and should be handled by quotation.
Center
Cuts: 6/4 and thicker lumber inventory includes boards cut from
the center of the log. Center Cuts contain Pith (boxed and
showing), and are more prone to checking and splitting, but they also tend to be rift or quarter sawn. In fact, I extract
cuttings from Center Cut lumber to meet the unique needs of the artists
mentioned in the Rift/Quarter Sawn option. The grade is determined
without regard to boxed Pith. Center Cuts may be included in the #2&3
Common mix unless you specify
differently.
Drying:
This web site is full of discourse about our Air-dried lumber so maybe the
only further explanation is the reason for the variance of 9% to 15% MC which is
quite simply due to the relative humidity fluctuations in our Northern
Climate and the effects of solar heating at the warehouse. Lumber
pulled from the top of the 12' high stacks is dryer than lumber closer to
the ground.
DHK:
short for Dehumidification Kiln. Our Dehumidification Kiln uses low
temperature dehumidification drying - never over 120 degrees (except for 2
hours at 145 degrees to kill bugs) - this slow drying is to avoid the
internal stresses in the boards so common with the big, fast Kilns used in
the industry; therefore the drying process will be slow and we may have inventory
"availability" issues. But, to my knowledge, we will be the
only source for DHK Dried, Unsteamed Walnut Lumber on the www and will have
superior milling qualities to boot. As time permits we will
construct a web page about our Kiln. Kiln Dried Lumber is stored in a
climate controlled area (8%-9% MC)
Order
Quantity has a direct effect upon length of boards shipped.
Affected are lumber orders with weights less than 30 lbs. (less than
9 BF of Rough Lumber). The limitation is UPS OS1 (Oversize 1)
classification. Due to UPS shipping limitations we may need to crosscut boards.
We reserve the right to crosscut as we deem appropriate. You may use the product “Comments” section on your order for instructions if you have a particular need. UPS
also has a girth (( 2 (w + h) +L)) limitation For
more details or, To
override limitations and receive longer boards Please see
[UPS Limitations] .
