A
Air Dried Wood
Lumber or hardwoods that have been either dried by exposure to natural atmospheric conditions outdoors or in an unheated shed or died to equilibrium with the surrounding atmosphere. Moisture content of air-dried wood fiber depends on relative humidity, temperature, and length of drying period. Also referred to as air seasoned and contrasts with kiln-dried lumber.
B
Board Foot
Unit of measurement represented by a 1”thick x12” wide x12” long piece of lumber. The number of board feet in a log we use is estimated with the Doyle Log Scale.The actual yield of a log after sawn into lumber is often greater than the estimated yield. Both logs and lumber are sold by board foot
D
Defect
A crook, decay, split, or other injury that decreases the amount of usable wood that can be obtained from a log.
G
Grade
The quality rating given to wood products.
Green Wood
Used to describe wood that is freshly sawed or wood that has received no intentional drying. Softwood lumber with a moisture content above 19% is considered green.
H
Hardwood
A term used to describe broadleaf (usually deciduous) trees, for example: oaks, maples, ashes, cherry, walnut and elms are hardwoods.
J
Joiner
A machine to square edges for processing
K
Kiln Dried Wood
The process of drying wood in a kiln. We use an iDry Vacuum Kiln.
L
Live Edge
The natural edge left on one or two sides of a piece of wood.
Lumber
Wood that has been processed to dimensional lumber standards
P
Porosity
The intensity or density of pores in hardwood.
Planer
A machine that uses rotating knives to produce a smooth wood surface.
S
Softwood
Generally one of the botanical groups of trees that have no vessels and in most cases, needlelike or scale-like leaves. Examples include evergreen trees, conifers, cone-bearing trees or wood cut from these trees.
V
Vacuum Kiln
A vacuum sealed temperature, humidity controlled chamber using both heat and moisture to control the quality of wood produced.
This kiln uses airflow to dry a stickered pile similar to a DH kiln or conventional kiln but under a vacuum pressure similar to that on top of Mt Everest, making this a fast and nice drying system.
Specifications
Capacity: up to 4000 board feet
Stickered Lumber Pile:
16.5ft L x 60in W x 65in T

Wood Species
Group of similar individuals having a number of correlated characteristics and sharing a common gene pool. The species is the basic unit of taxonomy on which the binomial system has been established. The scientific name of a plant or animal gives the genus first and then the species as in Abies (genus) grandis (species). Species is both the singular and plural form of the word.
Wood Moisture Content (MC)
The amount of the water within a piece of lumber measured as a percentage of the weight of the dry wood. Wood absorbs or gives off moisture depending on the ambient moisture in the air. A living tree has a moisture content of 75% or higher. Moisture content varies based on many factors such as the species of wood. In order to kiln dry certain hardwoods, a 25% moisture content is required.
