Sitka Spruce is light weight but has a high strength ratio. Most common uses for Sitka Spruce is in furniture, millwork, aircraft frames, musical instrument, boat building, or virtually any application where a wood material with a good strength-to-weight ratio is needed CVG - Clear Vertical Grain CVG Sitka Spruce. 4/4 Full rough milled to 15/ American Sitka Spruce Wood Categories: Wood and Natural Products; Wood; Softwood. Material Notes: Softwood. Relatively easy to work with hand tools. Data is based on small, clear, air-dried samples unless specified. Usual surface texture: Coarse.
Sitka spruce is kind of uncommon in the Midwest. It's fairly common in the Pacific Northwest. The wood is light, 27 lbs/cubic foot (compared with 44 lbs/cubic foot for red oak). It's pretty soft too, with a Janka hardness of lbf (compared with 1, lbf for red oak). That means its about 61% as heavy as red oak, and less than half has hard. Detailed radial measurements of wood properties at four heights (0, , 5, and 20 m) were taken from year-old Pinus radiata D. Don growing at four final crop stockings (, , , and stemsha –1).Using these measurements, the objectives of the study were to examine pith-to-bark trends at several heights to (i) determine how stocking influenced modulus of elasticity (MoE), wood.
The effects of early re-spacing on the physical and mechanical properties of Sitka spruce (Picea sitchensis [Bong.]Carr.) structural-dimensioned timber were studied using material from a fully replicated year-old trial located in Northern Ireland, which had been thinned at age 11 years. Value and workability are what you'll find in Sitka Spruce. Some large sound knots are present. Every knot has fiddleback around it and checks are present in the knots. Clear epoxy fills these well. These slabs are kiln dried, surfaced on two sides, and ready to use for your woodworking projects! This slab has numerous large knots with checks.

The orthogonal cutting of wood from fast-grown sitka spruce. Author: Hyde, Trevor James. ISNI: Awarding Body: University of Ulster Current Institution: Ulster University Date of Award: Availability of Full Text. Sitka Spruce from Southeast Alaska is the finest in the world, which is why many wood processors look for their supply of Sitka Spruce from Southern Southeast Alaska.
Prince of Wales Island, the place we call home, has the highest concentration of the best grade Sitka Spruce. The climate here is maritime, cool but moderate. The color of Sitka spruce wood ranges from nearly white to pink to light brown, and sometimes has a candy-stripe look.
Heartwood tends to run slightly darker. Very straight-grained, Sitka spruce has less conspicuous growth rings than pine. It's also about 10 percent lighter, weighing 25.
Introduction. Sitka spruce (Picea sitchensis [Bong.]Carr.) is the most commonly planted commercial tree species in the UK (Forestry Commission, ), where it is grown on a rotation of ∼40 years.A breeding programme for Sitka spruce has existed in the UK since the s, with the primary focus on improving the growth rate, stem form and branching characteristics (Fletcher and Faulkner, Cited by: 7.
Variation of radial wood properties from genetically improved Sitka spruce growing in the UK Article (PDF Available) in Forestry 89(2) November with Reads How we measure 'reads'. Quartersawn billets of instrument-grade Sitka Spruce can easily exceed the cost of most all domestic hardwoods in terms of per board-foot cost.
Sustainability: This wood species is not listed in the CITES Appendices, and is reported by the IUCN as being a species of least concern. Sitka spruce pitch was also used as a medicine for gonorrhea, syphilis, internal swelling, and toothaches (Pojar & MacKinnon ).
A decoction of the roots has been used in the treatment of diarrhea. Economic: Sitka spruce produces high-grade lumber that is the most important wood for airplane and glider construction. In World War II, this.
The need to produce good quality sawn timber has been recognized by Sitka spruce tree breeders whose main objective has been ‘to develop breeding populations well adapted to a range of site types, with improved stem form and growth potential and wood qualities satisfactory for the sawn timber market’ (Fletcher and Faulkner, ).
The UK's. SITKA SPRUCE WOOD Sitka Spruce is the musical instrument industry’s standard for stringed instrument tops. Characteristics of Sitka Spruce Origin of Wood Type USA & Canada Botanical Name Picea sitchensis Specific Gravity Avg. Weight Per BF lb/ bf. The use of Sitka Spruce for all components in the aircraft is most likely a result of its demand in the wing spar.
Construction becomes easier if only one type of wood is required and the smaller components can be made from the scrap. That's why Sitka is used for turtle. The wood has excellent acoustic properties and is used to make sounding boards in pianos and other musical instruments such as violins and guitars.
In North America, structural grades are in accordance with National Lumber Grades Authority (NLGA) rules for dimension lumber. Sitka spruce is currently marketed under the Northern Species group. Assumptions made in calculating the amount juvenile wood Sitka spruce stems. Weak wood: Fast grown trees make problem lumber of plant spacing and cutting age to estimate the dry mass of.

It is the largest spruce in the world with a trunk volume of m³ (11, cubic feet) and an estimate age of years. Status. Ooop. The email you entered isn't valid. WooHoo. You subscribed successfully. You're unsubscribed.
Alaska Specialty Woods Inc. has emerged as a world class, custom shop soundboard producer. We are also the largest producer in the world that uses % salvage sourced old growth Sitka Spruce timber that is procured locally. We are also the largest soundboard producer in the state of Alaska.
Aged wood has long been regarded as a premium wood fiber. We try to sell spruce from sources who are engaged in selective cutting or are salvaging downed or standing-dead trees. Sitka Spruce Wood. Sitka spruce is a softwood with an average specific gravity of, oven dry. With its relatively low weight and high strength, Sitka spruce was and is highly valued in the manufature of small airplanes.
Sitka Spruce Lumber. Sitka Spruce has an outstanding stiffness-to-weight ratio, and is available in large, vertical-grained pieces, lending this timber to a wide range of uses - like the hand carved bench at our head office made by Haida Gwaii artisans.We sell beautiful antique and reclaimed Sitka Spruce lumber.
Our Sitka Spruce wood comes in custom widths and lengths and %. See why E.T. Moore is the best in Sitka Spruce and supplies.AbstractThe objective of this study was to understand better the cutting forces and chip formation of Scots pine (Pinus sylvestris L.) with different moisture contents (MCs) and machined in different cutting directions.
To that end, an orthogonal cutting experiment was designed, in which Scots pine was intermittently machined using a tungsten carbide tool to produce chips.
