Softwood is a product of cone-bearing trees. Pine Ponderosa Pine is a very large pine tree of variable habit native to western North America, but widespread throughout the temperate world. This softwood is known for its rustic, knotty appearance and is commonly seen in warm cabins in both the Sierra Nevada and Rocky Mountains. Softwood is a product of cone-bearing trees.

Chapter 10 - Utilisation
CHAPTER 10 - UTILISATION Ian Nicholas (Scion Although eucalypts have a reputation for being difficult to saw, they can be easily sawn if the basics are understood. Historically the sawing of large logs was seen as the best way to overcome stresses in the log. Preferred DBH targets were 75 cm, to yield several logs with an SED greater than 40 cm. New developments have seen successful sawing of small diameter logs into high quality products.

REPRINTED FROM CONCRETE OPENINGS | VOL. 23 | NUM.4 | DECEMBER 2014 CONCRETE CASES Contractor Revitalizes Famous New York Pier s part of a major redevelopment project on a pier in Lower Manhattan, New York, a concrete cutting contractor was given the Achallenge of coring 2,000 holes, flat sawing 22,000 linear feet and wire sawing 400 pier caps. The contractor’s work kept the overall demolition phase of the project on schedule and has helped to revitalize a famous landmark in New York City. The South Street Seaport is situated along the East River in Manhattan, close to the city’s financial district. The Seaport had a series of 19th-century commercial buildings that were linked to New York’s maritime heritage, but the cost associated with repairing and REPRINTED FROM CONCRETE OPENINGS | VOL. 23 | NUM.4 | DECEMBER 2014 CONCRETE CASES The pier deck was cut into sections using flat saws, some cuts being as deep as 18 inches. providing ongoing maintenance for the Seaport had begun to seriously impact the city’s budget—particularly after Hurricane Sandy caused severe damage to several structures in 2012. With the redevelopment of the Seaport’s main structure, Pier 17, underway, the search began to find a specialist concrete sawing and drilling contractor that could assist general contractor Trevcon Construction Co., Inc. with the demolition work. CSDA member Atlantic Concrete Cutting, Inc. of Mount Holly, New Jersey, was selected to do sawing and drilling work and help the general contractor remove the existing pier. -

Value Activation with Vertical Annual Rings – Material, Production, Products Dick Sandberg
Value Activation with vertical annual D Sandberg Value Activation with vertical annual rings – material, production, products Dick Sandberg TRITA-TRÄ R-98-36 ISSN 1104-2117 ISRN KTH/TRÄ/R--98/36--SE Value Activation with vertical annual rings – material, production, products by Dick U. W. Sandberg Stockholm Doctoral Thesis KTH-Royal Institute of Technology Dept of Manufacturing Systems 1998 Wood Technology and Processing SE-100 44 STOCKHOLM Abstract This thesis is a contribution to the R&D-program Value Activation at KTH- Trä. Two main aspects can be distinguished in the thesis. (i) A documentation and description of star-sawing technology from the initial idea to the first industrial plant. (ii) A description of research results within the fields of wood science and production technology, obtained during the development of the star-sawing technique. The two aspects are strongly linked to each other. The relation between ideas, scientific basis of the ideas and development results, the development of production technology and systems, and the dissemination of knowledge and technology transfer from all levels to the industrial implementation are described. The way in which all these development stages are connected in this work is also discussed. The thesis presents a new sawing technique developed at KTH, Div. of Wood Technology and Processing (KTH-Trä). The star-sawing concept, i.e. the sawing of the log according to the star-sawing pattern and the further refinement of the sawn product into PrimWood are described in detail. Experimental results are presented concerning different material properties of timber in general and of timber with vertical annual rings in particular.
