  • Drill Bits 101 I've Used Dowels in a Variety of Woodworking Projects
    Drill Bits 101 I’ve used dowels in a variety of woodworking projects having bought myself a pretty decent doweling jig a few years ago. The jig itself came with a twist drill bit for each of the three dowel sizes. For my dowel joinery I often need to drill holes of two different depths; so sometimes it is handy to have two bits of the same diameter with stops set at the different depths. One day I inadvertently was using both a twist bit and a brad point bit and noticed very different results. For example, drilling into end grain was far more difficult with a brad point bit than with the twist bit. All of this got me wondering about the different types of woodworking drill bits. Hence my investigation into the family tree of woodworking drill bits. Note that many drill bits may be multi-purpose, but generally speaking there are different families of bits for plastic, metal(s), tile, and masonry, etc. The basic job of a drill bit of course is to stay centered and not wander, cut the wood to form a round hole, and eject the chips. Seems simple, but not so perhaps, which is why there are so many types of drill bits and even options on lips, lands, flutes, margins, and other design elements – details beyond the scope of Bevel Cut. Of all the types, the common twist drill, invented by Steven Morse in 1863 and covered in US Patent 38119 is the simplest. The V-angle of the tip can vary from 60 to 118 degrees, with the latter being most common in today’s hardware stores according to my own research.

  • Dalbergia Proposal Guatemala (Rev.2)
    CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA CONSIDERATION OF PROPOSALS FOR AMENDMENT OF APPENDICES I AND II A. Proposal Inclusion of the genus Dalbergia in CITES Appendix II with exception to the species included in Appendix I. The UNEP-WCMC assessed the Dalbergia species of Latin America and concluded: “… all populations of Dalbergia spp. from South and Central America appear to meet the criteria for listing in CITES Appendix II” (UNEP-WCMC, 2015). Including the whole genus in Appendix II will be essential for the control of international trade by eliminating the arduous task of enforcement and customs officers of differentiating between the hundreds of Dalbergia species listed and not listed in CITES. The inclusion will help ensure that legal trade does not become a direct cause of the extinction of these highly threatened species and will help curb illegal trade. Considering that CITES Appendix II must include all species, which although not necessarily now threatened with extinction may become so unless trade in specimens of such species is subject to strict regulation in order to avoid utilization incompatible with their survival, it is important to include the genus Dalbergia in CITES Appendix II. a) Resolution Conf. 9.24, Annex 2 a, Criterion A - ”It is known, or can be inferred or projected, that the regulation of trade in the species is necessary to avoid it becoming eligible for inclusion in Appendix I in the near future”. b) Resolution Conf. 9.24, Annex 2 a, Criterion B - ”It is known, or can be inferred or projected, that regulation of trade in the species is required to ensure that the harvest of specimens from the wild is not reducing the wild population to a level at which its survival might be threatened by continued harvesting or other influences”.

This document has been submitted by Canada, on behalf of Namibia and Canada as joint leads for the Standing Committee on the issue of Annotations.* Background 2. At the 17th meeting, (CoP17; Johannesburg, 2016) the Conference of the Parties adopted Decision 16.162 (Rev. CoP17) which directs the Standing Committee to re-establish the working group on annotations, in close collaboration with the Animals and Plants Committees. At its 68th meeting (Johannesburg, 2016), the Standing Committee agreed that Canada and Namibia would lead on the issue of annotations. 4. After discussion with the Chair of the Standing Committee in February 2017 and consultation between Canada and Namibia, it was agreed to engage members of the previous Standing Committee Annotations Working Group in advance of the 69th meeting of the Standing Committee (November 2017; SC69), to continue discussions relating to the work included in the working group terms of reference contained in Decision 16.162 (Rev. CoP17). In April 2017, in response to concerns raised by the Secretariat in advance of CoP17 regarding a lack of regional diversity in the working group in its discussions during the CoP16/CoP17 intersessional period, the Chair of the CITES Plants Committee confirmed that ten members or alternate members of the Plants Committee had expressed interest in participating in the Standing Committee’s work on annotations.

Ring characteristics of mahogany (Swietenia macrophylla K.) plantation trees grown in Taiwan were explored. Significant differences in average ring width (RW) and ring density (RD) occurred among three tree-diameter classes and three radial stages of ring numbers. RW in the radial direction decreased from the pith outward to the bark and followed a distinctive three-stage variation pattern (juvenile, transition, and mature zones). RD in the radial direction increased slowly from the pith outward to the bark. Wider tree rings and lower density are associated with juvenile wood close to the pith, whereas narrower tree rings and higher density are typical for mature wood outward toward the bark. RD in overtopped trees was higher than that in dominant trees. However, RW in dominant trees was wider than that in intermediate and overtopped trees. Earlywood density, latewood density, maximum density, and minimum density were the most important factors determining overall RD. There was a weak relationship between RW and RD, indicating that it is unlikely for growth rates of mahogany plantation trees to have a significant impact on wood density.

  • The Wood Cross Sections of Hermann Nördlinger (1818–1897)
    IAWA Journal, Vol. 29 (4), 2008: 439–457 THE WOOD CROSS SECTIONS OF HERMANN NÖRDLINGER (1818–1897) Ben Bubner Leibniz-Zentrum für Agrarlandschaftsforschung (ZALF) e.V., Institut für Landschaftsstoffdynamik, Eberswalder Str. 84, 15374 Müncheberg, Germany [E-mail: [email protected]] SUMMARY Hermann Nördlinger (1818–1897), forestry professor in Hohenheim, Germany, published a series of wood cross sections in the years 1852 to 1888 that are introduced here to the modern wood anatomist. The sec- tions, which vary from 50 to 100 μm in thickness, are mounted on sheets of paper and their quality is high enough to observe microscopic details. Their technical perfection is as remarkable as the mode of distribution: sections of 100 wood species were presented in a box together with a booklet containing wood anatomical descriptions. These boxes were dis- tributed as books by the publisher Cotta, from Stuttgart, Germany, with a maximum circulation of 500 per volume. Eleven volumes comprise 1100 wood species from all over the world. These include not only conifers and broadleaved trees but also shrubs, ferns and palms representing a wide variety of woody structures. Excerpts of this collection were also pub- lished in Russian, English and French. Today, volumes of Nördlingerʼs cross sections are found in libraries throughout Europe and the United States. Thus, they are relatively easily accessible to wood anatomists who are interested in historic wood sections. A checklist with the content of each volume is appended. Key words: Cross section, wood collection, wood anatomy, history. INTRODUCTION Wood scientists who want to distinguish wood species anatomically rely on thin sec- tions mounted on glass slides and descriptions in books that are illustrated with micro- photographs.

  • Carapa Guianensis Aublet Meliaceae Crabwood, Bastard Mahogany, Andiroba
    Carapa guianensis Aublet Meliaceae crabwood, bastard mahogany, andiroba LOCAL NAMES English (bastard mahogany,crabwood,carapa); French (cabirma de Guinea,bois rouge,carapa,andiroba); Spanish (andiroba,caobilla,najesi,cedro macho,masábalo,cabrima de guiana); Trade name (bastard mahogany,crabwood,andiroba) BOTANIC DESCRIPTION Carapa guianensis is a deciduous or semi-evergreen, monoecious, medium-sized to large trees up to 35 (max. 55) m tall; bole straight and cylindrical; branchless up to 20 (max. 30) m; up to 100 (max. 200) cm in diameter, sometimes fluted, with short buttresses up to 2 m high. Bark surface flaking into squarish scales or in horizontal strips, light grey to greyish brown or dark brown, sometimes reddish; inner bark fibrous, red or pinkish brown. Young plants produce taproots but the trees tend to become surface rooted. Leaves alternate, paripinnate with a dormant glandular leaflet at the apex, exstipulate; leaflets opposite, entire. Shows gigantic leaves in the monocaulous juvenile stage, decreasing in size when branching is initiated. Flowers small, white, borne in a large, axillary or subterminal thyrse; unisexual but with well-developed vestiges of the opposite sex; tetramerous to pentamerous (max. sextamerous); calyx lobed almost to the base; petals slightly contorted. Fruit dehiscent, 4-lobed, pendulous, subglobose, woody capsule containing 2-4 seeds in each lobe. Seeds smooth, pale brown, angular, with woody sarcotesta. BIOLOGY Flowering period depends heavily on the climate but is usually concentrated in 1 short period per year. Pollination is probably by insects; trees are often found swarming with ants visiting extrafloral nectaries at shoot apices and leaflet tips. Usually only 1-2 fruits in an inflorescence mature in 8-12 months.

E-mail: Abstract: The Rondônia Natural Resources Management Project (PLANAFLORO) was a strategic program developed in partnership between the Brazilian Government and The World Bank in 1992, with the purpose of stimulating the sustainable development and protection of the Amazon in the state of Rondônia. More than a decade after the PLANAFORO program concluded, the aim of the present work is to recover and share the information from the long-abandoned plant collections made during the project’s ecological-economic zoning phase. Most of the material analyzed was sterile, but the fertile voucher specimens recovered are listed here. The material examined represents 378 species in 234 genera and 76 families of angiosperms. Some 8 genera, 68 species, 3 subspecies and 1 variety are new records for Rondônia State. It is our intention that this information will stimulate future studies and contribute to a better understanding and more effective conservation of the plant diversity in the southwestern Amazon of Brazil. Introduction The PLANAFLORO Project funded botanical expeditions In early 1990, Brazilian Amazon was facing remarkably in different areas of the state to inventory arboreal plants high rates of forest conversion (Laurance et al.
