Primavera (Tabebuia donnell-smithii)
Family: Bignoniaceae Common names: Campeche, Chiapas, Copal, Cortez, Cortez blanco, Duranga, Durango, Flor de zope, Oaxaca, Palo blanco, Pequia marfim, Prima vera, Prima vera mahogany, Primavera, Roble, San Juan, Tabasco, White mahogany Distributed in: El Salvador, Guatemala, Honduras, Mexico, Nicaragua (Central America) Distribution overview: The geographical distribution of Primavera includes Central America, Mexico, Nicaragua, and Guatemala. The trees are reported to thrive on moist, rich soils, but have also adapted to dry areas. Common uses: Bedroom suites, Boat building (general), Boat building: decking, Boxes and crates, Building materials, Cabinetmaking, Chairs, Chests, Decorative veneer, Desks, Dining-room furniture, Drawer sides, Figured veneer, Fine furniture, Flooring, Furniture , Furniture, Heavy construction, Interior construction, Interior trim, Joinery, Kitchen cabinets, Light construction, Living-room suites, Millwork, Moldings, Office furniture, Paneling , Paneling, Radio - stereo - TV cabinets, Trimming, Veneer, Veneer: decorative, Wainscotting, Wardrobes Product sources: Primavera trees are grown also in plantations. Most of the material on the US market is believed to come from Guatemala, where the law requires Primavera logs to be processed and exported in lumber and veneer forms only. Supplies are scarce in the veneer form, but are somewhat available in lumber form in the United States. The material is priced in the costly range. Exports to Europe are very rare.The value and marketability of the material is dictated by the time of year the tree is felled: the sap of the tree rises and fall with the phases of the moon, and the best product is from trees felled in 'the dark of the moon', when the sap is low. Environment profile: Status has not been officially assessed Tree size: Trunk diameter is 150-200 cm
Colors: the heart isYellow, Yellow to golden-yellow to orangeand the sapwoodWhite to yellow, Yellow.The grain isWavy, the textureMedium to fairly course and the lusterPronounced
Natural durability: Susceptible to insect attack, Very durable Odor: No specific smell or taste
Kiln Schedules: T6 - F3 (4/4) US Kiln Drying Rate: Rapid (<10 days for boards < 32 mm, to <30 days for boards >= 63 mm) Drying Defects: Slight twist/warp, Splitting Ease of Drying: Slowly Comments: General finishing qualities are rated as good Harvesting tree at suggested period reduces sap exudation from log ends It is recommended that the tree be felled in 'the dark of the moon', since unlike trees in the temperate regions, the sap rises and falls with the phases of the moon instead of in winter and spring. Sap attracts insects that may damage the timber Sap content is reported to depend upon the time of yeat the tree is felled Subsituted for hard woods because it works easily in most machining operations Blunting Effect: Medium effect Boring: Good results Carving: Good results Cutting Resistance: Fairly Difficult to Very Difficult to saw Gluing: Fairly Easy to Very Easy Mortising: Finishes well Moulding: Good moulding properties Movement in Service: Good moulding properties Nailing: Pre-Boring Recommended, Thin boards are prone to split Planing: Very Good to Excellent Resistance to Impregnation: Sapwood is modertely permeable Resistance to Splitting: Poor
Response to hand tools: Responds Poorly Routing recessing: Routing characteristics are good Sanding: Sanding characteristics are good
Veneering qualities: No drying degrade. Dries flat without splitting, There is slight to moderate drying degrade and the potential for buckles and splits Steam bending: Seldom used for steam bending applications
Screwing: Pre-boring recommended, Thinner stock requires carefull screwing to avoid splitting ; Turning: Very Good to Excellent Results
Polishing: Very Good to Excellent; Staining: Stains well; Varnishing: Very Good to Excellent;
