Quaruba (Vochysia tomentosa)
Family: Vochysiaceae
Common names: Barbara Chele, Bella Maria, Cambara, Chimbulla, Corosillo, Dormilon, Goma Amarilla, Gomo, Iteballi, Kouali, Kwari, Laguno, Mayo, Palo de Chanco, Plumero, Quaruba, Quarubatinga, Quillo, Quillosisa, San Juan de Pozo, Soroga, Wanakwar
Distributed in: Brazil, French Guiana, Guyana, Suriname (Central America, Latin America)
Distribution overview: The genus Vochysia is composed of several shrubs and trees that are distributed throughout tropical America, from southern Mexico to Peru, but are most plentiful in the Guianas and Brazil. Trees are reported to form almost pure stands on old farmlands, and attain their best development on coastal plains and along waterways.
Common uses: Boat building, Boxes and crates, Canoes, Casks, Chairs, Chests, Concealed parts (Furniture), Decorative plywood, Decorative veneer, Desks, Dining-room furniture, Dowell pins, Dowells, Drawer sides, Figured veneer, Fine furniture, Floor lamps, Furniture , Furniture components, Furniture squares or stock, General carpentry, Hatracks, Interior trim, Kitchen cabinets, Lifeboats, Living-room suites, Moldings, Office furniture, Packing cases, Paneling , Plywood, Radio - stereo - TV cabinets, Rustic furniture, Shipbuilding, Stools, Tables , Utility furniture, Veneer, Wainscotting, Wardrobes
Product sources: The ITTO reports that the species is an important source of timber and rates as a fairly important export.Timber produced by species in the genus are used for the same purposes as those by the genus Qualea, and the two genera are often referred to by the same vernacular name in some localities.
Environment profile: Status has not been officially assessed
Tree size: Tree height is 10-20 m
Colors: the heart isWhite, Yellowand the sapwoodWhite to yellow, Yellow.The grain isStraight, the textureModerately coarseand the lusterLustrous
Natural durability: Resistant to decay, Susceptible to attack by fungi and termites
Odor: No specific smell or taste
Kiln Schedules: T2 - D4 (4/4); T2 - D3 (8/4) US
Drying Defects: Severe cupping, Severe twisting/warping
Ease of Drying: Dries slowly
Comments: White Yemeri is reported to season more rapidly, but it is more difficult to work after drying.It also has very low resistance to decay in ground contact, and is only suitable for interior applications. Red Yemeri is more durable, is easier to work, and can be used for utility plywood, drawer bottoms, and panels
Blunting Effect: Slight effect
Boring: Satisfactory properties
Carving: Good results
Cutting Resistance: Easy to saw
Gluing: Good properties
Mortising: Good mortising properties
Moulding: Responds well to peeling after proper softening
Movement in Service: Responds well to peeling after proper softening
Nailing: Good nailing properties, Holds nails well
Planing: Woolly
Resistance to Impregnation:
Preservative absorption and retention is more than adequate in both heartwood and sapwood
Response to hand tools: Works readily with handtools
Routing recessing: Routes without difficulty
Sanding: Good sanding finish
Turning: Good results
Painting: Responds well to painting
; Polishing: Very Good to Excellent; Staining: Stains well
Water-Based stains should be avoided since they tend to raise the grain
