Quaruba
Quaruba (Vochysia lehmanni)

Family: Vochysiaceae

Common names: Barbara chele, Bella maria, Cambara, Canelito, Chimbulla, Corosillo, Dormilon, Goma amarilla, Gomo, Iteballi, Kouali, Kwari, Laguno, Mayo, Palo de chancho, Plumero, Quaruba, Quarubatinga, Quillo, Quillosisa, San Juan de pozo, Sorog

Distributed in: Brazil, Mexico, Peru, Venezuela (Central America, Latin America)

Distribution overview: Several species in the genus Vochysia are distributed throughout tropical America, from southern Mexico to Peru, and are most abundant in the Guianas and Brazil. They are reported to form nearly pure stands on abandoned 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.Vochysia timbers are used for the same purposes as those produced by the genus Qualea, and the two genera are often referred to by the same vernacular name in some areas.

Environment profile: Status has not been officially assessed

Tree size: Tree height is 10-20 m

Colors: the heart isPale red to pink, Yellowand the sapwoodColor not distinct from heartwood, White to yellow.The grain isStraight, the textureModerately coarseand the lusterLustrous

Natural durability: Perishable, 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: Reconditioning Treatement

Comments: 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

Moulding: Good moulding properties

Movement in Service: Good moulding properties

Nailing: Easy to nail, 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: Routing is easy

Sanding: Good sanding finish

Turning: Good results

Painting: Responds well to painting ; Polishing: Good; Staining: Stains well Water-Based stains should be avoided since they tend to raise the grain ;

The bending strength of air-dried wood of the species is similar to that of Teak, which is considered to be strong. Compression strength parallel to grain, or maximum crushing strength, is medium. It is lower in this property than Teak. The wood is soft, and surfaces may dent easily. It also does not wear well, and mars easily. The weight is about average. The wood is high in density.
