Long John (Triplaris surinamensis)
Family: Polygonaceae Common names: Bois fourmi, Formigueira, Fourmigueiro, Hormigo, Long John, Mierenhout, Palo hormiguero, Palo mulato, Palo santo, Santa maria, Tangarana, Vara de maria Distributed in: Bolivia, Brazil, Chile, Columbia, Costa Rica, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Suriname, Uruguay, Venezuela (Central America, Latin America) Distribution overview: Various species in the genus Triplaris are distributed from southern Mexico through Central America and tropical South America. They often grow predominantly in swamps and are also common on low riverbanks in Surinam. The trees are sometimes found in pure stands on abandoned clearings. Common uses: Boxes and crates, Building construction, Cabinetmaking, Construction, Cooperages, Fiberboard, Furniture , Furniture components, Furniture, Interior construction, Joinery, Light construction, Mine timbers, Particleboard, Vats Environment profile: Vulnerable Tree size: Trunk diameter is 100-150 cm
Colors: the heart isWhite, Yellowand the sapwoodWhite, Yellow.The grain isStraight, the textureMedium coarse to coarseand the lusterMedium
Natural durability: Susceptible to insect attack, Very little natural resistance against attack by decay fungi Odor: No specific smell or taste
Kiln Schedules: T6 - D2 (4/4) US Kiln Drying Rate: Naturally dries quickly Drying Defects: Ring Shakes, Splitting Ease of Drying: Variable results. Tree Identification: Bole/stem form is fluted Comments: General finishing qualities are rated as satisfactory Hollowed stems are reported to often contain aggressive ants, which tend to attack individuals felling the tree Blunting Effect: Moderate Boring: Fairly easy to very easy Carving: Good results Cutting Resistance: Fairly easy to saw Gluing: Responds well to gluing Mortising: Responds well to machine tools in mortising operations Moulding: Material responds well to moulding operations Movement in Service: Material responds well to moulding operations Nailing: Good nailing characteristics, Pre-Boring Recommended Planing: Poor to Very Poor Resistance to Impregnation: Resistant sapwood Resistance to Splitting: Poor
Response to hand tools: Responds Readily Routing recessing: Good routing qualities Sanding: Good sanding properties Veneering qualities: Veneers easily, Veneers moderately easy Steam bending: Unsuitable
Screwing: Pre-boring recommended, Very Good to Excellent Results; Turning: Fairly Easy to Very Easy
Painting: Fairly Easy to Very Easy; Polishing: Very Good to Excellent; Staining: Very Good to Excellent; Varnishing: Good;
