Know Your Wood: Sapele

Sapele
A substantial specimen, even in the jungles of the Congo.

Common trade names: Gold Coast cedar, Assie sapelli, Lifari, Sapele mahogany, Scented mahogany, West African Cedar

Genus: Entandrophragma cylindricum

Janka Hardness (pounds-force): 1480

Description: Red to purplish brown, medium to dark. Color will darken over time. Figuring is a prominent feature of Sapele, and there is a wide variety of patterns that occur in this species. Grain is generally wavy and interlocked. Moderately to very durable to rot. Some insects will get after Sapele.

Location: Central Africa, namely: Angola, Cameroon, Congo, Ghana, Ivory Coast, Nigeria, Zaire, Uganda, Togo, Central African Republic, Gabon.

Common Aliases: Liboyo, Odupon, Penkwa, Tshimay noir, M’boyo

Performance: Tearout can occur more frequently than with most due to the interlocking nature of the grain. Furthermore, a chemical reaction resulting in staining may occur when put into direct contact with iron. Weird wood here.

Acclimation: For air drying, simply allow a half-inch or so among parallel planks stacked and spaced by level. It’s that easy, and in two or so weeks’ time, the lumber is ready for installation in your climate!

Common Uses: Musical instruments, furniture, boatbuilding, turnings, knick-knacks, veneers, plywood.
