Embero

Scientific name: Lovoa trichiiloides Harms

Geographic origin: Africa.

Description

  • Sapwood: light yellowish grey.
  • Heartwood: greyish brown to grey.
  • Fiber: straight, with strong tendence to be intertwined.
  • Grain: thin to medium size.

Capacity of being impregnated

  • Sapwood: medium capacity of being impregnated.
  • Heartwood: nearly no capable of being impregnated.

Mechanization

  • Sawing process: no difficulties, except irritation due to irritating dust.
  • Drying process: speed can vary from medium to high speed. Little risk of deformation and crack formation.
  • Planing process: no difficulties except  the risk of repelling produced by pieces of intertwined fibers and the previously mentioned of irritating dust.
  • Gluing process: Risk of staining due to the use of alkaline glues.
  • Nailing and screwing process: risk of crack formation. Pre-drilling is recommended.
  • Finish: no difficulties.
