Padauk

Scientific name: Pterocarpus buettneri Taub.; P. Osun Craib; P. Tinctorius Welw

Geographic origin: Africa

Description

  • Sapwood: cream-coloured.
  • Heartwood: intense rojo colour that darkens into dark grey due to light effects. It frequently has dark grey streaks.
  • Fiber: Straight. Slightly intertwined fibers are very frequent.
  • Grain: medium size to rough.
  • Defects: white deposit bags

Capacity of being impregnated

  • Sapwood: Capable of being impregnated
  • Heartwood: Medium capacity of being impregnated

Mechanization

  • Sawing process: Hard and with some abrasive effects.
  • Drying process: Medium to low speed. Little risk of deformation and crack formation.
  • Planing process: Appart from hadness and abrasability difficulties, risk of repelling is very frequent in those cases of intertwined fibers. Suitable for carving and bending
  • Gluing process: Certain difficulties due to the oil content.
  • Nailing and screwing process: Pre-drilling is required
  • Finish: No difficulties
