Bubinga
BUB
Bubinga works well with both hand and machine tools, though irregular grain may pick up during planing or moulding, so a low cutting angle should be used. It has a moderate to severe blunting effect because it contains silica. There can be problems with gum exudation, and steam-bending qualities are poor. Gum pockets may make gluing difficult. It takes stain easily, an can be sanded and polished to...
Ebony
EBO
Ebony is a dense, hard and heavy wood. The black heart is usually very brittle. Because of its hardness and brittleness, Ebony can be very hard to work with both hand and machine tools. The wood has a fairly severe blunting effect on cutting edges. Gluing is rated as satisfactory to difficult, but the wood turns well and can be brought to a first-class finish.
Padauk
PAD
Padauk is a heavy, dense and resistant to wear. It has a high crushing strength, low stiffness and resistance to shock loads, and medium bending strength. It works well with hand tools, but the interlocking grain has a moderate blunting effect. The wood turns, saws, glues, screws and sands well, and can be brought to a good polish.Please note, the image is an example of what you could create with Padauk...
Wenge
WEN
Wenge is a heavy and dense wood which is highly resistant to abrasion. It has a high resistance to shock loads and high bending strength, low stiffness, medium crushing strength and a low steam-bending rating. The wood works well with both machine and hand tools, and has a moderate to medium blunting effect on cutting-edges. Gluing and polishing can be difficult because of the resin cells in the wood....
Zebrano
ZEB
Zebrano is a hard, dense and heavy wood with high strength properties and very high stiffness. It is not suitable for steam bending. It works well with hand tools and in most machining operations. Planing can be tricky, since interlocked grain can tear badly, so sanding is advised for a final finish. Gluing is satisfactory if care is taken. Please note, the image is an example of what you could create...
