Working Properties: Turns, bores, cuts, and otherwise works well with hand or machine tools. Glues, nails, and screws satisfactorily. Finishes well, especially with natural finishes.
Uses: Commonly used for shingles due to decay resistance and predictability of splitting. Also used for poles, posts, boxes, crates, caskets, siding, boat building, porch columns, saunas, canoes, and decorative veneers.

Physical Properties: Light and soft with moderately low crushing strength, low shock resistance, moderate stiffness, very good decay resistance and good stability in service.
Working Properties: Works easily with hand or machine tools but has some tendency to splinter. Turns well. Nails and screws easily but has poor holding properties. Glues quite satisfactorily. Accepts and holds paints exceptionally well.
Uses: Used mainly for building construction (siding, sash, doors, finish) as well as tanks, silos, fences, decks, outdoor furniture, boxes, crates, novelties, turnery, shakes, and boat building.

Physical Properties: Hard and heavy, moderate to high strength and shock resistance, low stiffness, good stability in service, and excellent decay resistance.
Working Properties: Works OK but has severe blunting effect on cutting edges. Pre-drilling recommended for screws and nails. Glues satisfactorily if precautions taken for oily surfaces (consider using epoxy resins). Finishes to an exceedingly smooth, highly polished surface.
Uses: Esteemed for centuries as one of the finest woods in the world for high-class furniture, cabinetry, and paneling. Also excellent for knife handles, brush backs, bowls, and other turned items. Other uses include piano cases, musical instrument fingerboards, billiard tables, levels, marquetry, and carving.

Appearance: Commonly interlocked grain with a uniform, moderately coarse texture. Purple-brown heartwood with attractive dark streaks and yellowish white sapwood, often with a purple tinge.
Physical Properties: Heavy, hard, and dense with high bending and crushing strengths, medium shock resistance, good stability and very durable heartwood.
Working Properties: Difficult to work due to calcareous deposits – dulls cutting edges. Holds screws and nails well and glues satisfactorily. Finishes nicely although filling recommended.
Uses: Primarily used for decorative and ornamental purposes including furniture, cabinetry, paneling, and turnery. Also used for musical and mathematical instruments, brush backs, inlay, sculpture, boat construction, hammer heads, and decorative flooring.
