Rhodesian Teak (Baikiaea plurijuga) – CNC Router carving test
Rhodesian Teak wood carved smooth and retains detail during the CNC router test. Test was run on single relief with a 1/4′ router bits. The rotation speed versus feed rate is not critical. The wood produced a clear surface with good developed shavings. No post processing was done on this relief. Throughout the carving process the relief remain clear of any burs. The relief surface have darker rings that are not consistent, this does make an impact on the visual quality of the relief. Wood and relief choice will be critical to use the nature of the wood. I have seen many fantastic hand carvings from Rhodesian teak where the nature of the wood was used to a great advantage.

Family – Fagaceae
Distribution: South Africa, Angola, Botswana, Namibia, Zambia and Zimbabwe.
Other Names: African teak, Mukusi, Rhodesian teak, Zambian teak or Zambesi redwood
Characteristics: The heartwood is an attractive reddish-brown with prominent, irregular black streaks and flecks. The pale pinkish-brown sapwood is sharply demarcated from the heartwood.The texture is fine and even. The grain is straight or slightly interlocked. The durability of Rhodesian teak is excellent. It is moderately resistant to termite attacks.
Working Qualities: Difficult to work with as it has a blunting effect on blades. Preboring should be done when nailing and screwing. Good finishes are generally obtained, timber planes well is easy to turn and polishes well with good varnishing properties.
Uses: A versatile wood, its uses include furniture, flooring, decking, cabinetry, turnery and carving.
