Panga Panga (Millettia stuhlmannii) – CNC Router carving test
Panga Panga wood carved smooth and retains detail during the CNC router test. Test was run on a single reliefs with 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 moment we get more of this wood type, the focus will be to use the natural light dark banding as part of the relief.
Family – Leguminosae
Distribution: East Africa
Other Names: Jambire, Partridge Wood, Wenge
Characteristics: Heartwood is Brown, dark brown, black to chocolate. Alternating bands of light and dark tissue. White to yellow to light brown. Distinct from heartwood.The wood has a characteristic partridge feathered figure. Texture is fine. Abundant small dark yellow gum pockets are present. Excellent stability in service and highly resistant to abrasion.
Working Qualities: This very heavy, dense wood has a high bending strength and resistance to shock loads, with a medium crushing and stiffness strength. It has a moderate blunting effect on cutting edges. Nailing requires pre-boring and the grain requires filling to be brought to a good finish.
Uses: Perfect for flooring strips, interior and exterior joinery and general construction work.
