Yellowwood relief carving test


Yellowwood, Real (Podocarpus latifolius) – CNC Router carving test

Real Yellowwood carved with clear cutting lines and great relief detail during the CNC router test. Test was run on a single relief with a 1/4′ router bit. The rotation speed versus feed rate is not critical. The wood produced a clear surface with good developed shavings. Due to the carving lines, sanding was required starting at P120. Throughout the carving process the relief remain clear of any burs. The wood is suitable for all reliefs.

Distribution: East and South Africa
Other Names: Outeniqua yellowwood, Real yellowwood, East African yellowwood, broad-leaved yellowwood, red-fruited podo
 Characteristics: Yellowwood has a fine, even texture and a straight grain, although it is prone to spiral growth. It is light, but fairly hard and strong. Careful seasoning is required to avoid warping, twisting and surface checking.  The wood is yellow and quite similar to P. falcatus, the Outeniqua yellowwood, although not as dark or of the same quality. The bark is greyish and smooth when young but shows the characteristic longitudinal fissures as it matures.
Working Qualities: It planes well and works to a good finish and takes stain and polish well.

Uses: Yellowwood, often traded as ‘podo’, is highly valued for furniture and ship building, e.g. for masts and planks, but it is also used for poles, panelling, boxes, veneer and plywood. It is popular for making butchers’ blocks because it is fairly hard, without scent, and does not chip easily. It is suitable for construction, flooring, joinery, interior trim, vehicle bodies, railway sleepers, toys, novelties, agricultural implements, musical instruments, coffins, food containers, vats, carving, pattern making, matches, turnery, hardboard and particle board. It is also used as fuelwood, and it is considered a high-quality pulpwood.
