Machining
Despite the high density and the interlocked grain, Cumaru wood can be machined well. The surface will be rather smooth, with exception of interlocked grain. Pre-drilling is necessary. Drying goes slowly with low shrinkage and less risks of warp or checks.

Remarks
FSC Cumaru is available in modest quantities in the Amazon region of Brazil. The tree has a straight trunk with a diameter till about 120 cm and less defects. It is also possible to produce larger dimensions. The sapwood is just a few cm wide. The so called tonka beans from this tree are used as an alternative for vanilla in for instance ice-cream.
