Working Properties: Overall Andiroba is easy to work with both hand and machine tools. Sometimes pieces with interlocked grain will experience tearout during surfacing operations. Andiroba also has a moderate blunting effect on tool cutters. Andiroba has an increased risk of warping and other drying defects, partially because of its high T/R ratio (2.5). Andiroba glues, finishes, and turns well.
