Andiroba wood can be somewhat difficult to work with due to its high density. It has a blunting effect on cutters, and cutting edges need to be kept sharp. Pre-drilling is recommended for nailing. The wood has good stability and glues well. It finishes smoothly and accepts finishes and stains with good results.
