It is exported mainly in the form of decorative veneers. Queensland maple on the market is produced by two species (Flindersia brayleana and F. pimenteliana) Blunting Effect Little Boring Fairly easy to very easy Fair to good results Carving Fairly Easy to Very Easy Cutting Resistance Easy to saw Sawing properties are good Gluing Fairly Easy to Very Easy Fair to Good Results Good gluing properties Mortising Fairly Easy to Very Easy Fair to Good Results Moulding Fair to Good Results Fairly Easy to Very Easy Movement in Service Excellent Stability - Small Movement Prone to movement Medium Nailing Fairly Easy to Very Easy Fair to Good Results Holds nails well Good nailing properties Planing Fairly Easy to Very Easy Fair to Good Results Very Good to Excellent Results Interlocked grain causes pick-up planing A reduced angle of 20 degrees is recommended Resistance to Impregnation Permeable sapwood Resistant heartwood Permeable heartwood Resistant sapwood He heartwood responds poorly to preservative treatment.
