PACIFIC MAPLE Amoora cucullata

USES

Building Construction (F17). Flooring and staircase materials. Exterior joinery; including screening. Furniture; including custom made and production line, cabinet work. Interior; including mouldings and architraves, window and door frames, wall linings. Window joinery.

● Amoora is a very attractive wood, somewhat similar to dark-red meranti and Philippine mahogany (Shorea spp.). It produces a first class peeler log and had been much sought after for face veneer in plywood manufacture in Japan, South Korea and Taiwan.

● The timber is fairly uniform in colour with a straight or slightly interlocked grain. It saws readily and works well with both machine and hand tools to a smooth surface. Sands to a fine finish and takes a high polish, giving a satin lustre. Glues, screws and nails well.

● Quarter-sawn material seasons well with little degrade. Back-sawn material has a tendency to cup and/or twist especially in wide boards. Close stickering of boards at 450mm intervals and weighting tops of stacks during preliminary air-drying and subsequent kiln drying is advisable.

● Amoora is suitable for high quality furniture and cabinet work. In its 'finished' state, boards cut on the full quarter and highly polished, bear a striking resemblance to African sapele (Entandophragma cylindricum), with its dark red colouring and attractive ribbon grain figure. It is also suitable for joinery, including window frames, door jambs, decorative (V.J) wall linings, mouldings, turning and outdoor (oil treated) screens; and makes an attractive flooring for light traffic.
