Availability & Appearance
Although the resource is limited by quotas or predominant reservation, stocks of Myrtle are still available.
Available (mainly decorative thicknesses)
Dressed seasoned timber 40 to 300 mm wide by 12 to 40 mm thick. Undressed seasoned timber 25 to 300mm wide by 25 to 50 mm thick. Lengths up to 4500 mm long are available, with the bulk of production between 2400 and 3000 mm long.
Myrtle heartwood is pale pink to deep red, occasionally with pale yellow-grey streaks. Sapwood is white to light pink.
Grain is mainly straight and occasionally wavy with clearly visible growth rings.
Fine, uniform and smooth.

Myrtle cuts relatively cleanly and may be easily dressed to a smooth, lustrous surface.
An excellent bending timber. 25mm material bends well to a radius of 75mm.
Easy to drill. Holes are clean and to size.
Readily worked to a smooth, lustrous surfaced. Most finishes adhere very well. Staining can be difficult.
Glues satisfactorily with most common adhesives.
Surfaces are true and clean, even end grain.
Nails very well, material does not tend to split. Pre-drilling is often necessary in seasoned material. Nails hold well.
Moderate feeding forces required. Surfaces can be planed very smooth and lustrous.
Rebating + Mortising
Very good results may be obtained with relative ease.
Cuts very cleanly and accurately with standard blades.
Turns very well.
