description [more
info]
Heartwood is light red coloured with an attractive grain. When
cut on the quarter the wide medullary rays show an oak like figure.
Sapwood is paler.
Wood
density [more
info]
Green density is about 945 kg/m3 and air-dry density about 560
kg/m3.
Shrinkage
[more
info]
Tangential and radial shrinkage are estimated as ... per cent respectively.
Workability
[more
info]
Sharp tools must be used on Banksias as they
all have a very open grain and tend to tear when dressing. Sanding,
gluing , drilling and turning are rated as good, carving is fair. Banksia
will take lacquer, wax and oil well, however, having such and open grain
it will require several coats to fill the grain. A wax finish is said
to give a silky finish.
