Radial and tangential shrinkage from 4-7% Dries at a fairly rapid rate Tree Identification Bole/stem form is buttressed Bole/stem form is straight Tree Size Tree height is 20-30 m Tree height is 30-40 m Tree height is 0-10 m Tree height is 10-20 m Under very good growing conditions, the tree is reported to develop well-formed boles that are free of branches for as much as 70 feet (21 m). Large buttresses reduce usable length to about 50 feet (15 m). Product Sources The ITTO reports that timber production from the species is low. Export potential is rated as fair. The wood is used for heavy construction, ship building, and railroad ties within its native range. When available, it is inexpensive compared to other imported woods. Comments General finishing qualities are rated as good General finishing qualities are rated as satisfactory Wood is strong enough for furniture applications but is prone to warping Blunting Effect High to severe Medium effect Boring Easy Moderately easy Cutting Resistance Easy to saw Cutting Resistance with green wood is difficult Cutting Resistance with dry wood is difficult Gluing Easy to glue Mortising Finishes well Finishes satisfactorily Easy to mortise Moulding Easy to mould Good finishing results Areas of interlocked grain affect mortising, moulding, and boring Movement in Service Stable Nailing Pre-boring required Pre-boring required for nailing & screwing Holds nails well Planing Fairly Easy to Very Easy Fairly Difficult to Very Difficult Planes to a poor finish Difficult to plane Easy to plane Interlocked grain may cause chipping Resistance to Impregnation Sapwood is permeable Moderately resistant Heartwood is resistant Resistance to Splitting Satisfactory Response to Hand Tools Easy to machine Moderate working qualities Variable qualities Difficult to machine Routing & Recessing Routing bits may cause resin in wood to burn or darken Sanding Fairly Easy to Very Easy Good sanding finish Easy to sand Satisfactory sanding results Sading belts burn and darken resin Screwing Screwing yields good results Turning Good results Easy to turn Finish is generally satisfactory Polishing Good results Staining Darkness of wood makes staining unnecessary Varnishing Very well Strength Properties Shrinkage, Radial = fairly large Density (dry weight) = 46-52 lbs/cu. ft.
