Product Sources
Shorea genus is a major timber source in international trade. They are plentiful, and supplies are universally available, especially in the form of veneers. This popular wood is typically priced in the inexpensive range.

Many species in the Shorea genera are also a source of other economically important non-timber products. Seeds of some species yield fat which is used in the manufacture of chocolate. Others produce nuts, the most common of which is the illipe nuts of commerce produced by S. gysbertisiana . The nuts yield a fat which is similar to cocoa-butter in some of its properties. Shorea trees are also tapped for oleo-resin, and typical dammar is obtained from S. wiesneri which grows in Java and Sumatra. The tree of S. robusta produces dammar which is used as a disinfectant and as incense in religious ceremonies in India. Other non-timber products from Shorea are reported to include tannin and fibers.

Blunting Effect
Slight blunting effect on cutting tools


Boring
Fair to good results
Fairly easy to very easy
Easy
Clean and smooth surfaces
Bored surfaces are usually clean


Carving
Fair to Good Results
Fairly Easy to Very Easy
Respond very well to carving operations


Cutting Resistance
Easy to saw
May be some break away at the base and back cut when sawing lighter stock
Good sawing properties


Gluing
Takes glue well


Mortising
Fair to Good Results
Fairly Easy to Very Easy
Good mortising properties
Easy mortising operations
Bores readily with ordinary tools, with very good results


Moulding
Fair to Good Results
Fairly Easy to Very Easy
Responds readily to ordinary tools in boring operations to produce clean surfaces
Responds readily to machine tools


Movement in Service
Excellent Stability - Small Movement
Holds shape well in service
Good dimensional stability and shows little movement in use


Nailing
Satisfactory nailing qualities


Planing
Fair to Good Results
Fairly Easy to Very Easy
Planing with standard tools is satisfactory if they are kept sharp
Interlocked grain may cause some tearing, and a reduced cutting angle of 20 degrees is recommended in planing

The timber exudes resin and oil but they do not interfere with machining operations

Resistance to Impregnation
Permeable sapwood
Permeable heartwood
Resistant to very resistant to preservative treatment
Fairly permeable


Response to Hand Tools
Responds Readily
Easy to Work
Yields a smooth, clean finish
Responds well to hand tools


Routing & Recessing
Fair to Good Results
Fairly Easy to Very Easy
Routs easily with ordinary machine tools
Produces clean surfaces


Sanding
Fair to Good Results
Fairly Easy to Very Easy
Lighter stock may produce rough surfaces in sanding
Denser stock sands well


Screwing
Takes screws satisfactorily


Turning
Fair to Good Results
Fairly Easy to Very Easy
Turned surfaces of lighter stock may be somewhat rough
Easy to turn
Denser stock is reported to turn well


Steam Bending
Wood buckles severely
Very poor


Polishing
Fair to Good Results
Fairly Easy to Very Easy
Good polishing properties after filling


Staining
Stains satisfactorily after surface preparation


Strength Properties
Weight=Medium
Not hard
Dents and marrs easily
Density=High
Compression strength (parallel to grain) = medium
Bending stength in air-dried condition...is medium
