Some similar but separate species are reported to grow in the Amazon basin. Heartwood Color Brown Red Yellow Purple Orange Pink Yellow to golden-yellow to orange Black Greenish to greyish Older trees develop heartwood that is darker in color than the pale yellow sapwood. Sapwood Color White Yellow White to yellow Well defined Same as heartwood The sapwood, which is commercially preferred over the heartwood, is pale yellow in color Grain Straight Even Straight The grain is typically straight Texture Coarse Medium Fine Luster Medium Lustrous Pronounced Medium Dull Natural Durability Moderately durable Durable Perishable Susceptible to insect attack Non-resistant to powder post beetles Non-resistant to termites Non-resistant to marine borers Non-durable Non durable Susceptible to attack from powder post (Lyctid & Bostrychid) beetles Perishable Moderately durable Durable The timber has little or no natural resistance to attack by decay causing organisms and other wood destroying insects. Resistance to abrasion is high. Odor No specific smell or taste Drying Defects Distortion Checking Splitting Slight surface checking Slight end splitting End-grain should be sealed to prevent the wood from checking Ease of Drying Fairly Easy Slowly Volumetric shrinkage is rather high Moderate Difficult Material from Panama is moderately difficult to air-dry Kiln Drying Rate Naturally dries slowly Very slow Drying rate is slow Tree Size Trunk diameter is 100-150 cm Bole length is 10-20 m Sapwood width is 5-10 cm Tree height is 20-30 m Tree height is 30-40 m Bark width is 10-15 mm Trunk diameter is 150-200 cm Trunk diameter is 200-250 cm The tree is slender, growing to height that is rarely more than 50 feet (15 m) and a diameter of about 18 inches (45 cm). Product Sources Commercial use of Lancewood is on the decline. Although supplies are adequate, availability thorugh retail outlets in the US is limited. Boards are seldom available in widths greater than 5 or 6 inches (13 or 15 cm), which limits the use of Lancewood as a cabinetwood. Younger Lancewood trees are preferred over older trees since they contain a higher proportion of the commercially useful sapwood. Comments General finishing qualities are rated as good The wood is very strong, extremely elastic, and has good resistance to abrasion. The mechanical properties given are those of species in the genus that grows in Panama and corresponds to a basic specific gravity of 0.75 Blunting Effect Moderate Blunting effect on machining is slight Blunting effect on machining is moderate Blunting effect on machining is fairly severe Boring Fairly easy to very easy Boring operations are moderately difficult because of high density Carving Heartwood is very difficult to treat Cutting Resistance Easy to saw Cutting Resistance with green wood is difficult Cutting Resistance with dry wood is difficult Moderate to fairly difficult to saw Mortising Very Good to Excellent Results Fair to Good Results The wood is very dense, and may be moderately difficult to mortise, but it works to yield smooth surfaces Moulding Moderate moulding characteristics Nailing Possible if prebored Planing Fairly Easy to Very Easy Very Good to Excellent Results Fairly Difficult to Very Difficult Fair to Good Results Planes well, to a good finish Planing yields smooth surfaces Moderately difficult to plane High density makes wood difficult to plane and work Resistance to Impregnation Resistant heartwood Resistant sapwood Resistance to Splitting Poor Response to Hand Tools Easy to Work Difficult to machine Easy to machine Moderate working qualities Routing & Recessing Routing is easy Sanding Very Good Sanding Properties Screwing Poor results Possible if prebored Turning Fairly Easy to Very Easy Very Good to Excellent Results Fair to Good Results Good results Easy to turn Finish is generally satisfactory Excellent It is reported to cut and shape like Hickory. Steam Bending Unsuitable Poor to Very Poor Results Polishing Very Good to Excellent Results Fair to Good Results Satisfactory results Good results Lancewood takes a high polish Staining Finish is generally satisfactory Finish is generally good Strength Properties Density (dry weight) = 61-67 lbs/cu. ft Shrinkage, Tangential = large Shrinkage, Radial = large Density (dry weight) = 53-60 lbs/cu. ft Density (dry weight) = 31-37 lbs/cu. ft. Shrinkage, Tangential = fairly large Shrinkage, Radial = fairly large May require special tools to process Density = high The species is considerably stronger than White oak or Teak.
