I am finding it difficult to get good quality basswood. Until now I have used Mid West products but now what is available is of poorer quality. Is anyone else having difficult? Thanks in anticipation. DMQ
Consistently of width, fine grain and availability.how did you judge the quality of Basswood?
Consistently of width, fine grain and availability.
Common Name(s): Jelutong Scientific Name: Dyera costulata Distribution: Malaysia, Borneo, and various regions in southeast Asia Tree Size: 100-200 ft (30-60 m) tall, 5-6 ft (1.5-1.8 m) trunk diameter Average Dried Weight: 28 lbs/ft3 (450 kg/m3) Specific Gravity (Basic, 12% MC): .36, .45 Janka Hardness: 390 lbf (1,740 N) Modulus of Rupture: 8,030 lbf/in2 (55.4 MPa) Elastic Modulus: 1,224,000 lbf/in2 (8.44 GPa) Crushing Strength: 4,250 lbf/in2 (29.3 MPa) Shrinkage: Radial: 2.3%, Tangential: 5.5%, Volumetric: 6.2%, T/R Ratio: 2.4 |
Color/Appearance: Heartwood color initially almost white, darkening to a yellowish brown color with age. Sapwood isn’t clearly distinguished from heartwood.
Grain/Texture: Grain is usually straight, or occasionally interlocked. With a uniform medium to fine texture and good natural luster.
Endgrain: Diffuse-porous; large pores in no specific arrangement, very few to few; radial multiples of 2-5 common; growth rings indistinct; narrow to medium rays usually not visible without lens, spacing wide to normal; parenchyma diffuse-in-aggregates.
Rot Resistance: Generally rated as non-durable to perishable regarding decay resistance, and also susceptible to insect attack.
Workability: Jelutong’s low density make it very easy to work with both hand and machine tools. Some gum buildup may occur on cutting tools, but overall results are good. Glues, stains, turns, and finishes well.
Odor: Jelutong can have a distinct sour odor while being worked.
Allergies/Toxicity: Although severe reactions are quite uncommon, Jelutong has been reported to cause skin irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
Pricing/Availability: Not commonly available in North America. The tree has been overharvested in some areas, though it is not actually threatened with extinction. Occasionally available as carving blanks or as lumber. Prices are moderate for an imported species.
Sustainability: This wood species is not listed in the CITES Appendices, and is reported by the IUCN as being a species of least concern.
Common Uses: Patternmaking, carving, and other small specialty wood items.
Comments: Jelutong is a lesser-known Asian species that’s appreciated for its uniform appearance, softness, dimensional stability, and ease of carving. The wood is used in much the same way as Basswood (Tilia americana).
In addition to being utilized for lumber, the tree yields a natural latex when tapped. This latex was used for chewing gum, though nearly all gum is now made from synthetic rubber rather than natural.
Hi Dave!
Who needs wood in the 1000th range. My father was a mechanical engineer and he had a test room for metals after turning and milling. Constant temperature and humidity! That is not possible with wood! I read that once in the summer the well-known model maker Bernard Frolich had the problem that his ship under construction was 1,5 mm shorter.
I wish you all the best and satisfied customers!!!
With best regards
Thomas
