Drying Defects
Moderate twist/warp
Slight spring/bow
Moderate surface checking
Moderate end spitting

Small squares (used for archery bows) have a tendency to warp during drying. Irregular grain may cause twisting

Ease of Drying
Fairly Easy
Reconditioning Treatement
Little degrade
Variable results.
Irregular grain is difficult to dry
Good kiln-drying properties
Air-dries rather well


Tree Identification
Bole/stem form is straight
Bole/stem form is unknown
Bole/stem form is not buttressed
Bole/stem form is cylindrical


Tree Size
Tree height is 20-30 m
Trunk diameter is 100-150 cm


Product Sources
Unlike many timbers, the heartwood of Degame is of no commercial value, but the sapwood has many significant uses. The timber is very scarce on the U.S. market and is expensive since its primary source is Cuba.

Strength Properties
Bending strength (MOR) = high
Max. crushing strength = high
Hardness (side grain) = medium
Modulus of Elasticity (stiffness) = high
Shrinkage, Tangential = fairly large
Density (dry weight) = 46-52 lbs/cu. ft.
Shrinkage, Radial = moderate
Shearing strength (parallel to grain) = medium
Modulus of Elasticity (stiffness) = medium
Shrinkage, Volumetric = fairly large
Shrinkage, Tangential = moderate
Shrinkage, Tangential = large
Shrinkage, Radial = large
Shrinkage, Radial = fairly large
Density (dry weight) = 53-60 lbs/cu. ft.
Shrinkage, Volumetric = moderate
Shrinkage, Radial = small
Max. crushing strength = medium
Compression strength (parallel to grain) = high
Bending strength (MOR) = very high
Bending strength (MOR) = medium

Bending strength in the air-dry condition (about 12 percent moisture content) is exceptionally high. It is far superior in strength to either Teak or Hard maple. Maximum crushing strength, or compression parallel to grain in the air-dry condition, is in the very high range. It is stronger than Hard maple, White oak, or Teak. It is hard - harder than Teak, and does not marr or dent easily. It is a very heavy wood. The species has very high density.
