Is Balsa Good for Carving by Hand?

Balsa wood is a good carving wood for beginners because of its softness and low density. But, it has a tendency to create fuzzy surfaces, so sharp tools are a must. Plus, Balsa doesn't hold nails well—think glue for all your joining needs. Why did the carver carry a bottle of glue? To stick with the plan!

Balsa wood (*Ochroma pyramidale*) is a hardwood that is super light and soft, making it easy to carve. Because it's so soft, you need to keep your tools very sharp to avoid fuzzy surfaces. Remember, it’s not good for nails, so always use glue when putting pieces together.

  • Hardwood: Despite being soft and lightweight, Balsa is technically a hardwood.
  • Density: Very low density at 9 lbs/ft3, making it one of the lightest commercial woods.
  • Workability: Easy to work with, but can create fuzzy surfaces if tools are dull.
  • Uses: Commonly used in model airplanes, surfboards, and fishing lures because of its buoyancy.

“Carving Balsa is like dancing on air—light, effortless, but always needing the right moves.

Shrinkage of Balsa

Balsa wood exhibits shrinkage in unique ways, with radial shrinkage at 2.3%, tangential shrinkage at 6.0%, and volumetric shrinkage around 8.5%. The T/R Ratio is 2.6, indicating its relative stability upon drying. Why did the Balsa wood always keep its cool? It knew how to stay humble under pressure!

When Balsa wood dries, it shrinks in size, but not all parts shrink equally. Radial shrinkage is how much it gets smaller across its width, and tangential shrinkage is how much it shrinks around its circumference. Volumetric shrinkage tells us how much the entire piece of wood loses volume as it dries.

Radial Shrinkage:
2.3%
Tangential Shrinkage:
6.0%
Volumetric Shrinkage:
8.5%
T/R Ratio:
2.6
