Yellow-Heart

Yellow-Heart (also known as Pau Amarello, botanical name Euxylophora paraensis) offers several material properties that make it particularly well suited for use as arrow shaft footing wood. Its advantages mainly stem from an excellent balance of density, strength, and workability.

1. High Compressive and Impact Strength

Yellow-Heart is a dense and hard tropical hardwood. This is crucial for a footing, as the front section of an arrow shaft experiences the highest mechanical stress upon impact. The wood resists:

• Axial compression forces on impact
• Local crushing behind the point
• Micro-cracks that often cause shaft failure in softer woods

This significantly increases the durability of wooden arrows.

2. Favorable Strength-to-Weight Ratio

Compared to very heavy footing woods (e.g., ebony), Yellow-Heart provides high structural strength at a moderate weight. This offers two key advantages:

• The FOC (Front of Center) can be increased in a controlled way without making the arrow excessively heavy.
• Arrow flight remains balanced, particularly with medium spine wooden shafts.

3. Excellent Grain Structure

Yellow-Heart typically features:

• Straight grain
• Fine, even texture
• Uniform growth structure

This allows for precise glue joints between shaft and footing and reduces the risk of shear failure or delamination at the bonding line.

4. High Abrasion and Split Resistance

Compared to many lighter hardwoods, Yellow-Heart is less prone to splintering. When striking targets or in occasional hard impacts:

• The footing maintains its structural integrity longer
• Longitudinal splitting is less common
• Overall arrow lifespan is extended

5. Good Workability Despite Hardness

Although hard, Yellow-Heart machines well with sharp tools. It can be:

• Turned cleanly
• Sanded precisely
• Fitted accurately

This is especially important for thin footings, where dimensional accuracy affects arrow straightness and concentricity.

6. Aesthetic Appeal

Its distinctive golden-yellow color darkens slightly over time and provides an attractive contrast to common shaft woods such as cedar, spruce, or pine. This gives the arrow both functional and visual value without additional decoration.

7. Practical Comparison

In practical use, Yellow-Heart is generally:

• Stronger than maple or beech
• Lighter than ebony or snakewood
• More uniform than heavily figured exotic hardwoods

This makes it a technically balanced choice for durable, performance-oriented wooden arrows.

In summary, Yellow-Heart is an excellent footing wood when high mechanical durability, controlled front weight distribution, and good workability are desired—without resorting to extremely heavy exotic hardwoods.
