Primitive Bow and Arrow: Construction from Natural Materials

Wood Selection

Primary Bow Woods (North America)

Osage orange (Maclura pomifera): Yellow-orange heartwood. Dense, flexible, almost unparalleled for bow making in North America. Look for hedge rows and roadsides in the Midwest, East, and South.

Black locust (Robinia pseudoacacia): Excellent bow wood, very hard. Found throughout the East and as an invasive throughout North America.

Ash (Fraxinus spp.): Traditional bow wood. Excellent ring structure. Must use the back of a single growth ring for the belly/back configuration.

Osage orange is the recommendation for a first bow if it is in your region. The difference in performance between Osage and most other woods is substantial.

Understanding Wood Grain for Bows

A bow is a spring. The belly (facing the archer) is compressed. The back (facing the target) is stretched. Different grain types perform these functions differently.

The back must be strong in tension. For most woods, following a single growth ring on the back — using one complete ring as the back surface — maximizes tensile strength.

The belly must be strong in compression. Dense heartwood is better in compression than sapwood.

For Osage orange: Use the orange heartwood. Follow the outermost growth ring on the back. This is the classic Osage configuration.

For ash: Use a stave where the back is a single, flat, unbroken growth ring.

Stave Preparation

A stave is the raw piece of wood from which the bow is carved.

Green Wood vs. Dry Wood

Dry wood is strongly preferred. Dry wood has full structural integrity. Green wood (freshly cut) is flexible and will perform initially but continues shrinking, warping, and changing draw weight as it dries — often cracking at the most inopportune moment.

How to dry quickly (not ideal): Cut stave, seal the ends with sap, resin, or paint (prevents end-grain drying that causes splitting), store in shade with airflow. Dry 2-4 weeks minimum, 3-6 months for best results.

Survival scenario: Cut a stave, seal the ends, work it slowly over several weeks.

Selecting the Stave

1. Find a straight section of appropriate wood, 5-6 feet long, roughly 3 inches wide and 1-2 inches thick.
2. Split or carve the stave so one face is the natural back (outer wood) of the tree.
3. Flatten the back to a single growth ring.

Roughing Out the Bow

Bow dimensions (starting point):

• Length: 64-72 inches (AMO standard for a traditional longbow)
• Handle section: 6-8 inches at center
• Limbs: Taper from 1.5 inches wide at the fade (handle transition) to 1/2 inch at the tips

Basic profile: The bow is a rectangle with slight taper. Do not remove more wood than necessary at any one time. Tillering (adjusting the bend) cannot replace removed wood.

Tillering

Tillering is the process of removing material to make both limbs bend evenly and smoothly. This is the most critical and time-consuming step.

Building a Tiller Tree

A tiller tree is a simple measuring device:

1. Cut a notch in the end of a plank or log at about 1 foot from one end.
2. Cut additional notches at 2, 4, 6, 8, 10, 12 inches from the first notch.
3. Place the handle of the bow in the first notch.
4. Draw one limb toward you slightly and look at the bend.

The Tiller Process

1. String the bow loosely (very short brace height — 4-5 inches initially).
2. Place on tiller tree. Draw to 5 inches. Look at the limb profile.
3. A properly tillered limb bends in a smooth, even arc from handle to tip.
4. Identify where the limb is stiff (does not bend enough relative to adjacent areas) and where it is weak (bends too much).
5. Remove wood from stiff areas using a draw knife, file, or rough stone.
6. Never remove wood from weak areas — you cannot put it back.
7. Alternate checking both limbs at every stage.
8. Work slowly in small increments. Gradually increase draw length over multiple sessions.
9. Final brace height: 5-6 inches for a longbow profile.

Signs of over-stressing: White stress marks on the belly surface, cracking sounds, limb "following the string" (not returning to straight when unstrung) — a sign you are working too fast.

Bowstring

Materials (in order of reliability):

1. Sinew (back tendon of deer): Traditional bowstring material. Very strong. Must be dry-twisted and kept dry — sinew stretches when wet.
2. Dogbane (Apocynum cannabinum) fiber: Excellent plant fiber for bowstrings. Twisted 3-ply.
3. Nettle fiber: Strong, available.
4. Rawhide strips: Twist into cordage while wet, allow to dry on the bow at full brace height.

String construction: Twist multiple fibers into two-ply yarn. Twist multiple yarns together. The string for a 40-50 lb bow needs to be significantly thicker than you might expect — err toward stronger.

Arrow Construction

Arrow Shafts

Best materials: Dogwood shoots, shoot-of-the-year from various shrubs (straight first-year growth), river cane (Arundinaria spp., southeastern US), or any very straight small-diameter branch.

Requirements: Arrow shafts must be very straight, about 3/8 inch diameter, and as uniform as possible. Straighten green shoots by heating briefly over fire and bending while warm, holding until cool.

Spine (stiffness): The arrow shaft must flex appropriately for your bow's draw weight. Too stiff = arrow kicks away from bow; too flexible = arrow fishtails. A rough guide: a 30-50 lb bow needs shafts that deflect about 1/2 inch when supported at both ends with a 2 lb weight at the center.

Fletching

Three or four feathers stabilize the arrow's flight by creating drag at the tail.

1. Collect large flight feathers (turkey, goose, or similar).
2. Split the quill along the center.
3. Trim each vane to 3-4 inches long and 1/2-3/4 inch wide.
4. Attach three vanes in a spiral pattern (helical) about 1 inch from the nock end.
5. Glue with pitch glue (pine pitch mixed with a small amount of crushed charcoal) and bind with thread, sinew, or thin plant fiber.
6. Bind both ends of each vane.

Nock

Carve a notch perpendicular to the string at the tail end of the shaft. 1/4 inch wide, 1/4 inch deep. The string seats in this notch.

Points

Flint/obsidian/chert knapped point: The most effective but requires a separate knapping skill.

Sharpened hardwood point: Harden by charring the tip briefly in fire, then cooling. Effective for small game and birds.

Bone point: Split a bone into a point and bind to a foreshaft.

Metal: Any available metal shaped to a point and notched for binding.

Accuracy and Practice

A bow is useless without accuracy. Begin practice at 10 feet, shooting at a large target. Move to 15 feet, then 20, then 25 as accuracy develops.

For small game hunting, 15-25 feet is the practical maximum range for most beginning primitive archers. At this range, a consistent archer can take stationary small game reliably.

Practice the same shot process each time: nock, draw to anchor point, align sight picture, release. Consistency is accuracy.
