Day 109: Recurve Bow Maintenance: String Care, Brace Height, and Storage

A recurve bow goes out of tune slowly. Nothing snaps dramatically — the brace height drifts down a few millimetres, the string starts to fray under the serving, and one afternoon the bow that grouped beautifully in June is throwing arrows all over the target. By then you've blamed your form for a month.

Maintenance isn't about babying the bow. It's about removing the easy explanations so that when something goes wrong, you know it's you.

Check Brace Height First — Always

Brace height is the distance from the string to the deepest part of the grip. It's the single number that tells you most about a recurve's health.

- Why it matters: brace height controls how long the string pushes the arrow and how much of the bow's stored energy is transferred. Too low, and the bow behaves harshly, gets noisy, and punishes release errors. Too high, and you lose speed and stress the limbs.

- How to check: measure with a bow square (or a straight rule held perpendicular to the string) from the throat of the grip to the string. Compare it to the manufacturer's recommended range for your model — not to a number you found online for a different bow.

- What changes it: string stretch, especially on a new string; a string that has been left braced in a hot car; and twisting or untwisting the string during setup.

If brace height has drifted, adjust it by adding or removing twists in the string, a little at a time, then re-measure. Do this with the bow unstrung-to-braced only at the recommended range — never force a string onto a bow to chase a number.

String Care: The Part Everyone Skips

Strings don't fail from being old. They fail from being ignored.

Wax it. Bowstring wax keeps the strands from drying and abrading each other. Apply a thin coat and work it in with your fingers until it's not tacky — roughly every few shooting sessions, and always before storage.

Inspect the serving. The serving is the wrapped section at the centre and at the loops. Look for separation, fraying, or a gap where the string strands are exposed. A worn centre serving will eventually cut into the nock area and change your arrow flight before it breaks.

Check the loops. Frayed or stretched end loops are a replacement signal, not a repair job. A string is cheap; a limb or an eye is not.

Keep it clean. Dirt and grit work into the strands. Wipe the string down, don't soak it, and never use solvents or oils not intended for bowstrings.

Limbs and Riser: A Two-Minute Inspection

Do this before every session, especially after transport.

1. Look along each limb at an angle in good light. You're checking for cracks, splinters, delamination, or whitish stress lines.

2. Run a cotton ball or your fingertips along the limb edges. Any snag that catches is worth a closer look — this trick finds cracks you can't see.

3. Check the limb pockets and bolts for looseness. Takedown bows especially: hand-tight and consistent, not overtightened.

4. Inspect the arrow rest and plunger for wear or misalignment. A rest that has moved will scatter arrows and make you blame the bow's tune.

If you find a cracked or delaminated limb, stop shooting. There is no safe field fix for a compromised limb.

Storage: What Actually Damages a Bow

Most bow damage happens when the bow isn't being used.

- Heat is the enemy. A car interior in summer can soften finishes and stress limbs and strings. Store the bow indoors, in a stable temperature.

- Don't hang it by the string. Hang or stand it by the riser, or use a proper bow rack.

- Unstring for long storage if your model's manual recommends it, and store the string separately, waxed, in a sealed bag. Takedown bows pack down small — use that.

- Keep it dry. Damp storage attacks metal hardware and strings. If the bow gets wet, dry it thoroughly before it goes back in the case, and don't store it in a sealed case while damp.

- Store arrows separately and inspect them before the next session — a bent or cracked arrow is more dangerous than a tired string.

A simple vibration dampener pair is worth fitting if noise is your concern, but it doesn't replace tuning: dampeners reduce vibration, they don't fix a brace height that's out of spec.

A Maintenance Schedule That Works

Every session: visual limb check, string serving glance, rest alignment.

Every few sessions: wax the string, check brace height, tighten what needs tightening.

Monthly in season: full inspection — string loops, serving, limb edges, riser hardware, arrow condition.

End of season: clean and wax, check brace height, unstring if recommended, store dry and indoors, and note the date. Next season you'll know exactly what condition the bow went away in.

Your RB004 recurve — like any recurve — will hold its tune for years if you check these five things. Skip them, and you'll spend next season tuning a bow that was never out of tune in the first place.
