**You’re pulling a self‑bow and one limb is tighter than the other—dangerous, frustrating, and totally avoidable.** In the next few minutes you’ll learn a repeatable, low‑cost method that guarantees **even limbs** and lets you **measure draw weight while tillering a bow** with just a bathroom scale, a ruler, and a few simple habits. Follow the steps, take notes, and watch your bow flex like a single, balanced piece of wood.

## Common Tillering Mistakes to Avoid  

- **Guessing the bend** – Relying on feel alone leaves you shaving too much wood from the wrong side.  
- Using a makeshift **tillering stick** (e.g., a slippery PVC pipe) that can’t hold consistent pressure.  
- Ignoring **draw weight** during the process, which leads to a bow that’s either too weak or painfully heavy.  
- Skipping documentation – without notes you can’t see what each shave did to the flex pattern.

These errors turn a promising stave into a wobbly, unsafe bow. Recognizing them is the first step toward a reliable tillering routine.

## Simple Bathroom‑Scale Method for Even Limbs  

1. **Choose a target weight** that matches the draw you want (e.g., 30 lb).  
2. **Place a bathroom scale** under the stave, centered at the grip.  
3. Pull the bow down until the scale reads the chosen weight.  
4. **Mark every inch** along the limb with a light pencil line.  
5. At each mark, **measure the gap** between the limb and a flat surface (or a ruler placed against the opposite limb).  
6. The side that lags behind gets a **tiny shave**—no more than 0.3 mm—using a sharp rasp or fine file.  
7. **Re‑measure** the same points, repeat until the gaps are equal across the length.

Because you’re using a known weight, you’re effectively answering **how to tiller a longbow without a tillering stick** with precision you can trust.

## Step‑by‑Step Tillering a Selfbow  

| Step | Action | Why It Matters |
|------|--------|----------------|
| **1** | **Set up your workspace**: stable workbench, scale, ruler, rasp, pencil, notebook. | A consistent environment prevents accidental slips. |
| **2** | **Record baseline measurements**: weight used, initial bend at each inch. | Baseline data lets you track progress and avoid over‑shaving. |
| **3** | **Pull to target weight** and **measure** each side at the marked inches. | Directly shows which limb is lagging. |
| **4** | **Shave the lagging side** in controlled, hair‑thin strokes. | Small removals keep the wood strong and the curve smooth. |
| **5** | **Re‑measure** immediately after each shave. | Confirms that the adjustment moved the limb toward parity. |
| **6** | **Log every change**: weight, location, amount shaved. | Patterns emerge (e.g., tip vs. handle) that help **how to measure draw weight while tillering a bow** accurately. |
| **7** | **Repeat** steps 3‑6 until the gap between limbs is ≤0.5 mm at every inch. | Guarantees balanced flex and safe draw weight. |
| **8** | **Test the bow** with a light draw, watch for “set” after a few shots, then fine‑tune if needed. | Final fine‑tuning naturally evens out any residual differences. |

**Tip:** Keep your notebook on the bench; a quick glance at yesterday’s numbers prevents accidental over‑shaving.

## Final Checklist & Next Steps  

- [ ] Use a **bathroom scale** (or any reliable weight) instead of a makeshift tillering stick.  
- [ ] Mark measurement points at **every inch** along the stave.  
- [ ] Shave **no more than 0.3 mm** per pass; always re‑measure.  
- [ ] Record **weight, location, and amount removed** after each pass.  
- [ ] Aim for **≤0.5 mm** difference between limbs across the entire length.  
- [ ] After the first few draws, check for natural “set” and adjust if necessary.  

By turning tillering into a data‑driven routine, you eliminate guesswork, protect the wood, and achieve a bow that feels like a single, harmonious spring. Try the bathroom‑scale method on your next stave—you’ll be amazed at how quickly the limbs even out, all without spending a dime on expensive tools.
