Arrow Build & FOC Worksheet
Record components, compute FOC step by step. Print at A4 or US Letter, fill it in, then build your arrows with confidence.
What's on the sheet
- Component weight rows: shaft, point, insert, nock, vanes, wrap
- Measurement rows: arrow total length and balance point
- FOC formula spelled out so you can compute on the spot
- Target band reference: low, ideal, high, extreme
- Notes section for build observations and tuning context
