The Axial library
Every article, organized by topic. Written from mechanics and manufacturer documentation, not from "that worked for me" folklore. Live articles are linked; the rest are on the bench.

Arrow Selection
The arrow is half the system. Diameter, material, spine, and weight all affect flight, tuning, and scoring in ways that compound setups, stabilizers, and releases cannot compensate for.
- ToolArrow Oscillation & Node Calculator — find the two points along the shaft that move least during oscillation; see how tip weight shifts them
- ToolArrow spine calculator — compound and recurve, with cam profile, rest type, FOC, and Axial's light-arrow recommendation

Shot Sequence
The shot as a mechanical sequence — anchor, back tension, follow-through, release — described the way a technician would describe it. Geometry and muscles, not mysticism.

- Shot SequenceTarget panic — understood

Diagnostics
Symptoms first, then causes, then real fixes. The difference between managing a symptom and correcting the underlying condition.

- DiagnosticsGroup size — what it measures, what it doesn’t, and what’s actually good
- DiagnosticsTiller tuning — what it changes and why compound archers should leave it alone

String Building
The core of what Axial teaches. Building a bowstring is a sequence — each stage sets up the next, and shortcuts anywhere in the process show up as creep, peep rotation, or peaking noise months later.
- ToolString thickness estimator — enter material, strand count, and serving to estimate finished diameter; includes reverse lookup for target diameter
- Part 1Equipment & jigs — what you need at the bench
- Part 2Layout & length planning — starting length, post-twist length, pre-serve length
- Part 3Strand equalization — the light pull that makes the bundle honest
- Part 4Twisting — 0.5 to 0.75 twists per inch, measured to a real target length
- Part 5Tensioning & burnishing — where the bundle actually stabilizes
- Part 6Serving — end loops, center serving, and the peep-strand question
- Part 7Stretching — the final 300-pound hold
- TechniqueCenter serving — how to start, how much tension, how to back-serve

Material Choices
Fibers, arrows, servings, D-loop material, nock sets, peep sights, and the small parts most builders default to without thinking. What each material is good at, and where it quietly costs you.

Bow Technician
Real bench work — for archers going deeper than owner-level maintenance. Press safety, draw-length work, cam adjustment, center-shot, and the tuning procedures that actually earn their name.

Competition & Practice
Scoring, structured practice, and the mental side of competitive archery. What scores actually mean, how deliberate practice differs from shooting arrows, and the psychology of performance under pressure.

Science & Mechanics
Why strings and bows behave the way they do. The physics is settled, but very little of it makes its way into shop advice. Connects measurable behavior to the choices at the bench.

Care & Maintenance
Keeping the string and bow in good shape between builds. When serving can be fixed, when the string should be replaced, and the owner-level care that doesn't require a press or a tech.
