Eight-Way TieStandard
Each spring tied to neighbors, frame, and diagonals — gold standard for seat longevity.
Spring SpacingFormula
Coils typically 3–4 in on center for seat decks; closer at front edge.
Spring TypesTable
Common seat spring systems.
| Type | Era | Repair |
|---|---|---|
| Coil 8-way | Antique | Retie |
| Sinuous | Modern | Clip replace |
| Marshall | Mid-century | Unit swap |
Spring Ends
Cut spring wire throws sharp ends — wear gloves and eye protection.
Frame Integrity
Do not retie springs on rotted frame — structural failure under load.
Twine Tension
Excess tension distorts frame; insufficient causes sag.
Safety Notes
- Secure piece on stable work table — springs store energy when compressed.
- Use knee pads — hours kneeling on frame rails.
