Bending Multipliers Reference
| Angle | Multiplier | Shrink per inch | Use For |
|---|---|---|---|
| 10° | 6.0 | 1/16" | Slight offsets |
| 22.5° | 2.6 | 3/16" | Medium offsets |
| 30° | 2.0 | 1/4" | Standard offsets |
| 45° | 1.41 | 3/8" | Large offsets, kicks |
| 60° | 1.15 | 1/2" | Very large offsets |
