Symptoms
- Cut drifts away from the traced pattern line
- Detail cuts come out rougher than expected
- Blade seems to lag behind hand movement
- Fine details are hard to follow accurately
Likely causes
- CommonFeeding faster than the blade can cut cleanlyPushing the wood too fast makes the blade deflect off the line.
- CommonDull blade needing more force to cutA dull blade needs pushing harder, which increases wandering.
- PossibleWorkpiece not held flat against the tableTilting the wood changes the cut angle and can pull it off the line.
- PossibleBlade too coarse for fine detail workCoarser blades are harder to steer precisely on tight patterns.
What to do
- Slow the feed rate and let the blade cut at its own pace, especially on detailed sections.
- Replace a dull blade with a new one appropriate for the material.
- Keep the workpiece flat against the table throughout the cut.
- Use a finer-tooth blade for intricate patterns and tight curves.
- Trace the pattern clearly so the line is easy to follow at a glance.
- Practice on scrap with the same pattern style before cutting the final piece.
Tools and parts
- Scroll saw
- Fine-tooth blade
