Fixing Common Chatter Marks

Chatter marks are vertical ridges that ruin the smoothness of a surface. They are usually caused by vibration or an incorrect angle.

Adjusting the Angle

• Increase the angle of attack slightly to reduce chatter on soft woods like pine.
• Decrease the angle for harder woods like maple to ensure the blade bites into the surface.
• Check if the blade is too dull; a fresh edge will cut smoothly without vibrating.

Stabilizing the Tool

• Use a backer block or a sanding block to steady the scraper during the stroke.
• Ensure the wood surface is flat; warped boards can cause the scraper to bounce.
• Apply more downward pressure to dampen any vibration coming from your hands.

With these adjustments, you can eliminate chatter and achieve a flawless finish.
