Adjustable Circle Marking Ruler for Woodworking

Mark a circle or arc on a panel before cutting. This adjustable plastic compass ruler is for woodworkers and makers laying out curves of different sizes.

• ✅ Change the radius between marks — Use the adjustable positioning arm.
• ✅ Lay out a curve on a flat panel — Rotate the ruler around the marked centre.
• ✅ Repeat an outline — Keep the radius setting between marks.

Set the radius for your layout

Mark the centre and set the radius before tracing. Hold the pivot steady and test the resulting circle on an offcut if it must match a part.

Use only part of the rotation to mark an arc. Check the line against your layout before cutting or drilling.
