💡 How to maintain precise arc radius and prevent point slippage when using a large woodworking compass on rough lumber?
Your accuracy depends on locking the joints and setting the right tip for the material you are cutting.
- Screw down the knurled thumb lever until the movable leg feels solid, keeping the exact span pinned against any vibration while you swing wide arcs.
- Pop the graphite stick in for quick scratch marks on soft wood, then swap to the hard metal point when you need sharp grooves that won't smudge out.
- Wipe excess sawdust off the hinge and slide a drop of oil in to keep the action loose, so adjusting the wings always returns to your favorite setup without sticking.
