After achieving the basic shape using coarse grits, the next step is switching to medium grits, such as 120 to 150. Medium grits continue the shaping process, refining the curves and smoothing out any imperfections left by the coarse grits. Ensure a consistent sanding motion is maintained, working evenly across the corners to achieve a uniform appearance.
Step 3: Fine Grits for Achieving a Polished Finish
As you approach the final stages of corner rounding, it’s time to employ fine grits, typically 180 to 220. Fine grits are crucial for achieving a polished finish on the rounded corners. They remove any remaining scratches or irregularities left by the medium grits, resulting in a smooth and refined surface. At this stage, the corners should feel soft, seamlessly transitioning from straight edges to beautifully rounded curves.
Step 4: Extra Fine Grits for Perfecting the Rounded Edges
For those seeking extra finesse and perfection, using extra fine grits beyond 220 can provide the desired result. Grits in the range of 240 to 320 are excellent choices for putting the finishing touches on your rounded corners. These grits leave the wood’s surface incredibly smooth and prepare it for applying finishes or stains, enhancing the overall aesthetic appeal of your woodworking project.
