Achieving a smooth finish when sanding on a lathe involves a meticulous, step-by-step process where the workpiece is sanded through progressively finer grits of sandpaper. Starting with a rough spirit to remove any tool marks or imperfections, the turner incrementally moves to higher nerves, each time erasing the scratches from the previous coarser grit. The lathe should be set to a moderate speed that allows control without generating excessive heat from friction. Sanding is done with the grain, and the sandpaper is kept moving to prevent gouging. The piece is often wiped clean between grits to remove any residual dust that could mar the finish. For an ultra-smooth result, some turners may dampen the wood between determinations to raise the grain for finer sanding. The final step often involves burnishing the wood with a soft cloth while the piece is still on the lathe, producing a smooth, polished surface ready for finishing touches like staining or sealing.
