Techniques for Sanding Wood by Hand

Most woodworkers use power sanding during the early stages of preparing a work piece, but hand sanding is usually necessary at some point, especially if the work includes moldings.

Most woodworkers use power sanding during the early stages of preparing a work piece, but hand sanding is usually necessary at some point, especially if the work includes moldings. You can, of course, do the whole thing by hand '" it just takes longer.

Always sand parallel to the grain, working from coarser to finer grits so that each application removes the scratches left by the previous paper or cloth.

You will find it easier to sand most components before assembly '" but take care not to round over the shoulders of joints or create a slack fit by removing too much wood. Restoring old furniture presents additional problems, such as sanding up to corners and possibly sanding cross grain where one component meets another.

Sanding flat surfaces

Stand beside the bench, so that you can rub your sanding block in straight strokes parallel with the grain. Sweeping your arm in an arc tends to leave cross-grain scratches. Cover the surface evenly, keeping the block flat on the wood at all times '" especially as you approach the edges of the work, or you may inadvertently round over sharp corners.

Sanding end grain

Before sanding end grain, stroke it with your fingers to determine the direction f the fibers. It will feel smoother in one direction than the other. To achieve the best finish, sand in the smoothest direction.

Sanding small items

It is impossible to clamp and sand small items using conventional methods. Instead, glue a sheet of sandpaper face-up on a flat board and rub the work piece across the abrasive.

Sanding edges

It is particularly difficult to retain sharp corners when sanding narrow edges. To keep your sanding block level clamp the work upright in a vice and, holding the block at each end, run your fingertips along each side of the work as you rub the abrasive back and forth. Finally, stroke the block lightly along each corner to remove the arris and prevent splinters.

Sanding moldings

To sand a molding, wrap a strip of sandpaper round a dowel or a shaped block. Alternatively, use a foam-backed abrasive or an impregnated nylon-fiber pad.
