Single Brush Sander

A brush sander (often featuring a rotating brush drum or flap-wheel system) uses flexible abrasive bristles or overlapping abrasive strips instead of a flat sanding pad or belt. Because the bristles or flaps can bend and conform to shapes, it is used to sand, smooth, and finish surfaces that flat sanders cannot reach.

The three most common basic types of sanders are random orbital sanders (for general smoothing and finishing), belt sanders (for aggressive, rapid material removal), and detail/orbital palm sanders (for tight corners and edges).

A power sander is much faster and more efficient for heavy stock removal and large flat surfaces, whereas hand sanding is better for delicate contours, tight corners, and final touch-ups where control is critical.

Never skip more than one grit step at a time (for example, moving from 80 grit to 120 grit, rather than straight to 220), because skipping too many grits leaves deep scratches from the coarser paper that finer grits cannot efficiently remove.

The pencil trick involves lightly scribbling a zigzag pattern across a wooden surface with a pencil before sanding; as you sand, the pencil marks act as a visual guide, disappearing completely only when the entire surface has been evenly flattened and smoothed.
