Attentions in the uses of brush sander

• The brush sander machine has very little aggressiveness.

The brush sander machine cannot do the sanding to form the objects and profiles. It cannot clean up the putty or filler, either clean up the chatter marks, knife marks, or deep scratches. The correction to the putty or uneven shapes must be done by hand sanding with a hand block or portable hand sander with a pad sander. A brush sander will only smooth the surface by cleaning or cutting the wood fibers in the wood surface.
The sharp knife or chisel should be used to make a carved form, profile, or other complicated form product. The sharp knife and the right cutting and carving are the best ways to produce the perfect shape faster with a better result. The shape correction in the sanding process requires a lot of effort and energy and usually will not give the perfect result.

• Use the grade of sandpaper properly.

The proper grade of sandpaper is needed in the brush sander machine. The cloth-back sandpaper is mostly used. To sand the raw wood, the # 150 to # 240 grade cloth sandpaper back is mostly used. While doing sanding in the finishing process, the stearate sandpaper is needed. The scotch brite can also be mounted in the brush sander to do the polishing.
