These are some tips  when using the palm sanding machine.

  •  Use a sanding machine to sand the small volume job
This machine however is a hand sanding machine that is designed for small-scale work. For sanding job  on a wide  surface especially with large volumes, then we  should use big sanding machines such as: stroke sander or wide belt sander. The sanding result by the hand sander is  highly depend on the consistency of the operator job. The uses of this machine on the width and big area is highly risk of the uneven surfaces because of the inconsistencies of the operator.

  •  Use sandpaper type and grade according with the sanding job.
The proper selection of sandpaper is very important to get maximum results. Use the coarse sandpaper to sand the rough wood surface, and then gradually use the finer sandpaper.  For sanding the sealer or top coat we need to use sandpaper stearated sand paper.

  •  Apply the sanding machine with the correct movement
Move the machine smooth and regularly, avoid the too strong pressure. too strong pressure  is make the vibration is hard and high risk to damage the the pad or the motor.  Replace the sandpaper  soon if he's dull, or filled with dirt. The blunted sandpaper can no longer work to do sanding but polish the surface, which is make uneven surface. The dirt  attached  on the sandpaper  will cause scratches or spiral marks on the surface.

  • Use this tool for sanding the flat surfaces
This tool is actually designed for sanding on a flat surface. The uses to sanding the shape or uneven surfaces will make the surface to be eroded and changed forms. Uneven surfaces will also high risk of the damaged pad of the machine.

  •  Attach the sandpaper on the pad sander evenly
These machines are usually equipped with a clamp to hold the sandpaper to so it is fasten attached to the pad. Some types of sandpaper are already equipped with a special glue at the back side so that it can be directly stick to the pad. The sandpaper that does not have glue on the back side should be attached to  the pad by clamped. Avoid using double-sided tape to attach the sandpaper because it will produce an uneven surface. The uneven sandpaper surface is high risk to damage the pad since the uneven surface.

  •  Wear protective equipment when do the sanding.
The sanding process always create lot of dust that can interfere the breathing . The dust is can pollute the skin. Therefore wear a mask and work clothes and  gloves when doing the sanding process. Some types of machine are equipped with bag for dust collector to capture the sanding dust.  Make sure that the dust bag is work well to minimize the dust generated.

  1. Thanks for the palm sander tips - these are extremely useful! I actually tried to sand a piece of furniture that was uneven and I think I botched it. Any power tool you can recommend in case I need to do it again?
