If finishing furniture is your forte, one of the most important things to consider is what is the best sander to sand unfinished furniture with. If the wood is not sanded properly, the grain can become warped and twisted, ruining the wood. Wood can be sanded improperly via two ways: either the wood is not sanded enough or the wood is sanded too much. Either way offers unique problems, but the most common example is that the wood is sanded too roughly, destroying or damaging the grain. There are other details to take into account when sanding wood but the important thing to keep in mind is the type of sander you buy.
Finishing sanders come in two varieties, block sanders and random orbit sanders. A block sander is exactly what it sounds, a block of sandpaper attached to a motor that imparts it vibration. A random orbit sander is heavier than a block sander. It consists of a large circular spinning block with sandpaper attached. Block sanders provide a better finish that random orbit sanders. Another obvious advantage is that, due to the size of the sander, block sanders can get into corners and nooks that random orbit sanders cannot due to their size. Random orbit sanders also require special sandpaper, unlike block sanders which use standard sandpaper that you can cut into whatever shape you need.
When purchasing a sander consider the following features:
- How fast the sander vibrates. Orbits per minute (OPM) is the most common measurement. Remember, a faster sander sands quicker.
- Some brands offer a variable speed option, which is worth considering if the price is low enough.
- Do not pay attention to the dust collection system; this probably will not work anyway. If you do want a dust collection system, be sure to buy a sander that comes with a hole punch system so that you can easily punch dust holes in standard sandpaper, rather than having to buy special paper (obviously this only applies to block sanders — orbital sanders require a special kind of sandpaper anyway).
Keep these principles in mind when buying a sander and you will be one happy customer.
