A belt sander offers the benefit of reducing this thickness without sacrificing the quality of the whole piece. It’s recommended to use a flat surface when carrying out this task so as to spend less time having to move your equipment around.

When working with hardwoods, this can be somewhat daunting which is why it’s recommended to use a belt sander. Also due to their mobility (in-line belt sanders), these machines will save you a lot of time when dealing with large surfaces such as floors.

The machine offers an exceptional level of consistency across the surface, so you don’t have to worry about some places getting more chipped off as you are sanding. This technique is preferred when dealing with dry hardwoods.
  • Dressing Up a Poorly Done Saw Cut – The teeth of a saw usually leave some rugged chips on all wood surfaces, to evenly smoothen out the wood surfaces, you need to use a belt sander.

What Are the Types of Belt Sanders?

Belt sanders can be broadly classified into two.

  • Transverse Sander

Transverse sanders are well known due to their design whereby the motor is transversely mounted across the width of the tool. This places it right above the belt; this arrangement enables it to drive more power to the belt through the toothed belt. The machine is equipped with a set of reduction gears that are used to reduce the speed to manageable levels for thorough work.

Although the upper mounted motor does make the machine heavier to lift, the design makes it way much easier to control compared to other belt sanders. The sanding frame (optional) will further help in controlling the sander on flat surfaces and in the elimination of gouges.

  • In-Line Belt Sander

The In-line belt sander is characterized by its minimal built; one that often becomes an added advantage due to the increased stability. This can be attributed to the low center of gravity hence less prone to tipping. That said, the sander is still easy to operate because it does not require a lot of lifting.

The motor in this sander seats parallel to the belt and is connected to the sanding belt by a set of drive down gears. The platen is responsible for supporting the belt release lever as well as the sanding area. If you need to work on a workbench, then the flat top will come into play as you can now use it upside down without having to worry about stability.

Belt Sander Operation Overview

  • Prerequisites for Using a Sander

Not just anyone can pick up a sander and use it with ease. There are some prerequisites you need to meet in order to use a sander appropriately. It is highly important that you at least have some experience working with a sander, or have knowledge of how one works. You also need to be aware of how to clean the sander after you are done with it so that it stays in optimal condition.

Knowledge of sanding safety is also important to know before working with the machine. The correct grit levels are needed for the job, as well as the right type of material. It is also important to note that small wood pieces should not be held by hand. A mechanism should be used to hold the wood in place, so your hand is never in the way of the sander. Wear the correct clothing while sanding is also necessary.

  • What to Wear When Sanding

You cannot simply start sanding while wearing your everyday clothes. There is certain attire that should be worn to help keep you safe while completing your project. Safety glasses are the number one item you need while sanding.

They will protect your eyes from debris, such as dust and particles that come off of the wood while you are working on it. It is also necessary to wear a dust mask. This keeps dust and debris out of your mouth and nose, preventing you from breathing in the harmful materials.

Jeans and a long-sleeve shirt are ideal when sanding. This protects your body from getting poked with sharp wood pieces that may fly off while the sander is in use.

  • How to Choose the Best Sander Belt

There are two main types of belts used on a sander. One is a zirconia option, while the other is made from aluminum oxide. Zirconia is more aggressive and is ideal if you have a large project to complete. Grits coarser than 80 should use zirconia.

Small projects and simple sanding will do well with the aluminum oxide choice. It is the most commonly seen option. There are a cheaper khaki-color version and a brown premium kind.

  • The Right Belt Size

Most belt sanders come equipped with a three-inch belt. This is the standard size that most home projects require. A smaller two and a half inch wide belt is meant for a one-handed sander that handles small projects. This may be all you need at home if you know the work is minimal. Four-inch belts should be left to the professionals.

  • Choosing the Grit Level

The level of grit also needs to be chosen carefully. An 80-grit belt is one of the most common. This level works well for basic woodworking needs. A 120-grit is also available, offering much more power. Some do-it-yourselfers use this option as well. A 50-grit is much too coarse for most projects, and can really just be avoided in most cases. It can leave deep scratches if you are not extremely careful.

  • Use Proper Technique

You might think that you have to push on the sander to make it move and work. This is actually not the case. Pushing on the machine is a surefire way to develop gouges and create mishaps in your work. The sander should simply be guided with your hands. It will do the rest of the work on its own. Using the proper technique will help the sanding go smoothly, and prevent mistakes from happening. It is best to go slow and avoid changing speed or direction quickly. You should also keep the cord out of your way, simply by placing it over your shoulder so it is not left to hang in front of the sander.

Out of these five choices, the winner is the Makita Variable Speed Belt Sander. It meets the qualifications of an ideal home project sander. With 3 inch belts, a speed control dial, and a dust bag, the Makita is top of the line. It works on a variety of surfaces and is designed with the user in mind.
