A sander is crucial for many woodworking projects. Scouring the internet reveals very scanty information on a sander. The article below will explain to you all that you need to know about these sanding tools. You will discover what a sander is, types of sanders, and a buying guide for a superb sander.

What Is A Sander?

Sanders are hand-held manual or powered tools used in smoothening surfaces through the abrasive action of the attached sandpaper. The sandpaper grinds continuously against the rough surface that you want to smoothen. Sanders vary in sizes, and some are mounted on benches to meet various smoothening needs.

More details will emerge on sanders as you look into the various types that are available in the market.

Types of Sanders

As mentioned, there are several types of sanders. What you choose depends on the project that you are undertaking. They range from the simplest hand-held sanders for intricate carving to heavy-duty electric-powered sanders for sanding large surfaces. We have arranged them into manual and powered tools for ease of classification.

A) Manual Sander

The manual sanders are simple smoothening tools that you can make yourself. You will have to use your hands and energy for the tools to achieve the best outcomes. With the manual sanders, you can sand successfully on small tasks with minor rough surfaces and edges.

Advantages of Manual Sanders

-The tools sand at a slower speed, which results in very smooth surfaces.

Some of the manual sanders include;

1. The Sandpaper

You can buy sandpapers in any tools store near you. They come in several sizes ranging from standard to fractional sizes. Besides, you will realize that the sandpapers have grits on one side. The grits are the sharp edges that sand the materials. If you want more excellent sanding, select the sandpaper with small grits. However, for heavy sanding, choose the coarse sandpaper.

2. Strip Sander

This sander is similar to a hand-held wood planer. It has two handles for pushing the tool through as you sand. If you have ever used a hand plane, then this sander operates similarly. The handles allow you to sand a larger surface with ease.

3. Hand Sander

A hand sander has one handle that runs from the front to the back that holds the sanding surface. The grip makes the sanding easier compared to the simple sandpaper.

4. Bow Sander

Sanding on curved surfaces is much more comfortable using the bow sander. As the name suggests, it has a bow-like handle joined together by the sanding material. This formation gives you an edge when sanding contoured edges that require uniform pressure.

Factors to Consider When Buying a Sander

The market has many types and sizes of sanders. Choosing what you need may be tricky, especially if you are a beginner. However, you may ask yourself some questions to gauge what sander to buy.

1. What Is Your Specialty?

If you mostly deal with curved surfaces, you may consider buying an oscillating spindle sander. However, if you are a professional in floor finishing, the flooring drum sander is appropriate. These two examples mean that you need to check against each tool to arrive at the final decision.

2. What Are The Sizes Of The Materials That You Mostly Plan To Work On?

Large surfaces require a sander that works quickly and has sufficient power. Consequently, smaller surfaces may require hand-held sander for sufficient smoothing.

3. How Do You Want The Final Product To Look Like?

Different sanders differ with the smoothness level that they can achieve. Ask yourself whether you need outstanding finishes, or some swirls are allowed on your surfaces.

4. Are The Specific Sanding Pads Available?

A sander is a long-lasting tool. However, the sanding pads wear out with time. Therefore, you need to check on their availability as you will be replacing them from time to time.

5. How Versatile Is The Sander?

Space and other constraints may hinder you from buying certain types of sanders. Therefore, you need to enjoy most from the tool that you choose. Consider the space in your work station and select the device that will sand most of your needs.

6. What Budget Do I Have?

When it comes to costs, consider the initial price and the maintenance cost in your final decision. Sound judgment will help you in choosing the best sander that will not have future financial constraints.

A short recap for selecting your suitable sander

  • Orbital sander- ideal for beautiful finishes on medium surfaces
  • Random orbital sander- the tool of choice for super beautiful finishes with no swirls.
  • Belt sander-suitable for large surfaces in case you don’t need a very smooth finish.
  • Multi-tool –suitable for minor sanding tasks and where you can use it for other functions with different accessories
  • Hand-held sanders- ideal for occasional small sanding jobs
  • Detail sander- useful for sanding small and hard to reach areas

Now I hope you have made an informed decision on what sander you need. However, you need to visit a tools store and consider the following factors;

1. Lifespan

How is the body build of the sander? The machine should withstand long working hours without losing integrity within a short period.

2. Motor Power

This consideration depends on the type of materials and sizes that you will be working on. Note that the higher the motor power, the higher the sander’s strength.

3. Simplicity in Use

If you are a beginner in sanding, you need a sander that is easy to use. Besides, you need a sander that you are comfortable working with and have full control.

  1. Dust port

Sanders produce a lot of fine dust that could have health implications. Therefore, a power tool with a well-placed dust port is handy. Above all, the tool kit should have a well-sized dust bag for dust collection.

5. Available Attachments

It will be foolhardy to buy a sander and before long be back at the stores for replacements. It’s advisable to buy a sander with several accessories. They may include sheets of sandpaper, sanding discs, and dust bags, among others.

6. Variable Speed Control

Different working surfaces require varying sanding speeds. A sander with variable speed control is handy in protecting your boards from possible destruction.

7. Vibration Control

A sander with high vibration makes your hands very uncomfortable and could also be dangerous. If you want to work for long and enjoy your sanding projects, check for a sander with lower vibration levels.

In Conclusion

Sanding is a very cool project. However, it can be a pain, especially if you have the wrong tool for a given task. The trick lies with your plans and the level of versatility that you need in your chosen device. Go ahead and select your most appropriate sander and welcome to the world of fantastic finishes.
