Then it turns into a circular path to make a sanded surface free of swirls.Which is why they are important for those who want are working on sanding wood with 90-degree types of joints on wood like stiles, furniture face frames, and rails.

Not only that but random orbital sanders alsousually cut more aggressively compared to other sanders. When you put lesser pressure on them, they would cut much better. They are also less stressful to use compared to a traditional pad and even with belt sanders.

In using the random orbital sander, they usually use disposable sandpaper discs. They are around five inches in diameter and are attached to the bottom of the sander. Before you turn on the random orbital sander, be sure that the material you’re working on is well secured.

Check and double check the material, this is because it can give you a better looking finished surface. Not only that a secure material will also prevent it slipping while you are working on it. You also would want to avoid any type of accidents in the future.

Step 2: Start The Ventilation

The random orbital sander has a ventilation feature. This helps in keeping your area clean and at the same time safe. Make sure that when you buy a sander, it has a reliable ventilation function. Ventilation also helps in keeping the sander in good condition.

Make sure that you have a firm grip on the handle before you turn the random orbital sander on. Set it gently on the material you are working on. Don’t turn on the sander on before you let it touch the material that you have placed there. This is to avoid creating any uneven surface.

If you have uneven surfaces, this can prove to be harder to correct in the long run. Which is why it matters that you mean how to control the sander and also adjust your movements so that it constantly moves from one surface to another.

Step 3: Have The Sander Moving Constantly

After turning on the random orbital sander, keep it moving. Move it and overlap it on the material you are working on. If you keep the sander in a single place for a long time, it can give the material that you’re working in, an uneven surface.

Some even recommend that you move the sander together with the grain of the wood to get that smoother finish. Always have the sander flat all the times, don’t tilt the tool when you move along the grain. This is to avoid unwanted circles and also creating an ugly appearance.

It might be hard to get rid of the circles after you work with the sander, which is why it is important that you also control the power from the sander and how you handle it. It can be challenging at first but you will get used to it as well.

Step 4: What To Do When Finishing The Edges

It is safer to stay away from the edges of the material that you have. Try to make sure that you finish the edges in case you need the round edges. When you round the edges while you work on the surface can be quite tricky and it can also make the material look bad and can even damage the sander.

Try to hold off from the edges as much as you can. Start with the surface first and when it is even, you can begin with the edges. Learn how to control your handling and also keep in mind that the sander is strong which is why you need to sand thoroughly but surely.

Step 5: Try To Make An Even Surface

If you want to make an even surface, do not press down the tool too hard. Bear in mind that when using a random orbital sander, it doesn’t require too much force when you 're using it. It is one of the easiest tools to use which is why you should check how you use it.

If you push it down too hard on your sander, it can create an uneven surface and you would not want that. It can also damage the sander and wear out the discs that it has, earlier than needed. When using the random orbital sander, you should also handle it with care.

After you finish working, remember not to take the tool off of the wood unless the random orbital sander is turned off. Look at the sander to make sure that it is turned off before you do anything. When it is turned off, clean it thoroughly before you use it again.

It is important to clean your sander after use because it can cause unwanted accidents in the future. Specs of dust in the dust bin or on the sander can ignite sparks and cause a fire in some cases. This is true when you work with metal since metals create sparks and wood dust can easily catch fire.
