How To Use A Random Orbital Sander(7 Easy Tips)

Every woodworker and every DIY-er have numerous tools that they use in their line of work. Their greatly used tool is the random orbital sander.

This tool is adequate for receiving a smooth and scratch-free result without any heavy handwork. Its operation is based on circular motions and its usage is effortless.

How To Use A Random Orbital Sander?

Prepare the materials – by using the clamps you can attach safely the materials to the work surface. By doing so you prevent the material from slipping or from any unpredicted kickbacks. After you have secured the material, bind it to a ventilator system. This process will gather the dust released from working.

Connect sandpaper – sandpaper comes in many grits. Before starting the process of sanding you must first choose the right grit. The coarse grit with 40 or 60 is good for the materials that require heavier sanding, it fastens the work. Regardless, this grit may leave nicks on materials that do not require rougher sanding. Instead, use a finer grit with 180 and 220. They might require more time but the results are a perfectly smooth surface.                                                                                         

Once you have picked the right sandpaper grit bind it with the sander. Usually, the random orbital sandpaper comes with an adhesive back. Peel it off and attach it to the sander. At this part of the job, it would be wise to put on your goggles and mask to guard yourself against any sawdust.

  1. Begin to sand – launch the process of sanding by letting it go on full speed without placing it on the work surface. At an instant begin by moving it onward the wood grain. Direct it with equal pressure at all times. Pressing too hard may cause damage to the material.
  2. Finalizing – by using a third of the sandpaper pad, sand the edges of the wood. Thereon, after completing the edges and all areas turn off the sander. Clean any dust left with a clean cloth.

Sand slowly

A random orbital sander is a tool that is specifically created to function at a slower speed. The preferred speed is 10 to 12 seconds per liner, meaning almost an inch per second. Indeed, the speed is tremendously slow but that is how you get the best from this tool.

Avoid pressing down to the wood

Adding pressure on the material doesn’t make it better, even the slightest weight can make it worse. The tool’s weight along with the weight of hand is more than enough to get the desired results. If you put pressure you may slow down the motor. This causes slow progress of work as well as harm to the surface. Simply allow the paper to do its job. 

Clean the dust with a vacuum

Bind the sander with a vacuum so that it can clean the dust mid-air. Doing so can aid in random orbital sander’s efficiency. You reduce the dust that is between the wood and the paper, allowing the grit to touch the material not the dust constantly. Also, this reduces the time of completion. 

Stop tilting

If you see a spot or a burn mark you try tilting the sander to remove those marks. When it comes to that, try not tilting because a random orbital sander is created to produce a flat plane smooth surface. If it is required to remove certain marks do it by sanding with hand.

Use different grit discs of sandpaper

The reason why there are produced different types of grit discs is that they are designed to be used together. Each grit disc removes the scratches left by the last one. Using just one grit disc of sandpaper does not provide you with the desired result.

This does not mean that you have to use all types of grit discs and go on a line from 80 to 100 to 0120 to 150 to 180 to 200 and 220. Instead, you can use the grit discs from 100 to 150 and 200. 100 is used to remove scratch faster, the other grit discs are used to prepare the surface for a smooth final.

Finalize by sanding with hand

Using only a sanding machine will not provide you with a high-quality smooth surface. There are going to be a few slight marks left behind from the random orbital sander.

Once you have finish sanding with 220 sanders do the final sanding manually. By using a flat sanding block you can complete the project with high-quality smoothness. 

Don’t use too long a sanding disc

Using a sanding disc for a certain time is natural. But when you use it for too long the disc will not cut properly and fills with dust. When this happens you should take it off from the sander and replace it with a new one.
