How does a sanding machine work? An electric sander is a power tool used to smooth and finish surfaces. To remove material from a surface, the sander moves a piece of sandpaper or another abrasive rapidly, often in a circular motion.
Is it better to sand by hand or machine? Are the results the same, by hand or by machine? In reality, whether you are working by hand or with an electric sander, it all depends on the grain you choose. The more you sand with coarse-grained paper, the deeper you attack the surface. The smaller the grain, the lighter and smoother the sanding will be.
What is the fastest way to sand wood by hand? Slow and steady wins the race. For faster hand sanding, you just press harder and move faster. But with a random orbit sander, that strategy will actually slow you down. Too much pressure or speed creates tiny swirling scratches that you’ll have to sand out sooner or later (often later, after stain makes them visible).
Why would you use a power sander instead of hand sanding? Power sanders are much faster than hand sanding, and fast is the name of the game in collision repair. For example, if the tech hand sands with 400 grit, he or she can get the same scratch by using 320 grit on a random orbit power sander. The power tool moves much faster.

What is the proper way to sand wood?
Sand with the Grain
Close inspection of a piece of wood reveals pores in the surface that form a pattern called the grain. Always sand in the direction of the grain–never perpendicular to it or at an angle. This also applies when working on edges and hard-to-reach corners.
What sandpaper do I use for wood?
On most raw woods, start sanding in the direction of the grain using a #120-150 grit paper before staining and work up to #220 grit paper. Soft woods such as pine and alder: start with #120 and finish with no finer than #220 (for water base stains) and 180 grit for oil base stains.
What is the difference between an orbital sander and a finishing sander?
What Is the Difference Between an Orbital Sander and a Sheet Sander? Both orbital sanders and sheet sanders move an abrasive in a circular pattern. For instance, belt sanders work well for jobs that require you to remove lots of material quickly, while finishing sanders allow you to create an extremely smooth surface.
How much does a belt sander cost?
You’ll find 3 x 18-in. sanders for $50 to $150 and 3 x 21-in. sanders for $100 to $250 when looking for the best belt sander. You’ll also find smaller belt sanders that take 2-1/2-in.
Will a sander remove paint?
Sanders (including manual hand sanders and power sanders) are an effective way to remove paint from large, flat surfaces. Since a sander creates dust, it’s not safe to sand lead paint because it will release toxic lead dust into the air.
Can I use an orbital sander to remove paint?
The orbital sander rotates and vibrates. This lessens the risk of leaving a circular pattern in the surface. Both sanders remove paint with or against the grain of wood. The small, portable size makes these sanders the right tool to remove paint from flat or curved surfaces.
Is an orbital sander better than a palm sander?
As compared to a palm sander, orbital sanders are more massive tools, which means that palm sanders are smaller and more lightweight. The motions of orbitals are Circular and orbiting, and palm sanders only have orbiting motion. If you want to work with larger pieces, orbital sanders are better than palm sander.
Is a round or square sander better?
Advantages. The best feature of the orbital sander is its square shape, which allows it to get in corners and up against edges. Compared to sanding across the grain by hand or with a belt sander, they leave less obvious cross-grain marks, which means that it’s harder to ruin your work.
When should I use an orbital sander?
Preparing a surface before and after painting. With the vibrations in tiny circles, the random orbital sander is used for ultra-smooth sanding. It can be used on wood, plastic or for metal working.

What kind of sander is best for refinishing furniture?

Do you really need to sand wood before staining?
The best way to stain wood is to prepare the wood surface by sanding it with a sanding block or orbital sander. Sandpaper with a lower grit number will make wood rougher, allowing more stain to absorb and create a darker color.
How do you know when to stop sanding wood?
Be sure to progress up through every grit level; 60, 80, 100, 120, 150, 180, 220 and on. Typically you will want to stop at 180 or 220 if you are planning to stain the wood. Higher grits will close the pores of the wood and make it difficult for stain to penetrate.

Sanding blocks are my favorite tool for almost any sanding project.

Blocks are so much easier to handle and grip than sheets of sandpaper.
What will happen if you put too much pressure on a sander?
Avoid pushing down with too much pressure on the sander.
When you use too much pressure, the sander has to do more work to perform its rotations, this means there will be more work for the motor and more friction on the surface of the workpiece. Both of these things lead to more heat.
