One of the first rules of woodworking is sanding in the direction of the grain of the wood. , to avoid the formation of cross marks, that can jeopardize the finished look of your home. But when the pattern of wood fibers changes - for example, on the parquet floor, where grain direction changes from board to board - hard to sand, leaving no stains.
In such situations, one of the best (and the fastest) solutions is to use an eccentric sander - a power tool with a sanding pad, which simultaneously rotates and oscillates (revolves in orbit) in an elliptical pattern. This magical combination of rotation and oscillation significantly reduces sanding marks..
Let's clarify the frequently asked questions
Power sanders allow you to quickly smooth out rough finishes, flooring, railings and almost any other type of wood products, and random orbital sanders are among the most popular types of sanders due to their ability to smooth wood, without leaving obvious transverse traces. those, who completes their collection of power tools with orbital sanders, probably, there will be a few questions.
How Random Orbital Sanders Work?
Random orbit sanders use two different types of motion: rotational and oscillatory (elliptical movement). The combination of these two sanding movements prevents the sander from leaving marks on the wood.
What is the difference between orbital and eccentric sanders?
Orbital sanders simply spin. Random orbital sanders rotate in addition to, that the entire grinding head moves in an elliptical pattern. Try a random orbital sander, and then turn it on - your whole hand will want to move in an elliptical pattern. This is because of the orbital force of the sander.
What are eccentric sanders used for??
Random Orbital Sanders are used for the primary sanding steps, such as removing roughness or roughness from the surface of wood. They are often followed by sanding or a finishing sander., or manually with fine-grained sandpaper.
Are random orbital sanders finishing sanders??
Not, but using a random orbital sander will remove most of the roughness. After this you can use a finishing sander, to create a very smooth surface.
What to Consider When Choosing the Best Random Orbital Sander
There are a few things to keep in mind when buying an eccentric sander., which will help you choose, что лучше всего подходит для данных обстоятельств. Большой выбор моделей представлен https://www.bigam.ru/catalog/ekscentrikovye-shlifovalnye-mashiny-5786/
Below we will look at some of the most popular top models of corded and cordless eccentric sanders and help you choose the most top models.
Many random orbital sanders have a single speed, but some models have variable speed, which changes the aggressiveness of the grinder. Higher speed is useful for quickly sanding finishes and bumps (eg, when removing varnish from an old bookcase). A lower speed is better for fine sanding (eg, for a smooth table surface).
Besides, keep in mind, that while most tools use RPM as the speed standard, eccentric sanders use the term "opm", what does oscillations per minute mean. The fluctuations are, in fact, turnover, but with a random oval path, not a closed circle.
However, the lack of variable speeds should not be an obstacle, because success can be achieved, simply using sandpaper of the appropriate grit (rough for rough handling, medium for smoothing and fine for finishing).
The standard disc size for eccentric sanders is 5 inches in diameter, and any hardware store or home improvement center has a wide selection of standard 5" sandpaper discs. Home DIYers can also find grinders with smaller discs from 1 to 4 inches, which are convenient for grinding in hard-to-reach places.
For larger projects (eg, wood floor sanding) best fit discs with a diameter 6 inches or more. Depending on the size and model of your grinder, you may need to purchase a specific brand of sandpaper discs..
Some random orbit sanders come with attached dust bags, which collect some of the wood dust, formed during grinding. Others include nozzles, which can be connected to a standard wet/dry dust collection hose. These collection methods will not remove every speck of dust (always wear a dust mask when sanding), but they can significantly reduce it, so they are a good option to look for, especially when sanding indoors.
Random orbital sanders are fed in one of three ways: from electrical cords, batteries or compressed air (pneumatic). Each method has its own advantages.
Wired: Since there is no need to recharge the battery, mains-powered grinders always ready to go, if there is an electrical outlet nearby. Just plug in your corded random orbit sander and get to work..
Wireless: these grinders are great for grinding away from a power source, eg, when building a treehouse for children without an extension cord, long enough to reach. However, when using a cordless grinder, the battery limit needs to be taken into account.. Users usually receive 30 to 45 minutes without recharging, and many keep a spare battery on hand, to continue working, while the first battery is being charged.
Pneumatic: pneumatic grinders, compressed air, are a good choice for carpenter, which has a central air compressor to power a range of pneumatic tools. However, small pancake type air compressors are not always powerful enough to operate a grinder without frequent stops to recharge air.. For best results, use a pneumatic sander with an air compressor, which can produce a volume of air 40 cubic meters per minute or higher.
A typical 5-inch random orbital sander weighs between 1 to 3 kg. Mini grinders weigh only 1,5 kg, while larger eccentric sanders can weigh 3 kg or more. Lighter grinders are less tiring for hands and wrists, especially when sanding vertical surfaces, e.g. wooden panels.
Most random orbit sanders have a top handle for the palm of your hand., making it easy to maneuver with one hand. but, if there is a lot of grinding in the future, it might be a good idea to choose a model with an optional side handle, allowing two-handed control.
Some grinders and polishers also have a cylindrical handle, similar to some jigsaws. Barrel handle allows the user to keep their hand closer to the work surface, improving leverage and control.
