Characteristics of a Good Orbital Sander

Good Motor Quality

The motor is the heart of the operation of every ROS. It drives the disc to spin ad ensure uniform motion across the surface. Hence, it is important that your motor capacity matches your purpose and workload.

Adjustable Rotations Per Minute

Although this is related to the motor capacity, it is equally important to evaluate the rotations per minute or RPM. Generally, these devices run at 12000 rpm. However, there are models running as slow as 1600 rpm depending on the use. for versatility purposes, some users prefer variable speed sanders where you have the option to choose a speed that suits your work.

Cost Effective

Some products may cost you hundreds of dollars. On the other hand, there are models that cost less. In order to be a smart buyer, you need to weigh the pros and cons in terms of performance and costs. For example, I will prefer a product that costs a little extra but long lasting over a cheap sander that breaks down easily.

Ample Size of Disc

Usually, most products use 5-inch discs as this is the most ideal dimension of an effective sander disc. However, on special cases, you may want to select a smaller or bigger disc as needed.

How to Use a Random Orbital Sander

To achieve the best result when using an orbital sander, it is vital to understand the tool, its main function as well as how it is used. Well, this is a handheld power tool mainly used to sand surfaces especially wooden surfaces by employing sanding blade which delivers a random-orbit action. It is able to produce a finer and elegant finish which is as a result of a combination of abilities. As a matter of fact, it combines the sander belt abilities such as speed and aggressiveness to achieve a random circular action.

Following the fact that this is a hand-held tool, it thus requires expertise of an experienced tool. Failure to ensure this then the end results will not be pleasing. It is also vital to mention that through this tool, various distinctive designs can be produced. This is achieved when a sanding disk is spin simultaneously into small ellipses. The main advantage of using this tool is that it does not leave swirl marks which tend to be irritating thus making a piece of work to have undesirable qualities. Another fact that will make you want to use this tool is the fact that they come with integrated dust collectors hence they are environmental friendly.

Well, now it is time to start using the sander step by step until a desirable finish is achieved:

First of all, one needs to prepare the working surface using old newspapers to ensure safety and ease during work. Then consider assembling all the required materials that will enable you to transform a rough surfaced piece of wood to that desirable, appealing and beautiful finish. For instance, when using any sander one requires safety glasses, sandpaper, dust mask, hearing protection, old newspapers and clamps to mention a few things.

Did you know that you can employ two random orbit sanders at the same time to speed up the action and save time? Other than spinning it around the orbit, it will as well gyrate which will be influenced by the movement of your hands. At the end of the day, this will probably lead to a scratch free surface.

Double the action: Following the fact that this is a light hand-held tool, a professional can easily double the action and the effect by grabbing a second one. Now using both hands, this indicates that the rate of sanding is doubled. When employing the double effect technique, the sanders must be kept close to each other and sand as if you are using the same tool or one tool. Well, it is also important to be conscious while using this technique as in case the hands will stay apart while sanding then chances are that you will over sand the fabric.

Sand faster with suction:  the whole process of sanding through this tool can be made simple and enjoyable only if one opts for the right grit. Well, the following are some sanding grits to put into consideration: 240,120 and 60 respectively. 60 is for the roughest, 120 is for medium and 240 for the smoothest. To make the work easier, set the right grit for specific texture. For instance, if the piece of wood is rough, start with 60 and before anything else, it’s crucial to align the holes for the suction

Skip grit: I know this will sound funny but I wish to inform you that you need not to use each grit while sanding. You can use 70-230, 120-180-240 among others. This will require an expert who had done such work before who will be able to observe the piece of wood and choose the right grit as sanding continues.

Stop the swirls: actually a good an experienced expert will know when to stop the swirls. Did you know that too much pressure as well as speed creates tiny swirling scratches? For this case, one is only needed to rest the hand on the sander without pressing it. Swirls will probably interfere with the end results of your piece of work hence ensure that they are avoided at all cost.

Know when to stop:  since most woodworkers can measure the smoothness that they would require, they say that one should know when to stop which depends on the type of wood that is being worked on. For instance, open grain is best for hardwood such as mahogany while grain is good for softwood such as cherry. This will also depend on the kind of finish that is employed for instance one stops at 150 when they are employing thick coatings.

Gang sanding across the grain to save time: when there are lots of work to be finished within no time, one only needs o sand across a bunch of edges in a single pass.

It is vital to mention that the end results of using a R.O. sander depends on the professionalism of the user. It requires experience and knowledge to manipulate it across the wood so that a quality and desirable smoothness is achieved. Without this, then one will realize lots of shortcomings such as having swirls all over the wood. Moreover, the right selection of these tools also plays significant roles in achieving the best results.

It is worth mentioning that the best random orbital sanders come in different designs hence one can use those that accept peel-and-stick as well as use hook-and-loop discs respectively. They are easy to use, affordable and faster hence saves time.
