Random Orbit Sander Buying Guide
Sanding isn’t the most fun DIY or carpentry job, however, when done well it makes a huge difference to the finish of your project. Luckily, the best random orbital sander can take out a lot of the hard work. You will get the job done in a fraction of the time and be ready for the more fun job of applying paints and finishes.
The best random orbit sander can be used for a variety of DIY tasks including removing paint and varnish, preparing and smoothing wood and metal surfaces, removing stains and blemishes and polishing glass, plastic or metal.
The best random orbital sander for you will depend on the size of your task, how frequently you expect to use it and your budget. Sanders come in a range of prices and qualities with a variety of features. Of course, if you only need your it for a one-off job them a cheaper item may be more suitable. However, if you plan on using your sander a lot it might be worth investing in a higher end product that will give you the power, versatility and durability you need.
Either way, you should look for a sander with a variable speed and a good dust collection system as this will make the job more pleasant as well as avoiding unwanted scratches or gouges.
A random orbital sander has a round surface to which you can attach sandpaper discs with Velcro. When you turn the machine on, it will rotate and vibrate this surface. This provides an even sand with no circular patterns in the finished product.
There are several things to consider when buying the best random orbital sander. Here are some key things to check before you buy.
The motor size will affect how powerful your machine is, however, it is not the only factor to consider. You should also look at the orbits or revolutions per minute that the sander can achieve. The higher this number, the quicker your sander will remove material and the sooner you will get the job done.
Random orbit sanders come in both single speed and variable speed varieties. I would recommend choosing a model with variable speed as this will be suitable for a range of applications from tough wood preparation to light sanding of intricate work. Basically, the more material you want to remove, the higher the speed you will use. If you only have a single speed you are more likely to damage delicate surfaces and create gouges and scratches. However, if you simply want to sand large, flat surfaces like doors and worksurfaces than a single speed sander will be fine.
It is part of the nature of sanders that they will vibrate. However, the amount of vibration will depend on the design and whether the machine is fitted with mechanisms to reduce vibration. In general, the lower end models will produce more noise and vibration than higher end models.
The effectiveness of the dust collection is a major factor in choosing a sander. Sanding wood and painted surfaces creates a lot of dust and mess and this can be harmful to the lungs. It also gets everywhere, so if you are using a sander indoors you may well find dust throughout the house if you use a tool that doesn’t have an adequate dust extraction system.
Ideally, choose a machine with an effective integral dust collection mechanism or choose one that can be connected to a vacuum cleaner. Even then, you should still wear a mask for extra protection. You will reap the benefit of an effective dust collector in the reduced amount of clearing up you have to do.
In addition, working without efficient dust collection means that the dust collects on the work and can wear out the sandpaper and damage the sander.
Comfort in use
If you are sanding flat horizontal surfaces, then weight might not be much of an issue. However, using a heavy sander to sand vertically or above your head can be wearing, so choose a light machine. An ergonomic design and comfortable rubber grip handle also mean you can work for longer without fatigue.
What speed setting should I use on my random orbit sander to strip gloss paint from a door?
Most tough sanding jobs are easier with a higher speed setting. However, when stripping paint, especially oil-based paints, a high speed can create a lot of heat which warms up the paint and smears it as well as clogging the sandpaper. I would recommend starting with a medium setting and see how it goes. If the surface begins to feel warm after a few minutes and you notice paint smearing, then turn the speed down a little.
What grit sandpaper discs should I use with my random orbit sander?
The grit you use depends on the task you are working on. A low grit number, such as will 60 remove material faster so are ideal for smoothing down a rough surface, but they will leave a certain amount of scratching. Higher grit numbers, such as 180 will create a smooth finish. If you are finishing a piece of wood, you should start with a lower number and gradually change to a medium and then higher number to achieve a silky-smooth finish.
I sometimes get random gouges in the wood when I use my random orbit sander. How can I prevent this?
There are a few guidelines you should follow when using your sander in order to get the best finish and avoid scratches, gouges and damage.
- Turn on the sander and let it spin up to speed before applying it to the wood.
- Always sand with the direction of the grain
- Do not apply much pressure to the sander, just enough to keep it in contact with the surface
- Remove the sander from the wood before turning it off.
- When sanding a flat surface, ensure that 2/3 of the sander is in contact with the wood at all times to keep it level. If you go off the edges you can round them and create an uneven surface.
