Random orbit sanders have really simplified the painfully boring task of sanding. But, seeing how humans are always looking for simpler and simpler ways of doing things, here are 4 tips for even more effective use of the random orbit sander. If you want a more thorough guide to using this tool, you can check out http://woodworkify.com/sanders/random-orbital-sander/
1. How to Sand Multiple Edges Faster
You can cut down on time spent sanding multiple edges with your random orbit sander by gang sanding. This also actually does both your work pieces and the sand paper some good.
Firstly, the broader surface of stacked-up panels makes it less likely for the sander to grind too deep on one spot. Secondly, narrow edges result in unevenly worn sandpaper. It is not unlikely for poor grade sandpaper to get ripped as you work on narrow edges.
Furthermore, when sanding narrow edges, the sander may tip to one side resulting in unevenly rounded corners. By gang sanding, you get perfectly square panel edges.
All in all, you get to save on time, sandpaper, and electricity since the machine runs for a shorter time.
2. How to Monitor Your Sanding Progress
Sometimes, especially when soft-sanding, it might be hard to see the progress of your random orbit sander. There is a little trick you can do to make it easy for you to notice just how much you are sanding. It involves making random marks all over the wood surface you’re working on.
The trick is to make light marks without sinking the pencil lead into the wood. As you sand, the pencil marks will disappear if your sander is really doing its job. This can also work to enable you to avoid leaving sections of your large workpieces unsanded. Spread the marks all over the surfaces and sand until they all disappear.
3. Use Premium Grade Sandpaper
A penny saved is a penny earned, and who doesn’t like to save a dollar on a purchase? But, when it comes to sandpaper, and pretty much most things, going for the cheapest grade can prove costly both money and time-wise.
Premium grade sandpaper comes with sharp grit which affords a good bite into the wood, enabling it to smoothen wood surfaces faster. Some high-quality sandpaper will do the job up to three times faster than the cheaper type.
High-quality sandpaper will have its grit firmly attached to the sheet enabling it to last much longer – up to three times- than low-grade paper. Some types are so bad that instead of wood dust, you end up with actual loose grit all over your wood surface, a non-abrasive sandpaper, and an ever rough workpiece.
4. Slow Passes for Faster Sanding
It seems logical to make fast passes in a bid to get a smooth surface much faster. But, in fact, with a random orbit sander, slower is faster.
Quick passes will not only take time to remove the rough top layer of wood but once it does, it will also leave nasty scratch marks on your surface. Instead, use slow, steady passes for maximum contact between the sandpaper and the wood; and, therefore, quicker, smoother results.
The same applies to the amount of pressure you apply. It might seem as if the more pressure you exert on your sander, the faster it eats away at your wood. But, the opposite is true. Well, there is an optimal amount of pressure needed for the random orbit sander to work perfectly, and that is amply provided by the weight of the machine itself and the weight of your arms.
Too much pressure will limit the osculation of the sander and this will result in, you guessed it, scratch marks.
5. Keep the Dust Off
The random orbit sander, and of course any sanding mechanism, works on contact between the wood and the sandpaper. But as you sand, dust accumulates and forms a thin layer which cushions the wood from the grinding grit of your sandpaper. This renders the sander inefficient and you end up wasting time and energy.
Most random orbit sanders have dust filters which are meant to hold wood dust. However, these usually prove none too effective. The best is to attach a vacuum to your sander for completely dust free sanding.
