Topic tags/keywords: question sander

I was wondering if other LJs can shed light on a question has been burning on my mind for a few months. What is the practical use of variable speed for a 5” random orbit disc sander in woodworking. Is it useful for woodworking? If so, when would one take advantage of the lower speeds?

I never use the vs on my ros.

I have a porter cable, it’s not variable speed. But I attach a speed control on occasion.

Actually I hardly use an ROS anymore.

But when doing delicate work, I found the speed too much.
There are times when I just wanted to just take the fuzz off.
I now use a Bosch 1/4 sheet sander for that. It does a better job in general, but it eats paper. The ROS doesn’t. So if I didn’t have the 1/4sheet I would use the speed control more often when wanting to do verticals, delicate work…
It just give me that little more control.

I have one and can’t remember a time I changed the speed. Not saying I haven’t but it would have been so rare that if there was a big price difference, I wouldn’t but one with speed control.

My Bosch has variable speed but, come to think about it, I’ve only turned the speed down once or twice. I have to agree with PaulDoug in that, if there were a big price difference, I’d probably buy the single speed one.

I have an older 6” Porter Cable. The slower speed will give you more control at times. That is useful for what I do.

I change the speed on mine. High speed for initial sanding, lower speed for final sanding and more delicate work.

I use variable speed for edge sanding, or for smaller parts. It is easier to control, and gives you more options. My Bosch has variable speed, but it is underpowered anyways. I wish my Dewalt had variable speed.

I have a right angle Porter Cable and I have used it with very fine sandpaper sanding really small stuff where maximum control and minimum material removal is needed.

I have four RO sanders. One does not have variable speed which I keep 60 grit paper on it for
hogging off a lot of material. The three others have 80-100-120 grit papers. Since they are used for
different applications they are at different speeds. And I do adjust the speed depending on the wood
I’m sanding. One advantage to have multiple sanders is that I don’t have to constantly change the sandpaper
which decreases the life of the hook and loop pads.

I have the porter cable variable speed sander also and use the slower speeds for sanding very small or delicate parts.

Hmm fascinating, so it sounds like the majority of people find variable speed helpful when sanding…
  1. delicate surfaces parts/curves
  2. different woods (lower speed for softer wood?), for better control over sanding rate

Also I’m not in the market for a new sander, but rather just a question of hypothetical benefits/practical uses of variable speed. Thanks everyone for sharing…

woodchucker, have you tried using a spray adhesive on your sanding pad of your 1/4 sheet sander? I have never done it myself, I don’t even own one, but I have read other forums saying that it really helps to keep your paper from tearing up and binding.

Have your say...
