Topic tags/keywords: sander question

There’s a part called the brake skirt which is what causes the “random orbiting” to happen. It’s made of a rubbery material and rubs against the sanding pad. The bad part of the design is that the brake skirt looks to be a consumable part. It wears down and has to be replaced. The original part lasted close to 2 years and finally wore down right around Christmas. I replaced it and it ran like new again. Less than 2 months later it’s worn down and needs replacing again. Cost is about $3-$6 depending on quantity. Yearly cost is going to be something like $30-$60 a year to run a ROS.

Are all ROS designs like this? I’m wondering if I should sell it and get a better sander. Or, haven’t run the math yet, it might look more cost effective just to buy a cheap sander every time the brake skirt goes bad.

Please advise.

I have had a Dewalt ROS for 10+ years and the only thing I have replaced is the sanding pad.

All of mine are eccentric center. Never heard of one that rubs against something every rotation to make it have a random orbit. I also have only replaced pads, and in the case of my PC, that little round belt/brake.

I don’t know if cheap sanders are the answer. I wore a cheap unit out in 6 months before I bough my Milwaukee. Aside from the lack of durability, the cheaper ones usually lack variable speed and vibrate in the hand considerably more.

Thanks everyone for the info.

@pintodeluxe: Do you have a model# for your sander? I looked at a newer model and it has a brake too.

@Tennessee: I looked at the ridgid, dewalt, and Milwaukee designs and they all had the brake but I looked at the porter cable design and it doesn’t have the skirt. Does the belt need replacing much?

@Dan628: What was it that cause the sander to fail in 6 months? I rarely use variable speed but the vibration would be something I don’t want.

I’m not sure exactly. The pad started wobbling and I thought the pad screws had backed themselves out. I flipped it to find that the screws were still tight, but I could shake the entire pad side to side. Something had worn or broke internally. I brought it back and got store credit. My newer and more expensive ROS vibrates less but does a better job. It’s witchcraft.

Have your say...
