My B&D ROS was like any other sander. When you turn it on the disc pad rotated very slowly untill you press it against wood. Now the disc starts spinning as soon as I turn it on. It accellerates very fast and then rotates at the very high speed to the point when ventilation holes look like one big circle. I am afraid to use it it is at least few thousands rpm. Should I throw it out or this is a matter of cleaning or lubricating ?

Why not just try it out on a piece of scrap? You have nothing to lose. Especially if you’re afraid to use it as is.

Just have somebody else with their hand on the plug. In case it gets away from you, they can quickly unplug it. Or use a switched power strip. Good luck.

Cheers!

Maybe I can make a circular saw out of it ?

Carloz,

I use Porter Cable Random Orbital sanders and have experienced a similar problem. I found that the synthetic band that wraps around the main spindle and the small idler pulley was broken. Replacing it fixed the problem. This synthetic band is accessed on the Porter Cable by removing the pad on which sanding disks are mounted.

Yep, I also have a PC orbital. The band that slows the rotation breaks every few years, you can spend the bucks for a ‘real’ part or $0.50 for the properly dimensioned “O” ring. “O” rings work just as well in my opinion.

Same here. My Porter Cable did the same thing. I replaced the little belt and it works fine. The belt runs the “random orbit” feature.
