A range of about 192,000 Black & Decker random orbital sanders have been recalled. The problem with these sanders (models RO400, RO400G, RO410, RO410K, RO410LW and FS3000ROS; date codes 200701, 200929) is that their platens can separate from the unit or break off during use. Pieces of the platen or the sanding discs can fly off and pose a laceration hazard.

I thought a “random orbit” doesn’t actually spin in a circle at high rpm
Stuart
Random orbit sander platens do rotate at high speeds, but there is also a secondary [random] motion that ensures uniform material removal. The compound action doesn’t lessen the frisbee-potential of the platen should it suddenly free itself or self-destruct.
To confirm this, turn your Porter Cable low-profile sander upside down and spin it up.

It’s some kind of visual illusion to me – it doesn’t even look like it’s spinning, even when I put it on the lowest speed.
In my mind I know it must be spinning, otherwise it wouldn’t actually sand anything…
Stuart
Attach a small piece of a white label to a dark colored sanding disc or make a mark with a sharpie on a light colored disc and then watch how it moves when you turn the sander on. That should help you visualize the rotation and break the optical illusion.

Wow, I just went out and checked my garage and it turns out I have one of these. Thanks Stuey.

Hey John how long have you had yours and do you remember where you bought it?
Stuart
You’re very welcome, glad to have helped!
