I bought my Mirka CEROS (Compact Electric Random Orbit Sander) 18 months ago. I didn’t use it much for the first couple of months, but have been using it a lot more, especially on sculpted shapes, including Ash Table and Relationship Study.
The CEROS utilizes a Pad Protector, a thin disc of material with hooks on one side and loops on the other (think Velcro). When abrasive discs are applied or removed from the sander, the hooks of the Pad Protector take the wear instead of the sander’s pad. This prolongs the life of the hooks on the pad. When the sandpaper no longer sticks, you only need to replace the Pad Protector.
This video shows the simple replacement of the Pad Protector and I demonstrate the difference between a worn hook pad and a new one. (Duration – 1:15)
