Understand Pad Saver's Anti-Swirl Function

What happens here

Sherry explains that the primary function of the pad saver is to prevent 'swirling' on wood surfaces. Without a pad saver, the center panel of the sander can vibrate excessively, causing the abrasive sheet to 'catch' and 'skip' across the surface, leading to noticeable swirl marks. The pad saver works by absorbing some of these vibrations, allowing the abrasive to move more smoothly. While it significantly reduces swirl marks, it's important to note that a few may still be visible with any orbital sander.

Goal: Learn how the pad saver prevents swirl marks by absorbing vibrations and ensuring smoother movement of the abrasive sheet on the wood surface.
