Hi,
Another LS130 use / method.
For easing edges I usually use the flat pad (or a radius pad to straddle both edges at once) with 150 grit Rubin. But Dave Ronyak has come up with a different method which is posted below. I have not tried it yet but it certainly seems like it should (does) work very well. And will take out blade marks as well.

"When sanding the edges of (birch) plywood with the LS 130, I first sand using the hard flat pad - the one that is supplied with the basic LS 130 package, using 80 grit Rubin, then I peel off the Rubin, apply the soft interface pad and reapply the 80 grit Rubin. If I want a significant amount of rounding of the edges, before changing to the soft interface pad, I will intentionally tilt the sander to help aggressively abrade away the edge, then repeat this motion after installation of the interface pad. Because I have been focused on making shop cabinets, I have not gone above 150 grit abrasives.
The next time I try this, I may try some Cristal abrasives. I used Rubin because that is what I had in stock, and it has a durable thick backing that does not easily tear through. In contrast, if you try the same motions of the LS 130 on sharp edges using Brilliant abrasives, they are likely to tear through due to their much thinner and thus weaker backing.
