Thanks, Ken. Not exactly a glowing review. But at least now I know where to find one if I have to try it myself.

: I got one at a local woodworking show a while back, from a Canadian company
: called Stockroom Supply. They call it a flex adapter. It is about
: 1/2" thick, soft foam, with hooks on one side and loops on the other,
: and predrilled with holes for dust collection. You just stick it onto the
: bottom of your ROS, then stick your sanding disks to the other side.

: I tried it for a while, but found that the foam was too soft to get any bite
: with the abrasive. It didn't seem to be doing anything. I switched back to
: the curved cabinet scrapers.
