I am in the heavy sanding stage with my Maloof rocker. I have the RAS, which I have used to remove the wood from the seat and other areas, and the ETS 150 for finish sanding. I used a bowl carving router bit to start the outline that I wanted to be the actual seat area and now I want to sand it and soften the hard line left by the bowl bit. Is there a sander with a thick flexible pad that would conform somewhat to the curves at this area as well as other curves that pop up on this rocker?
