I am building a box and would like to countour the outside of it to be roughly the same as a Bombay chest. I am not certain how to best achieve the concave portion of the countour. My first impression is to secure a vertically oreinted router bit that has a "pear" shape. The other idea is to use a bit shape that is completely round (e.g. globe shaped) and then merely do some sanding to achieve the proper contour.
Is there such a thing as a "pear-shaped" router bit? Any other ideas on how to achive this contour?
