Raul,
I suspect that the bulb is hollow and assembled as four, six, or eight staves. I would first dry-assemble the staves as overly large blanks, indexing them to one another with splines (locate the splines where they will not show once the stave profile is cut). Disassemble and then bandsaw the desired profile on each stave before glue-up. I have also seen pedestals like these veneered. In this case, you can veneer it one face at a time with a hammer or vacuum bag. The veneer on one face will overlay (butt joint) the veneer of adjacent faces. Or, if you are feeling lucky, you can dry-assemble and fair all surfaces, then disassemble and veneer each stave separately. The angle of the stave edge will need to be extended to the overhanging veneer. You could probably get by with secondary wood, but I would back up the edges of each stave with primary to hide the inevitable ding or chipped corner. I would go with the first method if veneering--it doesn't seem quite as fussy or exacting.
