Got a lathe? I attended a recent demo where the demo'er advocating drilling long holes (for things like lamps) using a spade bit where the spade profile had been ground to more of a pointed oval shape. His claim--I have not tested--is that given the forces on the drill bit from wood that is moving faster/slower relative to the drill bit because of the rotation of the lathe, that the bit is naturally self-guiding to the center.
I second Eric's suggestion. If it is not already glued up, laminate together pieces that you can drill perpendicularly with your drill press. Then use a 1/2" diameter steel rod to align the subcomponents together in the complete glue up. Drive the rod out after the glue dries.
