Hope this helps.

Also, with all due respect, I don't think this works. I came across some guys suggesting this idea when I was developing my plans to make radius blocks. Here's the problem. As you increase the angle to which you skew the wood across the table, you increase the radius you create. (I know it's elliptical, but I doubt many people would ever know the difference on an actual guitar.) The greatest amount of skew you could possibly achieve would send the wood directly parallel to a straight cut. You would, in effect, be running the wood horizontally across the table saw, rather than vertically, as you normally might. This would give you the largest possible radius the blade can achieve. And that radius is the exact radius of the table saw blade. For most of us, that's a 10" radius. And I don't think it would work very well. Table saws are scary, even when they're used as intended.
Correct me if I'm wrong.
Incidentally, the drill press planer works, if an elliptical radius is ok. I think most people set it up with trial and error, measuring the radius they create after the cut it, and then making small adjustments.
