The general consensus here is that there is no general consensus. Some
folks say right-tilt is best, some left, some say it makes no difference.
It seems to me, though if you us a table saw for making your raised
panels, that right-tilt would be the way to go. True, the cutoff would
tend to be trapped between the blade and fence (a high fence, most
likely, for raised-panel work), leading to greater potential for
kickback--but with a left-tilt blade, the base of the blade (where it
emerges from the table surface) would in some cases try to bury itself
in the fence if the angle were great enough or the stock narrow enough.
(Easy to picture--hard to describe)
What say you?
