i'm sure this isn't the best way and i'm as interested in seeing the
responses as you are...however....
I recently built a highchair with tapered legs that flared out. I was
suppose to trim the top by adjusting my miter gauge and blade tilt on the
TS. Needless to say I was also suppose to accurately clamp and glue up the
assembly...anyway...I got tired of messing with it so I laid the top of the
leg assembly down on my TS, took a 1/8" piece of HB and scribed a line all
the way around, inside and out then sanded to the line.
