1. The math is done already by others. Your eyes will not be good
enough to see small differences over that distance, so forget
"perfect". I gave a method some time back for calculating heights to
the arc at various distances, but it was questioned as to the
usefulness. [I used to teach math, and was *very* good at it, so I
just ignored replies.]

2. Having calculated, and drawn, how will you cut it? You clearly
won't use a radius that large, so a router guide is out. I'd suggest
hand-planing down to near the line for the larger difference from
square, then sanding to the line.

I'm trying to put a _very_ subtle curve on the bottom of some table
aprons.

The height of each arc will be 1/4" above the baseline of each apron.
The center point of the long aprons is 25-3/8ths from each end, and
for the short aprons the center is 9". Like I said, these are going
to be very subtle curves, but visually important and I want them
perfect. ;


How would I compute the radii of the circles I would need to give me
the arcs for each apron?

(Alternatively, is there another method that doesn't rely on how
steady my drawing hand is in order to do this?)
