Saw a picture of a quilt rack with curved sides that are not arcs of a
circle. HOw can I create a fair curve about 36" long that isn't merely
an arc of a circle. I'll post the picture on ABPW in a minute - subject
line: Quilt rack.

Use a thin strip of plexigass that is at least 1 1/2 times as
long as the curve. The grain in wood has strong and weak
points and won't always allow for a fare line to be drawn.
The plexiglass is held in place with weights. I have a set
of "Yachtsman's ducks". These are small rubber coated lead
weights with a brass hook on the front. They have a small
handle on back which makes them look like little 3" long
yellow whales. The weights are used to hook into the plex
and then bend it to the desired curve. I suppose you could
use about 7 or so 4 oz. or larger fishing weights and lay them
directly onto of the plex strip.

Do yourself a favor. Find out which *type* of curve you're
drawing first -- after delivering your project is usually
too late. Ellipses, parabolas, catenaries, cardoids, etc.,
can be mechanically generated by appropriate means.
Buy a small french curve (or set). I got a modest plastic set from LV for a
couple bucks ( $5??)
Fiddle on graph paper until you like the result , and then use the graph
paper to scale to your project size.

long ago when i was on the board ,the plex strip was called a spline and the
weights were called ducks. used to "fair" points together smoothly, actuallt
second degree curves...mjh
