Boy, easy to tell we live in two different worlds. If I couldn't
freehand the curve I wanted, I'd probably just lay out the curve with a
water hose, and trace around it.

Hi Dave, know the feeling. I've built cabinet frames in the past and glueing
them up with biscuits and trying to keep everything straight while clamping
and waiting for the glue to dry. Today I went to St. Louis Rockler store and
picked up the Kreg pro 2000 and got a free video and large clamp (beside the
one in the kit). Just got in from playing with it and it is sure going to be
a time saver not only in frames but several other things.

Stranded THHN wire would work better (more flexible). :-)

Yeah, thin tree branch, whatever. Basically, buying something like
that would be about the last option, for me.

Sounds like the big splines they used to use for laying out ship component
curves. Ever seen how they do that? They used to design the whole ship up
in the lofts of big buildings, on wooden floors. "Loftsmen" were draftsmen
who worked in full scale. After manufacturing, they'd bring the parts in
and lay them down on the loft floor to see if they matched the drawing.
Anyway, the basic geometry was laid down on the floor, and then they'd bring
in big flexible strips of steel that had, at intervals, places where ropes
could be tied. You tied a rope to the spline at a particulat place and
stretched it across the floor to bend the spline in some particular way.
You just kept doing that -- pulling segments of the spline this way and
that -- until you got the curve you needed. You would also use heavy
"ducks" (weights) to establish points that the curve had to pass through.
The spline could be threaded through the ducks left and right, or held
against the ducks by the ropes. The spline would only bend so far, so that
gave you the smoothness for interpolating through your basic points.
When the spline was the way you wanted it, you drew along the edge with
chalk and then sometimes actually cut into the floor along the chalk line to
permanently preserve the curve after you cut the spline loose. When a new
design came along, you had to plane off the old design or replace the
floorboards in the shipwright's loft.
In modern CAD/CAM software you have the same ideas. Mathematical curves
"splines" are given "ducks" and "knots" to control their layout, and the
inherent degree of freedom in the curve dictates its springiness.

You've been reading different books than I have. I never read
about steel splines, ropes, threading thru the ducks, planing off the
olde design or replacing the floor (you did say they chalk the pattern,
easy enough to clean up chalk).
What I read was wood spines, held in place by nailing, at times,
and/or ducks - a lead weight, with a bent wire, that put weight on the
spline, holding it in place.
If you want to try it, here's instructions. Course you may wind up
with a Viking longship, but that's not a bad thing.

what I was doing was too small for a water hose :)

I used some solder like someone suggested, but I prefer the stuff I
bought today. I got JUST the curves I needed.
