Wanting some down time I was rereading some older posts and I came across this one.
I began rethinking spirals, and using what I have learned since this thread had been started, I was able to come up with a smooth spiral, no adding arcs together, just one simple smooth spiral.
The key is to create a polar grid. At the desired angle and radius connection points start a spline and continue the spline connecting at other continuous angle and radius points as depicted in the attach illustrations.
I haven't figured out how to size the spiral to fit the need but that's for another day.
