Mike (GNTKlR) and digest and discuss Carter designs. Any links to Imperialclub.org will fail. I don't know why but they dropped the .org and then the .com mirror site. Now they use a .info address. Most of the documents are still there.

Need to measure and plot that curve.
Then we can figure out where to go.
