"If you wind your own springs, you know that sizing the mandrel for winding is generally done by guesswork. Kozo Hiraoka, writing in HSM, has produced a formula for calculating the required mandrel size that should help to get you close. I coded his formula to make it easier to use."

"My good friend, Gene Rutkowski, up in Seattle, wrote a spring design program while building his locomotive. I've converted it to C and am making it available here."
They could be good supplemental information to Tom's nice video.

If you read the intro on the files page in the above links, Marv explains his programs don't run under Windoz. He recommends a DOS emulator program called DosBox. The spring programs run fine on Windoz under DosBox.
I have not seen Kozo's programs and don't have access to the mag article. Is there somewhere I can download it?
