In the September/October 2008 issue of HSM Andrew Wakefield authored an article on cutting dovetails. He presented an excel spreadsheet method for computing X & Y movement. And this was great!

He also referenced a much earlier work on Ball cutting by someone else, and said his spreadsheet calculation method could be used to cut balls or knobs. Well, even though I'm a bit math challenged I tried to do this, unsuccessfully. So, might anyone have a spreadsheet that would calculate the X & Y movement for cutting balls or knobs? I would really appreciate it! Or even a clear description of the formulas involved would work.

Thanks,

Alex
