I must admit that's pretty tasty! Thanks for posting, as it's always fascinating to explore new ways to use tools.
I don't expect you calculated each point manually, so would you show / explain how you generated the toolpath? I would probably use Excel to step through the path in small angular increments and calculate the appropriate X coordinate but it would be pretty interesting to see how you did it.

2 min job with spreadsheet and some copy and paste / replace in NP++
I am to lazy to calculate each line by hand
Maybe I will make some macro functions for this....

Next step after some input from a friend...
Better spreadsheet to generate G-code for different polygons. Needs only few parameters for input and generates tool paths for roughing an finish cut with back plot of the tool paths and the part.

It's starting to look like they are going to have to make a subforum just for suntravels lathe projects. Very nice work. Your threads have shown me ways to use a lathe I had never thought of before.

No. We mortals need him gone from here! He is like a man competing in women's swimming events as a transgender. A God of CNC.
Seriously that is some cool machining. I come from more of a fabricating background so what Uwe does is all new to me and quite impressive but I still don't like him!
