Congratulations on your new lathe purchase. Are you planning to build your own control system for integrating the VFD into the lathe?
I'm not clear on your existing level of experience with a metal lathe, but here are my suggestions on YouTube video resources that are ideal for learning mill and lathe skills - in ascending order by level of sophistication. They all have something to contrubute, but these are my favorites, and there are many others. If I had to pick one as a beginner, I'd watch Joe Pieczynski from his first video onward in spite of his sometimes pedantic style. Second on my list would be Keith Fenner from the beginning.
