It's funny you say that. I rolled my mandrel on a flat surface and it is not more bent then the brand new 1/4" steel rod that I bought from Lowes. I order another mandrel from PSI which hasn't arrived yet. I will try the same.
I wonder if the problem is with the locking nuts holding the mandrel rod.
Anyway, I turned a coffee bean pen tonight and all was fine (other then the darn beans falling out). I took my time, went really light with the tools, sharpened the carbide blades on a Smith diamond stone (great advice from Oldman50), and only turned one barrel at a time. I could have built a rocket ship in less time.
All of the advice I receive achieved better results!
Thank you.
