So I turned my first pen after Christmas - turned around 25 or so total during the season - and I got terrible results. I pressed all of the parts in correctly, yet when put together, the pen is bend around the center band. I did notice that the mandrel seemed to be turning the exact same way on the lathe. The bushings did not even seem round when spinning. Generally I wouldn't be concerned, I'd chalk it up to just needing a new mandrel, but this mandrel has only been used to turn five or six pens. Maybe my lathe isn't turning true? Maybe it's time to go mandrel-less? Anyway, please help. I've included a picture.
