I have seen a few videos of “eccentric” turning. Hey, I’m adventurous enough to be dangerous so I had to give it a go. Of course, nobody told me it was difficult until after I had had tried it.
So attempt no#1
Way too thick, and the top is eating into the bowl of the goblet.
Attempt no#2
Much smaller and intricate, but too many different sizes. I know where I have gone wrong in terms of the sizes & shapes, so roll on next weekend.
I also turned a carving mallet from yew and sycamore. It is still to be finished, but watch this space.
Back to work tomorrow though, so no more fun with organic materials for a while.

Adventures in Turning 
Hi, love it. did you use the PSI or Sorby chuck ?
cheers
My chuck is a Vesachuck model T. The method is to mount the blank to cut the cupped part, then remount off-centre. Carl Jacobson has a youtube video on it.
It’s quite scary watching the cupped end wobbling around in an ellipse, but light cuts to begin soon centres each new segment.
