I thought that I would have a go at turning a sphere and hollowing the midle out of it keeping it in one piece rarther than turning two halfs and glueing them back together.
It was all going well until i heard them fatal words ( just one last cut, just one last cut ) as it was a test piece i had turned it near round and hollowed it out to the near round.
Instead of leaving it i decided to put it back on the lathe and turn it to the round, ouch and lessn learnt it is now bigger on the inside than the outside in one place.
I did put some decoration on this one as a test and i hope that someone learns from my mistake. Les
