Carl and Dick,
Thank you for taking the time to read and reply to my post.
When working on old longcase clocks I sometimes find myself trying to fit a 150mm long shaft into the lathe for attention.
They can be anywhere from 1 to 7mm in diameter and have various step changes in diameter, plus a gear cog at one end and a larger gear wheel at the other.
They don't always fit back through the chuck, so it can be difficult to provide enough support for them.
I would like to be able to mount the tailstock end in a free-turning Jacobs chuck to give more stability and options.
kindest regards,
David
