Hi Leo, Not trying to 'disvindicate' you or divert BobMac's thread, but
just to mildly 'microargue'. A revolving Jacobs chuck held _firmly in a
tail spindle might not be totally useless. I'm wondering about using it
to gently stretch or at least not compress a super thin axial grain
spindle turned between chucks.
Of course there are other methods to keep a skinny spindle from
whipping.
