I have tried Paul's mdf disc method with some success but I just cannot get the bowl to remain central no matter how hard I try. Plus, you end up with a nub that needs removing where the tailstock meets because of course the bowl isn't actually gripped by the disc.
That's odd Rob, it can't not be central if you've marked the centre when turning the spigot initially and then use the tailstock centre in that mark ?
You do end up with a small bit left to remove after, I use a sanding pad and arbour either mounted in the chuck or in a cordless drill and it disappears in about thirty seconds !
I do have a very good set of vicmarc cole jaws mounted permanently on a dedicated chuck but I seldom use them due to the inevitable fiddling around relocating the rubber bits which of course are inevitably never set at the diameter you need ! Knowing what I do now I would never spend on a set, they're just too expensive and it's just so much easier and quicker with the disc method, but everybody is different I guess !
