I've used a Longworth Chuck mounted on my lathe for years. Using it to center segmented vessel rings is brilliantly simple.Stanley M
The Longworth chuck was developed by Leslie Douglas Longworth of the Hunter Valley Woodturners in Australia in the late 1980s. By adapting it so that it could be used with the Stomper, it is a self centering mechanism that easily and quickly adjusts to the size of your closed segment ring. This is done by using a pair of disks which rotate against each other, drawing in and out a hex-head nut on a series of opposing arcs.
The speed and accuracy of this centering solution seemed to me to be the perfect answer for centering segmented rings around a plunger since the disks themselves are perfectly centered by the Stomper.
