"This design was inspired by a Mr. Longworth from the Hunter Valley Woodturning Club, NSW, Australia in 1989 and to him should go all praise"


This is a self-centring chuck, which will hold the rim of bowls, enabling the turner to complete work on the base of the bowl.


Quite a useful tool for removing all evidence of how a bowl was originally chucked, leaving bowls with screw holes, chuck recesses, etc.


For the correct Chuck Insert size you will need to know the thread size on the desired lathe.


Choose the insert from the menu.
