RBB Natural Edge Jamb Chuck
By Ron Brown’s Best
Cole Jaws, Longworth Chucks, and Doughnut Chucks are wonderful devices. However, you always lose 2″ of holding capacity to allow for the gripper buttons or bolts. If you are using a 12″ lathe, you can only hold a 10″ project to finish the bottom. Using the Natural Edge Jamb Chuck you avoid that limitation and can hold projects up to the full size of your lathe! Turn 12″ bowls on a 12″ lathe, 14″ salad bowls and platters on a 14″ lathe and a full 16″ platter or salad bowl on a 16″ lathe. The NEJC also serves as a stand-off Jamb Chuck for use with any bowl, plate, or platter that has an irregular rim. The irregular rim makes it incompatible with conventional Longworth type or Cole Jaw type bottom finishing chucks. We often find this condition in Natural Edge and rough-turned vessels.
We stock this product with the 1-1/4″X8TPI threading only for now, but have available spindle adapters available in the drop box for you if you need different threading for your lathe.
