12" Longworth Chuck
Those interested in a Longworth chuck for their lathe would usually have to find a set of plans and try to build their own from scratch. Now you can get this high-quality, ready to use, Longworth Chuck fashioned from durable phenolic resin.
CNC machining of chuck ensures the disc plates rotate smoothly for adjusting the clamping diameter of the chuck. The compressible silicon rubber buttons are non-marring and won’t leave any scuff marks on your lathe turnings.
A quick twist of the wing nuts locks the plates together and compresses the rubber buttons to grip your work piece. The chuck can grip your project from the outside (outside compression mode) or the inside (inside expansion mode). Once the gripper buttons are firmly up against your project, secure them by tightening the wing nuts.
