Re-chucking bowls and platters for finishing or light shaping has always been something woodturners want to solve. The Longworth style chuck makes it easy. The self-centering scroll operation quickly adjusts to fit the work and tightening only takes a few seconds.
Designed for clamping in a traditional 4 jaw-self-centering chuck using standard 50mm dovetail jaws. It eliminates the time and hassle of removing and remounting chuck jaws needed when using regular re-chucking jaws. Non-marking premium silicone grippers provide pliable yet firm gripping power. Precision cut plates provide ultimate performance and reliability.
Recommended maximum speed is 600 rpm. The chuck size (14") indicates the minimum lathe swing for which it is intended. Maximum external gripping capacity is approximately 2" smaller than chuck diameter. The table below shows the internal and external capacities for the range of longworth style chucks.
