buttons. Internal, expansion, will be close to the stated size of the disk.

axle system can be disassembled to facilitate exchanging interface plates based on the desired jaw size

Buttons are made using virgin silicone resins and soft enough to insure a firm grip while being non-marking. Buttons do not contain any oils which are known to be imparted to the material being held. ion. The modern longworth chuck is manufactured in the US.

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. The accurate CNC machining of this chuck ensures the phenolic 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 finalize the grip on your work piece.

The Longworth Chuck has a steel mounting plate measuring 2-1/4”x 3/8” thick. This lets you use your existing 4-jaw scroll chuck, w/ #2 jaws for gripping the mounting plate, holding the Longworth Chuck to the lathe. This eliminates the need to change chucks or to switch out jaws and/or move buttons.
