Longworth Chuck Type 2 – Self Centering Chuck used to finish bowl, plate, and platter bottoms
Quickly and easily finish the bottom of your bowl, plate, and platters with a self-centering Longworth Type 2 Chuck for wood lathes.
This is general information for all sizes of the Longworth Chuck Type 2 Basic configuration. The Longworth Chuck Type 2 uses two disks which, when rotated against each other, symmetrically expand or contract to hold your bowl exactly in the center so you can finish turning the tenon away. Use the Longworth Chuck Type 2 as the final step in turning your vessel.
The eight rubber bumpers are kind and gentle to your vessel, unlike Cole Jaws which use hard grippers and may leave marks in the vessel which will have to be sanded out later. You can use your Longworth chuck in compression mode (bumpers on the outside of the vessel as pictured above) or in expansion mode with the bumpers inside of the rim. If you are turning a bowl where the rim tilts inward, as in a calabash style bowl, it may be difficult to grasp the exterior.
Each of the two disks is cut with a CNC from 1/2″ thick HDPE plastic which is an extremely durable type of plastic. It is the same material that milk cartons are made from. Your Longworth Type 2 Chuck will arrive with a heavy-duty steel faceplate already installed. It will be threaded 1-1/4″ x 8 tpi for 16″ and larger chucks, and 1×8 for 14″ and smaller chucks. Complete instructions and a DVD are included with your Longworth Chuck Type 2.
To assure the proper clearance over the bed ways, the actual disk diameter is a bit smaller than the stated size. This allows the wingnuts on the back to clear the ways when rotating even at full maximum capacity.
The Type 2 designation indicates that this version of the Longworth Chuck is compatible with the optional doughnut rings set offered in the Longworth Chuck Type 2 Combo. The Combo includes complete hardware, 1 or 2 large doughnut rings with 8″ or 9″ and 6″ openings, and four smaller rings with openings of 5″, 4″, 3.5″, and 3″ used to accommodate smaller vessels. This offer is for the “Basic” unit only and does not include the optional Doughnut Rings or the wooden bowl.
