These Live Center Adaptors are used to position a workpiece being held on a faceplate or chuck on a vacuum setup on the headstock. This saves alot of time when reverse chucking a bowl.
They are made to thread on to the Oneway Live Center (3/4" x 10TPI)
They are made from high quality 6061 aluminum. Two flats are milled on the sides to allow for loosening them. An optional wrench is available if needed.
