Oneway Mounting Adapter for Stronghold Chucks

Oneway chucks can be used on almost any lathe. These threaded taper-lock mounting adapters, available to fit a wide variety of lathes, center themselves perfectly in the chuck body, which can then be screwed onto your lathe’s spindle nose. Two of the most popular sizes, 1″-8 tpi & 1-1/4″-8 tpi, are cross-threaded right- & left-hand to work equally well on both inboard and outboard spindles. An adapter is required for mounting Oneway chucks. Extra adapters offer a very economical way to use the same chuck on every lathe you own.

Oneway Mounting Adapters do not include screws. The screws to secure the adapter to the chuck come with the chuck .

Note: The Outboard Adapters at the bottom of the list are used for mounting the Oneway Rotary Air Fitting to the outboard of the lathe headstock when vacuum chucking.

Note: The special outboard fitting for Powermatic 3520A & 3520B lathes will NOT work on 3520C lathes.

Note: The special outboard fitting for the Jet 1236 lathe includes a special adapter to fit the lathe and a 1″-8tpi Stronghold Mounting Adapter to fit the Rotary Adapter.
