This adapter is for a 4" 3-Jaw chuck such as LittleMachineShop.com PN 1698.
See LittleMachineShop.com PN 1917 for a 4" diameter adapter pre-drilled for a 3-jaw chuck.
*NOTE* These 4" chuck adapters require machining on the lathe on which they will be used.
Instructions are included for final turning of the registration diameter on your lathe to insure perfect concentricity
Chris' TipsWOODWORKERS: Our threaded adapters are not suitable for use on wood turning lathes. Please do not purchase them for this application. These adapters require machining on the lathe on which they will be used, and this is impossible on a wood lathe.
