These Step Jaws are classified as Factory Seconds as they have been previously used; however, they remain in good condition. One set remains like new with all the nickle plating on it and one set is used and shows some inperfections but it is still nickle plated.
 
Step Jaws, designed by the famous Australian wood turner and author Richard Raffan, are used for holding a range of spigot sizes with minimum jaw movement and without the necessity to change the jaws due to its many steps. These Jaws are designed primarily for bowl turning and they are especially useful when roughing out a number of bowls at one time. Boxes are also easily turned using the step jaws. The bottom can be turned by holding the rim without leaving unsightly pressure marks.

The sizes indicated on the drawing are when the Jaws form a perfect circle.  VM120 and VM150 chucks provide approx. 48mm of expansion beyond these specified sizes. All steps on these Jaws have an internal dovetail angle of 14 degrees for clamping and an external dovetail angle of 10 degrees for expanding.
