Nova Mini Cole Chuck Accessory Jaw Set
Other NOVA jaw sets can be fitted to the Cole jaws making a combination jaw facility – expanding dovetail facility for mounting bowls/platters and a reverse dovetail for mounting footed bowls/platters. Many advantages over traditional vacuum chucking. Customizable with false wooden jaws.
Certainly also much cheaper method than vacuum chucking.
Better than vacuum systems because small 6 In. to 7 In. diameter bowls do not have enough volume to hold efficiently.
Low cost rechecking alternative for mini/midi lathes.
Grippers are designed to hold with minimum marking of wood surfaces.
Jaws will not cut into your work piece.
Try and avoid straight sided bowls where the grip will be less efficient. best cutting technique is to have a cutting action with the chisel such that much of the force is directed towards the headstock, not across the face.
To ensure best grip, the bowl should have a positive or negative flair towards the edge of the bowl.
While traditionally these type of jaws are used in the compression mode – depending on the bowl shape, the jaws can be used to grip in either the contracting or expanding mode.
System compatibility – jaw fixing profile is compatible across all NOVA chucks and accessories.
