Description If you have much bowl work, you can quickly pay for a set of center savers with the amount of wood and time you save. You can also produce sets of matched-grain, nesting bowls. What was previously shavings becomes saleable product. The McNaughton system comes in three sizes, each with a specialized tool gate, a steel handle and an assortment of cutters that let you cut everything from shallow bowls to quite deep cones. The mini and standard systems are suitable for bowl diameters up to 10" and from 4" to 16" respectively (depending on the desired shape of the core), and each includes one straight and three incurved cutters. The large system includes one straight and two incurved cutters for cores ranging from 10" to 24". The straight cutters are also suitable for freehand parting. The tool gate, with a 1" post, controls the orientation of the cutters and serves to minimize torsional forces while coring. 3/4", 1 1/8", 1 1/4" and 30mm diameter post sizes are also available. Please contact Customer Service for more information. The combined sets include all the respective cutters (e.g., Mini/Standard includes four mini cutters plus four standard cutters) but share a common tool gate and handle. Instructions included. Made in New Zealand.
