The depth of the scribing point should be set as shallow as possible to minimize chatter. Unlike scribing straight lines, curved work requires you to constantly maintain firm contact of the rubbing collars against the curved surface to minimize wander due to wood grain.
The MG-4 body is CNC turned from solid 360 brass and is designed to fit hands of all sizes. Once turned, it is CNC milled to create the unique profile for holding the steel rub collars needed for curved scribing. The body is an elegant form that perfectly compliments the function. You will immediately appreciate the weight of this tool as you scribe straight or curved lines. It’s one of those tools that always feels ready to work—the hallmark of a great tool. Now you can accurately layout curved tenons and many other joints where curves play a prominent role in the design or function.
The beam is turned and milled from 303 stainless steel. The working distance for straight lines is three inches. For curved work, the rubbing collars will work on any curved surface with a one-inch or greater radius. Working capacity is three inches. Finally, the beam, and the adjustable scribing pin are firmly locked in place with solid brass locking knobs.
