A pantograph machine for producing a copy of a master model which comprises:

• a first centre;
• a tracing station;
• and a cutting station;
• said tracing station including means for holding and rotating said master model and a tracing head having a tracing stylus engageable with an adjacent surface of said master model, said cutting station including means for holding and rotating a blank upon which said master is to be reproduced and a cutting head having a cutting tip for cutting said copy on said blank;
• means for moving said tracing head and said cutting head through a first arc about said first centre;
• individual means for maintaining said tracing stylus and said cutting tip in respective engagement with the master model and blank respectively, means for translating movement of said tracing stylus in a lateral direction into movement of said cutting tip in a corresponding direction,
• means for imparting a rotary cutting motion to said cutting stylus;
• and means for varying the relative travel of said cutting tip and said tracing stylus in a lateral direction to vary, the depth of cut of said cutting tip on said blank relative to the depth of cut on said master model;
