Method of making gear finishing tools

Claim 1

THE METHOD OF MAKING HIGHLY ACCURATE GEAR-LIKE HONING TOOLS WHICH COMPRISES PROVIDING A FLAT MOLD PLATE HAVING AN UPSTANDING PILOT THEREON IN EXACTLY CENTERED POSITION RELATIVE TO A CONTINUOUS ACCURATE LATERALLY OUTWARDLY FACING LOCATING SURFACE ON SAID PLATE, POSITIONING A MOLD RING HAVING A CONTINUOUS ACCURATE LATERALLY INWARDLY FACING LOCATING SURFACE IN ACCURATE LOCATING ENGAGEMENT WITH THE LOCATING SURFACE ON SAID MOLD PLATE, POSITIONING A MASTER GEAR HAVING AN ACCURATELY CENTERED HOLE THEREIN ON SAID PILOT, FILLING THE ANNULAR SPACE BETWEEN SAID MOLD RING AND MASTER GEAR AND ABOVE SAID PLATE WITH A FLUID DIMENSIONALLY STABLE UNCURED RESIN COMPOUND, TREATING THE TOOTHED PERIPHERY OF THE MASTER GEAR WITH A PARTING AGENT PRIOR TO FILLING THE ANNULAR SPACE, CURING SAID RESIN TO FORM AN INTERNAL GEAR-LIKE MOLD, SEPARATING SAID MOLD RING AND MOLD AS A UNIT FROM SAID MOLD PLATE, PILOT AND MASTER GEAR WITH SAID MOLD RING EXTENDING BELOW THE BOTTOM SURFACE OF SAID MOLD, TREATING THE TOOTH SURFACES OF SAID MOLD WITH A PARTING AGENT, REASSEMBLING SAID RING AND RESIN MOLD ON A SECOND FLAT PLATE HAVING A CONTINUOUS LATERAL LOCATING SURFACE AND A PILOT RELATIVELY LOCATED IDENTICALLY WITH THE LATERAL SURFACE AND PILOT ON SAID MOLD PLATE WITH THE LOWER PORTION OF SAID MOLD RING ENGAGING THE LATERAL LOCATING SURFACE ON SAID SECOND PLATE, AND THE UNDER SURFACE OF SAID RESIN MOLD LOCATED ON THE UPPER SURFACE OF SAID SECOND PLATE, FILLING THE ANNULAR SPACE WITHIN SAID RESIN MOLD WITH A FLUID UNCURED DIMENSIONALLY STABLE RESIN COMPOUND CONTAINING ABRASIVE PARTICLES, CURING THE COMPOUND TO FORM A GEAR-LIKE BODY HAVING A PERIPHERAL TOOTHED PORTION EXACTLY CONCENTRIC WITH SAID PILOT, AND REMOVING SAID GEAR-LIKE BODY FROM THE MOLD, PLATE AND PILOT.

Claim 2

THE METHOD OF MAKING HIGHLY ACCURATE GEAR-LIKE HONING TOOLS WHICH COMPRISES PROVIDING A FLAT MOLD PLATE HAVING AN UPSTANDING PILOT THEREON IN EXACTLY CENTERED POSITION RELATIVE TO A CONTINUOUS ACCURATE LATERALLY OUTWARDLY FACING LOCATING SURFACE ON SAID PLATE, POSITIONING A MOLD RING HAVING A CONTINUOUS ACCURATE LATERALLY INWARDLY FACING LOCATING SURFACE IN ACCURATE LOCATING ENGAGEMENT WITH THE LOCATING SURFACE ON SAID MOLD PLATE, POSITIONING A MASTER GEAR HAVING AN ACCURATELY CENTERED HOLE THEREIN ON SAID PILOT, FILLING THE ANNULAR SPACE BETWEEN SAID MOLD RING AND MASTER GEAR AND ABOVE SAID PLATE WITH A FLUID DIMENSIONALLY STABLE UNCURED RESIN COMPOUND, TREATING THE TOOTHED PERIPHERY OF THE MASTER GEAR WITH A PARTING AGENT PRIOR TO FILLING THE ANNULAR SPACE, CURING SAID RESIN TO FORM AN INTERNAL GEAR-LIKE MOLD, SEPARATING SAID MOLD RING AND MOLD AS A UNIT FROM SAID MOLD PLATE, PILOT AND MASTER GEAR WITH SAID MOLD RING EXTENDING BELOW THE BOTTOM SURFACE OF SAID MOLD, TREATING THE TOOTH SURFACES OF SAID MOLD WITH A PARTING AGENT, REASSEMBLING SAID RING AND RESIN MOLD ON A SECOND FLAT PLATE HAVING A CONTINUOUS LATERAL LOCATING SURFACE AND A PILOT RELATIVELY LOCATED IDENTICALLY WITH THE LATERAL SURFACE AND PILOT ON SAID MOLD PLATE WITH THE LOWER PORTION OF SAID MOLD RING ENGAGING THE LATERAL LOCATING SURFACE ON SAID SECOND PLATE, AND THE UNDER SURFACE OF SAID RESIN MOLD LOCATED ON THE UPPER SURFACE OF SAID SECOND PLATE, FILLING THE ANNULAR SPACE WITHIN SAID RESIN MOLD WITH A FLUID UNCURED DIMENSIONALLY STABLE RESIN COMPOUND CONTAINING ABRASIVE PARTICLES, CURING THE COMPOUND TO FORM A GEAR-LIKE BODY HAVING A PERIPHERAL TOOTHED PORTION EXACTLY CONCENTRIC WITH SAID PILOT, AND REMOVING SAID GEAR-LIKE BODY FROM THE MOLD, PLATE AND PILOT.
