Abstract
A method of producing a set of archery bow risers having a variety of shapes is taught in which a workpiece is designed having a shape that encompasses each one of the variety of shapes. A set of dies is produced for producing the workpiece and the dies are used to form a set of workpieces via forging, die-casting or composite resin/fiber molding. Finally, a set of bows having mutually different shapes are machined from the workpieces. The method taught avoids the expense of producing a new set of dies for each new archery bow riser design.
Claims12
A method of producing a first archery bow riser having a first shape and a second archery bow riser having a second shape, said method comprising the steps of:
- (a) designing a workpiece having a third shape that encompasses said first shape and said second shape;
- (b) producing a set of production dies for said workpiece;
- (c) using said set of production dies to form a first one of said workpieces and a second one of said workpieces;
- (d) machining said first one of said workpieces to produce said first riser and machining said second one of said workpieces to produce said second riser, thereby avoiding the design and manufacture of one set of dies for said first riser and an additional set of dies for said second riser.
