A clamping system can be reconfigured to clamp any of multiple workpieces having differing shapes. The system includes a retention assembly for retaining an inflatable bladder that applies a clamping force to the workpiece. The retention assembly includes a flexible chain of pivotally connected links that can be locked in place to form a rigid assembly that conforms to the shape of the workpiece. The links can be unlocked to allow reconfiguration of the retention assembly into shapes matching other workpieces.

1. A method for clamping a workpiece during a manufacturing operation, comprising: configuring a flexible retention assembly to generally match the shape of the workpiece, said shape comprising a contour, said configuring comprising individually adjusting the relative adjacent positioning of a plurality of links comprising said retention assembly to conform to the shape of said workpiece;fixing the configuration of the retention assembly to form a rigid retention assembly by locking pairs of adjacent links, each pair of adjacent links having corresponding locking mechanisms pivotally coupling the adjacent pair of links;bridging at least a portion of the workpiece with the rigid retention assembly;placing a bladder between the rigid retention assembly and the workpiece; and,inflating the bladder. 2. The method of claim 1, wherein: configuring the flexible retention assembly includes placing a flexible chain of said links over the workpiece to generally conform to the workpiece, and fixing the configuration includes fixing the positions of each of the links relative to each other. 3. The method of claim 2, wherein fixing the positions of the links includes clenching adjacent ones of the links in the chain to prevent relative movement between the links. 4. The method of claim 1, further comprising securing the ends of the rigid retention assembly to a base. 5. The method of claim 1, further comprising specifying and designing the workpiece. 6. The method of claim 1, further comprising procuring the material used to manufacture the workpiece. 7. The method of claim 1, wherein clamping the workpiece forms part of an operation for manufacturing an aircraft subassembly. 8. A method for clamping each of at least first and second differently shaped workpieces, comprising: configuring a flexible retention assembly to a first shape at least generally matching the shape of the first workpiece, said shape comprising a contour, said configuring comprising individually adjusting the relative positioning of a plurality of links comprising said retention assembly to conform to the shape of said workpiece;locking the flexible retention assembly to form a rigid retention assembly having the first shape by locking pairs of adjacent links, each pair of adjacent links having corresponding locking mechanisms pivotally coupling the adjacent pair of links;bridging at least a portion of the first workpiece with the rigid retention assembly having the first shape;placing a continuous single bladder extending a full length between the rigid retention assembly having the first shape and the workpiece;inflating the bladder;unlocking the rigid retention assembly having the first shape by unlocking the locking mechanisms;reconfiguring the flexible retention assembly to a second shape at least generally matching the shape of the second workpiece;locking the reconfigured flexible retention assembly to form a rigid retention assembly having the second shape by locking the locking mechanisms;bridging at least a portion of the second workpiece with the rigid retention assembly having the second shape;placing the bladder between the rigid retention assembly having the second shape and the workpiece; andreinflating the bladder. 9. The method of claim 8, wherein: configuring the flexible retention assembly includes placing a flexible chain of said links over the first workpiece to generally conform to the first workpiece, andfixing the configuration includes fixing the positions of each of the links relative to each other. 10. The method of claim 9, wherein fixing the positions of the links includes clenching adjacent ones of the links in the chain to prevent relative movement between the links. 11. The method of claim 1, wherein the links are Z-shaped and arranged in overlapping, nested relationships with adjacent links. 12. The method of claim 1, wherein the locking mechanism pivotally coupling an adjacent pair of the links comprises at least one of spline gears, a biasing spring, or a bolt. 13. The method of claim 1, wherein placing the bladder between the rigid retention assembly and the workpiece comprises at least partially inserting the bladder into respective channels in the links. 14. The method of claim 1, wherein placing the bladder between the rigid retention assembly and the workpiece comprises placing the bladder within a longitudinal channel of the retention assembly such that the bladder is retained within the channel. 15. The method of claim 8, wherein the links are Z-shaped and arranged in overlapping, nested relationships with adjacent links. 16. The method of claim 8, wherein the locking mechanism pivotally coupling an adjacent pair of the links comprises at least one of spline gears, a biasing spring, or a bolt. 17. The method of claim 8, wherein placing the continuous single bladder between the rigid retention assembly and the workpiece comprises at least partially inserting the bladder into respective channels in the links. 18. The method of claim 8, wherein placing the bladder between the rigid retention assembly and the workpiece comprises placing the bladder within a longitudinal channel of the retention assembly such that the bladder is retained within the channel. 19. The method of claim 8, wherein the locking mechanisms include interlocking spline gears on opposing faces of adjacent ones of the links. 20. The method of claim 19, wherein locking pairs of adjacent links via the locking mechanism includes tightening threaded fasteners for drawing the opposing faces of adjacent links together. 21. The method of claim 19, wherein the locking mechanisms include springs for normally biasing the opposing faces of adjacent links away from each other. 22. A method for clamping a workpiece during a manufacturing operation, comprising: configuring a flexible retention assembly to generally match the shape of the workpiece, said shape comprising a contour, said configuring comprising individually adjusting the relative adjacent positioning of a plurality of links comprising said retention assembly to conform to the shape of said workpiece;fixing the configuration of the retention assembly to form a rigid retention assembly by locking pairs of adjacent links via corresponding locking mechanisms coupling the adjacent pairs of links, wherein the locking mechanisms include interlocking spline gears on opposing faces of adjacent ones of the links;bridging at least a portion of the workpiece with the rigid retention assembly;placing a bladder between the rigid retention assembly and the workpiece; and,inflating the bladder. 23. The method of claim 22, wherein locking pairs of adjacent links via the locking mechanism includes tightening threaded fasteners for drawing the opposing faces of adjacent links together. 24. The method of claim 22, wherein the locking mechanisms include springs for normally biasing the opposing faces of adjacent links away from each other.
