Claim 6:
7. A modular tooling configured to manufacture multi-spar torsion boxes of different web heights, the modular tooling comprising:
a mandrel module including a hollow beam geometry which comprises a first base, a second base opposite to the first base, and two walls extending between said first base and said second base, and
at least one spacer module configured to couple with the mandrel module, wherein the at least one spacer module is selected from a plurality of spacer modules each having a common width and a different height;
wherein a web height of a multi-spar torsion box being formed by a stack of the mandrel and the at least one spacer module is defined by the stack,
wherein the mandrel module comprises a first mandrel module member and a second mandrel module member configured to couple to the first mandrel module member,
wherein the first mandrel module member comprises a first mandrel module base and two first mandrel module walls extending from said first mandrel module base,
wherein the second mandrel module member comprises a second mandrel module base and two second mandrel module walls extending from said second mandrel module base,
wherein a first of the first mandrel module walls is configured to abut a first of the second mandrel module walls,
wherein a second of the first mandrel module walls and a second of the second mandrel module walls each comprise a distal end configured to couple with at least one spacer module, and
wherein said at least one spacer module is interposed between the distal ends of the first and second mandrel module walls.
