ABSTRACT:
A work-holding chassis is constructed of at least one lower manifold/bracket and at least one upper manifold/bracket with fixture plates attached thereto. An optional center manifold/bracket can be included for additional strength. This chassis is light-weight since the center is essentially hollow. In addition, the modular construction allows the components to be reconfigured and reused for sequential applications. The manifold/brackets have any of a number of differing geometric shapes to which the fixture plates may be attached. The manifold/brackets and fixture plates may be customized to have internal plumbing to afford fluid pressure to activate hydraulic clamps, components, etc.
