An apparatus and method for fabricating accurate, numerically defined curved surfaces and volumes comprising a skeleton framework having a plurality of bulkheads fixed in spaced relationship with each other, each of the bulkheads having an equal number of boreholes passing through the outer perimeter thereof so as to provide a set of selected boreholes. A flexible spline having a memory is passed through each set of mating boreholes and is secured with the boreholes after the splines have reached their static states. The resultant framework is encased in a cured polymer and the polymer is trimmed and faired between the outer edges of the splines.

A method for fabrication of a skeleton framework defining three-dimensional curved surfaces and volume comprising providing a series of bulkheads at spaced intervals; defining a set of points substantially adjacent the perimeters of each of said bulkheads; providing boreholes through said bulkheads

A method for fabrication of a skeleton framework defining three-dimensional curved surfaces and volume comprising providing a series of bulkheads at spaced intervals; defining a set of points substantially adjacent the perimeters of each of said bulkheads; providing boreholes through said bulkheads at each of said points, each of said boreholes providing an open channel across the perimeters of said bulkheads; passing a plurality of flexible splines having memory through substantially mating boreholes in adjacent bulkheads; and securing said splines within each of said boreholes after they have reached their static state.
