Abstract
An apparatus and method for making paraboloidal surfaces for example for paraboloidal reflector antennas. The apparatus and method provides a rigid annular clamping ring of sufficient rigidity to provide even distribution of clamping forces, to clamp a disc-shaped sheet on a table so that the sheet may be pneumatically deformed while held in position to prevent inward slippage of the sheet during the deforming process.
