Abstract: Method of universally making waved parts by (a) providing a plurality of wave forming blocks each having a working surface in the form of a conical segment; (b) removably securing a plurality of such blocks to two arcuate supports (preferably discs) with the blocks spaced apart and with the axis of revolution of the block working surfaces aligned with the radius of the support to create a support-block assembly; and (c) facing and accurately bringing together such support-block assemblies with a deformable material (i.e., spring steel) therebetween, the blocks of one support being superimposed over the spaces between the blocks of the other support.
