Abstract
Complementary semi-tubular metal bars of non-porous metal are extruded to form bar stocks of given length, complementary edges of the semi-tubular metal bars are clamped in edge abutment, a series of longitudinally spaced holes are drilled along respective edges through one of said bars and partially through the other, the holes partially drilled through the edges of the second bar are tapped and the bars are screwed together prior to severing individual connecting rods from the joined bars at points intermediate of the screws.
