Claim Text:
1. A unitarily removable molding apparatus having at least four elongated surfaces, the molding apparatus comprising: a first elongated surface separated from a second elongated surface; a plurality of coplanar aligned and spaced hollow pockets descended from said first elongated surface to a descended surface shorter in depth than said separated thickness from said first elongated surface to said second elongated surface; a plurality of coplanar aligned and spaced projections extending beyond said first surface from or preferably through said descended surface of said hollow pockets, wherein each said projection has a common center with one said hollow pocket, and wherein at least one passage is provided between each said descended surface of said hollow pockets to an elongated passage within or upon said second elongated surface; and a third elongated surface separated from a fourth elongated surface, wherein said elongated second surface contains a plurality of coplanar aligned and spaced conically shaped tapered openings, said conically shaped tapered openings decreasing in diameter in a direction as moving from said elongated second surface to a position short of said descended hollow pocket surface, wherein a center of said conically shaped openings aligns with a center of said hollow pockets, and wherein each said projection has a conical end segment matching a tapered angle of each said conically shaped tapered openings ending at said position short of said descending hollow pocket surface, wherein each said projection has a segment of constant diameter from said position short of said descended hollow pocket surface to said descended hollow pocket surface, closely matching an opening extending from said position short of said descended hollow pocket surface to said descended hollow pocket surface, wherein each said projection contains a passage extending through said conical end segment and said segment of constant diameter, each said conical end of said projection is wholly recessed within said second elongated surface, and each said conical end of said projection is secured with TIG weld tacks.
