Abstract : This invention relates to the field of tooling spacer blocks or mandrels enabling fabrication of complex structures from individual component elements using diffusion bonding and similar element integrating techniques. This patent application describes diffusion bonding spacer block tooling or mandrels having low physical mass and low thermal mass and specially adapted to the fabrication of airframe component elements such as titanium structures. Alternate uses for the disclosed structure and a plurality of spacer block example configurations and preferred stainless steel mandrel material are included, along with a sequence for using the disclosed spacer blocks.
