Prior the Second World War, the tool and die industry used surface plates made from steel or cast iron, that were meticulously scraped flat by skilled craftsmen. But not long after the outbreak of WWII , the demand for steel and cast iron, both of which were crucial to the manufacture and production of ships, tanks, military vehicles, and munitions, (leading to their classification as "strategic materials") made iron and steel all but impossible to procure.

In the meantime, Ivan started working with the local monument company that had originally employed Velsey. The company had set up its own surface plate division and named it Herman Stone Co. While Ivan was working there, he and his father perfected techniques for producing surface granite plates. Their plan was to go into business for themselves, but first they had to practice a bit of subterfuge. When Ivan's coworkers were observing him, he would incorrectly lap a piece, then quickly correct the surface when no one was watching. In 1941, however, Ivan and his father started the Rahn Granite Surface Plate Company.
