It was clear that Grey was using some skills to move as fast as he could around the room and assemble the parts. The gears were being tested by the apprentices to make sure that they fit together properly and functioned. It was a process that Walker never imagined he would witness.
The speed that runes were carved was also a surprise to Walker. He thought that they needed a significant amount of mana and time to be added. However, here they were being carved with speed and efficiency. Some parts already were inscribed with runes before they were handed. It was amazing to see how accurately they fit together making a continuous network of runes inside the golem.
