A 66-inch diameter vertical boring-mill was the first machine used in making these experiments, and large locomotive tires, made out of hard steel of uniform quality, were day after day cut up into chips in gradually learning how to make, shape, and use the cutting tools so that they would do faster work.

After 30 years of working as a boring-mill operator at Export Tool & Welding, Olev found it hard to retire, and didn't until well into his 70s.
