Description
Mesta Machine Company found that built-up shafts were safer for use in machinery than the solidly forged shafts because the shaft and the crank pin were finished separately, making the entire product more reliable. Large shafts used in building engines and rolling mill machinery for iron and steel plants were forged in the company’s No. 3 Forge Shop. These parts were transferred to the Shaft Department where heavy boring lathes were used to bore holes through large shafts. During the finishing and assembling stages, the maximum variation of the shaft throughout this process did not exceed 3/1000ths of an inch, plus or minus. The Mesta's Ship Shaft Department was added to the plant near the end of World War I. The department manufactured ship shafts, castings, and other parts used in the shipbuilding industry.
