EDMUND
FITZGERALD FLAG SHIP
I worked with another machinist name Hank Burnard, on the Horizontal Boring Mill, machining what is called the Stern Tub. The Stern Tub is a casting approx. three feet in diameter and Five feet long, which will carry the Ships Propeller Shaft. Hank and I also Machined the Ships Propeller Shaft which is also a large casting approx. twenty feet long and 12 to 14 inches in Diameter using a large Lathe. This shaft was so important that when we got to the finishing cuts on the shaft, We worked 24-hour shifts. Heating and pouring Babbitt
Metal, was another important job. The Temperature was very critical,
around 700/850 Degrees, I remember having to use a White Pine stick
to check the Temperature, when the stick turned brown, the Babbitt was
ready to pour into the mould, which was then machined into a bearing. Thank You.
