After being poured into fifteen-ton ingots also called "heats"the steel was divided into inch by inch by 4-inch blocks, known as "lifts," which were then cut into three equal inch pieces to make them easier to handle.
The cut lifts were sent to the Gary Works in Gary, Indiana for further processing, after which they were each reduced into inch by inch by 0. The helmet discs were oiled and banded into lots of for delivery by rail to McCord or Schlueter for pressing and final assembly.
Each "heat" of steel was assigned a unique number by the smelter, as was each of its "lifts. This unique "lot and lift" number was stamped onto each helmet produced from the discs of a particular lift, and allowed for traceability in case the helmets exhibited defects.
The "lot and lift" number is in reference to the time when the fabricator received the helmet discs, not when they were made into finished helmets.
Lifts of heats were not loaded onto or unloaded from railcars in any particular order, and were often warehoused also in no particular order before being finished.
The helmet discs were drawn to a depth of seven inches to create the rough helmet shape, or "shell," and the edges were trimmed. The edge of the shell has a crimped metal rim running around it, which provides a smooth edge. This is usually known as the "rim".

If the chinstrap were worn, the head would be snapped back, causing the victim to lose balance, and leave the throat and stomach exposed to a knife thrust. Secondly, many men incorrectly believed that a nearby exploding bomb or artillery shell could cause the chinstrap to break their neck when the helmet was caught in its concussive force, although a replacement buckle, the T1 pressure-release buckle, was manufactured that allowed the chinstrap to release automatically should this occur.
