I continued the sketch with a little more caution. I had to make sure my measurements were accurate or the engineer would not understand what I wanted. The machine needed to have the right length and the correct weight. Any lighter and the machine would be too weak and any heavier and I would break under its weight. The helmet needed to contain a large number of mechanisms that wouldn’t break easily as well. It would be a difficult task for the engineer, but not an impossible one to complete.
