you aren't an engineer unless you can do mathematics and physics, sorry lad. real engineers can get ceng, a professional legal title. in the uk everyone call themselves an "engineer", including the guy who installs your wi-fi, but they are not. you're a machinist as you just said, which is a technician. machinists make things for me, they don't design things for me, they don't understand the mathematics or physics behind what they're doing outside of an intuitive, experience based, approach, which is very limited.
