Homer worked with metal for about 30 years, as a precision sheet metal mechanic. He worked on projects that are now circling the globe or have landed on other planets, and required a security clearance to go to work. Massive, multi-million dollar equipment was used to make things that had to be measured to the hundredths of an inch.
These days life is different. The high precision equipment is not available. What to do?
A dip in the ground, some pieces of wood, a truck tire make the bend just right. And then back to farm work!
