I was a draftsman, special tool designer 1979-1984. Here’s a machine I designed after built. The shop was a plastics injection molded place with full assy to auto plants. Myself and 4 guys were the whole drafting dept, then 6 guys in the tool dept, then the bigger parts plant. I was lead designer, had a detailer that reported to me.
Best job I’ve had to learn from, team wise. Everyone and everything matters. If your design had issues, it caused tool shop $$$’s, or worse plant downtime.
