Torque plates and gen good machine shop

I used to build engines. Then I got my Engineering degree at night. Then Fords and Mopar engines for friends only. When time got scarce and I had more money, Mopar only. In the end I only do my stuff, and I'm retired. How did we do so much when we were younger??
I can appreciate that. I could get more done after work that I can now with all day to do it. But the good part is, I’m getting to do the things I want to do instead of what I have to do.
