Well, by this criteria I’m a hack too. LOL
I do have an old South Bend 9” lathe and an ancient small horizontal mill. I can do what I need, but I’m no machinist. I build all of my own engines and have for a few others too, but I’m not an engine builder. I also build my own transmissions and do all my own fabrication, but don’t claim to be either.
Yep a hack!
