If anyone has read through this entire thread, I guess by now they have figured out that 'machinist' is just a title that means something different to everyone...
'Machinist' is a lot like 'accurate rifle'... some guys aren't happy unless their rifle can shoot one hole groups at 1000 yards, while others are tickled if they can hit a pie pan at 50 yards...
I once had a co-worker tell me that "$30,000 and 30,000 miles don't make you a biker". I told him that was fine with me... I would still enjoy riding my motorcycle whether I was a 'biker' or not.
My department at work has around 90 machinists (job title)... a former boss has told me several times that, in his opinion, I'm the only 'machinist' there... I don't agree with that, and I don't consider myself to be a machinist.
The point I'm trying to make is, it's a title that means more to the person using it that anyone he may be talking to... the definition can be as broad or as focused as anyone wants it to be.
If you enjoy making chips... or if you are making a living and feeding your family by making chips... that is what is important.
Everything else is just a title...
