I used to work at an Ivy League University, I ran a dept. machine shop.
My boss, at the time, was a published professor. He told me he was as better machinist than I was. I told him I was a tool and die maker.
I came in the shop one day and saw him in back by the Lassey hand tapper. He asked," how do you use this"? I told him he was a better machinist than me, figger it out.
I came in from lunch one day, he was in my shop with a potential assistant. My vertical bandsaw blade was broken and as was the cast adjustable arm on my horizontal saw. He looked at me, thrust something into my hands and said he needed it cut, and scurried out of my shop. I delivered it to his office, withpot a word, after I finished welding up my vert saw blade and brazing the cast arm on my horiz. saw.
He used to give his students keys to my shop so they could work in there after hours. I'd come in in the morning and find broken tool bits in my lathes and mill, tools left out and one time, blood. I reported it but never heard anymore about it. These 'kids' had NO machine shop practical experience.
After this I had enough. I went to the Dept. Chair and told him, almost my exact words, Bob is handing out keys to my shop like beads at Mardi Gras. He giggled a bit but saw I was serious. I kid you not.
I left soon after to raise our daughter.
A few years later, I get an email from my old Dept. Business Manager, I had adopted her as my boss and we kept in touch. She included a link saying that a female undergratuate student died when her hair got caught in a lathe chuck while working off hours.. She, the student, had advanced training in machine shop protocols, whatever that is, but still managed to make a fundamtenal mistake. Sad. I never heard what shut the lathe off. Anyhow my Business Manager said they all finally got it why I was so upset that day.
When I was on the bench and going to night skool for 11 years to be an Engineer, we had a saying....those that can, do. Those that can't, teach. I've been in a lot of places, seen a lot of things and have done quite a bit in my time. The stories I got....
I now am trying to prove that old saying wrong, I am currently an Educational Assistant in a Tech Community College. My first real class is Monday night, teaching Lathe Basics to future Engineers. Rolled up sleeves, no dangling jewelry and long hair restrained.
