From back in the days when machinists wore neckties! They were classier back then. They probably didn't wear eye protection in 1914 either. Yep, googling yields https://www.umassd.edu/about/historyofumassdartmouth/ Things have gotten much safer since then, of course. Safety inflation is real, and obviously not bad up to a point. I taught an intro to machine shop lab (just bare basics) and would come down very hard on a student who omitted eye protection. But I know the full-time machinist in that lab sometimes worked without eye protection, just as I sometimes do on my basement lathe. It's a risk we take based on our judgment of the circumstances. OTOH, I don't think I've ever obeyed the "Never use without eye protection!" warnings that seem to come on things like Harbor Freight screwdrivers. That company probably puts warnings on its rubber erasers. Kind of like this: https://www.youtube.com/watch?v=7gzDC-2ZO8I I put plastic hats in the same category. - Frank Krygowski Back when I was working at it I wore USAF supplied corrective glasses that were also classified as "safety glasses". When I was in High School I worked one summer in a shop that had machines similar to the photo in your UMass reference. The shop belonged to two old brothers and apparently was originally built by either their father or grandfather - my father remembered it being there when he was a boy. The first job that they gave me was making nuts... on a lathe that the cross slide was calibrated in 128ths of an inch. As an aside, one of the brothers had a Henderson four cylinder motorcycle that probably dated to the 1930's sometime that was in perfect like new condition. He would occasionally ride it to work if it didn't look like rain :-) -- Cheers, John B. |
