I once worked with a guy that caught a ring on something when he jumped down out of the bomb bay and tore the skin off the back of his finger. Just pealed off a strip all the way from the base of his finger to the fingernail. An Electrician, working on the same airplane shorted out the main battery bank with his wedding ring. Melted the gold ring right off his finger (that didn't do the finger any good either) As a young Airman those experiences convinced me that jewelry and working are a poor combination and even today I automatically remove rings and watches when going to work. -- Cheers, John B. |

I know of a trade school that had its carpentry students building a house, that the school later sold as a fund raiser. I was told that one long-haired student was on the 2nd floor, drilling holes for wiring through the studs in the naked stud walls. He leaned over as he drilled, and his long hair wrapped around the chuck of the drill. The drill pulled his head down fast enough that he knocked his head on the drill, then fell through the open stud space. He was rescued while hanging by his hair about 8 feet above the ground. -- - Frank Krygowski |

Depending on how much hair the drill grabbed I would have expected to find the guy on the floor with a nasty red place on his scalp where the hair got pulled out :-) When I was in the A.F. they were almost fanatical about safety. You could actually be demoted for failure to comply with the safety manual. When I retired and went to work for a civilian company I found that while they gave lip service to safety they were actually far more lax then the A.F. -- Cheers, John B. |

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 |

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. |

If you're thinking of buying a mill, either get one with servo drives, or one that is easily converted to CNC by adding servo drives. (I don't like steppers). CNC makes things much easier. That also means ball screws for the table. If the machine is sloppy when operated manually, it will still be sloppy when driven by a computah. As for the safety lecture, it's all good advice. I would roll up my sleeves, or use a velcro strap to keep them in place. The only real accident I can recall was getting a sleeve caught in an industrial sewing machine. Also, if you're using coolant, you'll never be able to keep the machines as clean as the one in the video. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
