I have worked in that forge, back in the late 80's. Gawd, I can't express what it felt like to play and learn in there.
I was technically and interpreter for the museum. I was also training as a blacksmith. I had to be an interpreted to get to train as a smith.
Now I live out in SO.Cal so have not been up on recent events, but when I worked there it was a private company with no affilation with the Ford Motor Company. Therefore, I don't think that the museum removed the blacksmith because of the union.
They where closing doors and replacing the human interpreters with plexiglas and voice recording when I was there.
Mike Machnick (sp?) was the Master Blacksmith, he had told me on more than occasion about his fear of being "Shut Down" as he put it.
He made it sound like the museum was gunning for him. Safety issues to visitors and cost is the most likely the reason the museum closed it.
The real shame is the blacksmith is the only one who cares and knows how to take care of that precious equipment. Maintainence in a "moist" state like Michigan in a never ending battle.
