I doubt this has ever been discussed here before. A few years ago I went to a lecture by Claire Van Vliet (our Great Mother) and she mentioned the physical problems she inherited from printing on a Vandercook for some five decades. These were spinal in nature, as I recall. Never thought much about it before but I just found out, after some thirty-six years at the wheel, that my rotating cuff (right side) is shot. Not all that pleasant a pain. I’m assuming the worst. Vandercook love.
