The Craftsman Copy Crafter lathe duplicator that I bought and that is supposed to be able to copy spindles up to 38″, apparently will only actually do 35″! Grrrr! I have the bar holders out as far as they will go, and probably farther than they are supposed to go (ends of the bars are only haflway in the holders), and when the carriage moves from end to end, the cutter only moves 35″. Where they got this 38″ number I do not know. I am looking at making a shop built duplicator that will be easier anyway. I have some cool pics on the net of things people have built, and I will make my own.
