"gal turner" may be referring to the Vega line of duplicators; you can see them on Amazon. I know they have a "midi" duplicator that will fit a Jet mini, but it's capacity is 10" (length). They also have bigger ones, but I don't know about compatibility with your lathe. I think it is around $600, but is worth checking out...which is free!! Good luck to you in finishing your project, whatever path you take to that end.
