I have the Boxford ACL which I think was the toolroom equivalent of the TCL.
Rather different animals – the ACL was CNC modified version of the geared head "industrial" lathe where the TCL160 is a small bench top educational machine ?
As the machine has been refurbished, I shouldn’t have any reliability issues?!
Define "refurbished" ! " "Refurbished" to some traders is removal of visible rust and a badly applied coat of paint.
You would need to ask / see what has been done and how well. Same goes for the Mach 3 conversion – quality componets used and installed to the same standard as the Boxford original equipment, or cheapest no-name stuff off Ebay lashed up with bell wire. Both may "work" when demonstrated !
