Your analogy was better 
Oh, I do plan to stiffen this thing up. As I wrote to a fellow forum member who offered to cut V-Slot compatible Y plates for me, I may have done zero cuts so far as my X-Carve is waiting for its X-Controller, but I have done almost a year’s worth of homework. Yesterday I was looking for local 6061 and 7075 outlets and designing in my head plates that are MakerSlide & V-Slot & C-Beam compatible and capable to be driven by either belt or leadscrew.
