I won't even pretend to have a quantitative answer as to why I'm so hypnotized by the dual screw design, and I've read the arguments against it on the forums, so I consider myself forewarned. I certainly won't be saving any money going that way, either, given the need for an extra screw assembly, etc.
Still, that's the design that satisfies whatever intuitive sensibility I've developed over the years regarding jigs and tooling generally, and I'll most likely be following it. However, the idea of simply making Nate's design with a smaller y axis is tempting, so I'll let that thought settle in a bit. 32 inches should be just enough to mill the guitar neck design I'm going to use.
Plenty of time to make up my mind; issues like footprint, gantry height, racking, torsion, backlash, table flex, etc. may ultimately be less important than the total cost of tooling up in terms of time and money. Nate's design seems more than capable of the accuracy needed for what I'm going to do.
