John: This, of course, would make the kerf-width same in any direction, but
it would leave "feathered" track-edges, still. Perhaps dipping the
just-milled boards in etchant for five minutes after mechanical-etching?
But I fear all this talk of "tiling boards" has many "in here" conjuring
machines with sloping "tables" and springs or whatever to overcome the
effects of gravity, i.e., complex 'chinry! Can't we change the TITLE of this
thread to "sloping quill-motor"? Better yet: "Home-brew PCB drill/router
with tiltable quill-axis"!!! Jan Rowland
