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
