I've just been having a look at the Solsylva site, and quite like the overtable design in terms of its structural advantages for the gantry movement, but then I was thinking, what about the table fixing? surely rather prone to not being completely flat to the table if you see what I mean?
So, firstly, looking for thoughts on if this method is any better or worse than any other design.
Also, would like thoughts on what sort of tube diameter you would use for an unsupported rail of about 3ft which will have a medium sized router as the cutting source - tube will be hard stainless 1.5mm wall thickness.
Thanks!
