hi ian
looks pretty tidy for the money
i dont think it will cut through 1mm alli in one go without complaining but if your not in a big rush i would have thought it would get you there in the end

with unsupported rails you will get sympathetic vibrations kicking in at some point and giving poor finishes (vibration will kick in no matter what rails you use however if you think of unsupported rails as EXTRA large guitar strings and your cutter+cutting force as a plectrum youll get the idea of how this works) this pricipal applies to the whole stucture of course but on this machine the weakest link would be the X axis rails then the Y axis rails then probably your gantry sides, on a machine with supported rails the weakest link would very likly be the gantry sides


changing spindle speeds may help by knocking the vibration out of phase but i would have thought light cuts high spindle speed and single flute cutter would be the way to go on a machine like that

if you take the gamble youll have to report back here, it would be interesting to see how well a £700 ready to go machine would perform
