its almost there
looks a bit tall.... the way i see it, what you gain in wraping your gantry around your bed you will lose on the extra length of your gantry sides (as far as rigidity is concerned)

find a way to keep the gantry side lengths (hight) to an absolute minimum

your X axis linear bearings are a tad close together
off the top off my head i would say you need to be coser to having your X axis bearing half as far apart as your gantry is tall and if not as far apart as you can (if that makes any sense) especially if your looking to cut alli

im pretty sure you will not cut stainless with much joy on any router type machine
