Re: ground plates ( alternative?)

Hi guys,

seems this can get a little OT, but since I assume that anyone making
a Z axis would need to have flat and paralle surfaces, it does fall
into the intent of the list.

I had planned on using a pair of said plates to mount my rails on.
The flatness would eleminate any power robbing misalignment.

Is there a better way ?

Is that square aluminum extrusion with T slots ( not sure of a name
for it) stiff enough to handle a thin sheet metal cutting router ?
