    Looks to me like the z-axis will flop around in a stiff breeze...

    Needs to be captured both top and bottom.

    This sort of linear motion stuff will work (for a time) but obviously precision and rigidity are fairly low. It will certainly struggle with aluminium but you may get passable results in thin sheet for your purposes. how are you intending to drive the axis?

    You will certainly get plenty of opinions on here that what you are building there is not exactly ideal (to put it nicely!), but given that you are basically building it for free, you don't have much to lose other than your time.
