So if the ruler was a stupid price how much was the aluminium? Looks like about £31 worth to me...so I guess a stupid price would be £20.

You seem to have laid it out with the Z-axis rails mounted to the Y-axis slide, not the other way round. Was that just for the photo? Putting the rails on the Z-axis so they move up and down and the bearing blocks are fixed is stronger.
