Joe's 1000x600x200 steel and aluminium router started

Lovely machine. May I ask which aluminium you bought from Smiths? They have loads of different tooling plate names. Alplan, certal, contral etc.

Also, You have mounted your ball screw supports directly to the steel box section. How did you make sure they were aligned and in the same plane? Surely the box section wasn't that flat?

This time I got a piece of KASTAL 300 from Smiths, but tbh all I do is phone my local branch and ask what they have ready to go, so long as it is cast milled plate.

The rails are set on epoxy what was cast in plane. The ballscrew supports are bolted to the steel and shimmed with the ballnut hard mounted to the gantry so it aligns perfectly. I. E. fit ball nut before end supports.

Edit:
This is what I use for shimming, £15 for a pack of different thicknesses from RS, works really well.
