    Thanks for the feedback guys.

    Last query on the limits of thread in 5mm thick aluminium... When attaching the supported round rails on top of the beam on the X-axis is it then necessary and best to run a length of thicker flat bar through the box section to take the bolts?

    I've decided to go with Jazz's GREEN design for the Y-beam..... It's a great KISS solution... can't for the life of me recall why I dropped the idea in the first place! Have attached updated pics.

    Although my gantry end plates are only made from 9.5mm angle-section.... it helps makes the design compact and build easier what with my current limitations... I'm hoping that with the end plates and gantry being relatively squat, this will be rigid enough. Or should I include some bracing to the angle?
