Advice on Mammoth CNC Router Build - Steel Framed - 2440mm x 1220mm cutting area!

[Wejjmeister]

Thanks for the comments. I have made a few adjustments to the design based on comments made and also my own thoughts (dangerous!)

I have added a second 3m length of 100mm x 100mm box along the top, this gives me around 200mm on the Z axis. The plate of Aluminium on the bed will be 20mm thick and surfaced flat. I will set the rails along the 3m steels on Epoxy as in Jonathan's build so they are as true as possible, and the Bed will also be supported with uprights rather than diagonals, purely because the frame must bolt together and it is easier with uprights than diagonals to do so, without hopefully compromising the overall strength, I can add feet below the uprights if you deem it sensible too?

Let me know your thoughts guys as I would like to start on the frame soon. Ignore the frame for the Z at the moment, its in its very very early sketchup stages and will change A LOT from now...

Thanks in advance!
