Well here goes... Aluminium frame router design

[CharlieRam]

If your mostly cutting wood then this design will be fine but if your planning to cut aluminium often then I wouldn't use it.

Yeah I thought as much, What about this one, I have also reduced spacing on Z and Y by 50mm giving the machine an effective travel of 800 x 650 x 150. I thinK this should be a lot more sturdy.
I haven't thought much about the base yet tbh, I was thinking of either having it mounted vertically to save space (if I decide to make X longer) or just build an aluminium 8040 table, I am assuming I will need to brace up the bed of the MC to stop twisting?
For the M/C bed I was going to use 15mm MDF and then place a 5MM aluminium sheet on top of that, drilled and tapped for t bar/ slots?
What do you think, Still not sturdy enough or will it work?
