No very difficult to build that way and too weak in key areas. Not enough bracing at bottom and the top rails will be very hard to get on same plane.
Look at this and Work along the same lines as this with regards bracing etc but without the adjustable bed if not required with slightly lower sides and you won't go far wrong.

This machine is in progress and will have 4th axis on the end when it's finished.

Also Why 350mm Z axis travel.? That is quite a lot and if your planning on cutting anything hard you'll get lots of flex and resonance giving a poor finish.

Edit: Opp's Eddy beat me too it.!!. . . or like Eddy's done. . Lol

Why 350mm? Because the whole idea of building the machine is it to perform two tasks, firstly to cut forms from 18mm Birch Ply and then when the forms are assembled by stacking one on top of the other to mill to the final shape. If I cannot have 350 mm of cutting depth I am throwing money away.



I was hoping to be able to store ply sheets ( I buy 10 at a time) under the bed. However with all the triangular bracing everywhere that also appears to be a No No ... Oh well back to the drawing board.
