Hi

Can anyone see any problems or design issues with this described below.

Standard re-enforced rectangle box frame made out of 80mm 80mm by 4 mill ( or 100omm ) 2200mm

On top of that, down the X, Two bits of 160mm by 80mm, fixed, bolted to frame. I beleive i can get these true and level, ( with machineing and epox ). I then want to bolt rails ( round or square ) to the top and underneath of the overhang, both sides. Apart from the difficulty of getting the rails level to each other and true

What other problems can anyone envisage. ?

It would seem a very obvious design to give you close to equal forces in most directions but i can not see any machines designed the same way. The problems i have envisiaged

Trueing and leveling for the Rails. ------- think i have that covered
Deflection forces on overhang ------ Theses exceed the possible forces applied by the Z, so not a problem
Nobody else usese this design -------- This is my biggest problem , there are a lot of clever people on here, noboby seems to do it this way -- why.

Fire way with opinions , Am especially interested in anyone that has previously considered and discounted this.
