think i missed all the fun here-!

on my build i'm looking to mount the profiled rails to some 120 x 80 x 6 RHS, one side of the frame fixed, the other will be adjustable, and the frame will bolt together to allow for some tweaking and to shoehorn it into where i plan to install it.

will that give me enough adjustment do you think?

also Jonathan, what program do you use for your FEA simulations could be useful for my actual work
