Please help with this build Albert

Hi jazz here is a picture of my proposed layout for the gantry is this what you mean.
Also I am trying to work out the hight of travel for z axis I want a good range of possible but I am willing to sacrifice hight for acuarcey. I am thinking along the lines of the more travel for z axis the more strain on y axis when cutting am I right?
Please anyone give comments on my ideas I only need to build this once I hope.
Albert
