I mean D4 to be so long /260-300mm/ that router bit stays inside it. Its called -overhang/ how far from X rail is the spindle nose. There is center of gravity also. The nearest the bit to the center of gravity, the better. Ideally all should be designed so that is perfectly balanced .

you could read basic info about forces there http://www.cncroutersource.com/do-it...NC-router.html


But you could do it out of this concept as you like, if using Hiwing 20 rails and carriages. They are so strong that overhang is not a problem. Just i like things to be perfectly balanced and engineered
