#1 my new center foot system

I've totally rethought my system, i've kept the JAG bracket and the wheels

 I've used bigger theaded rods (8mm), screws and bolts and 2 plates, the upper plate is inox 3mm and the other is aluminum 3mm

and few rubber pieces between the 2 plates (used to absorb a little some vibrations)

Here is the result with the adjustment of wheels inside the center foot
I've made 4 notchs to be able to screw into half moon parts.
