Yes... let me try to explain the proposed parts not yet posted:


Thruster Bearing | Geared nut | Thruster bearing All within the same inch where the vex gear would be. The thing I do not know yet is how far the screw can go before it needs support bearings when the rod gets retracted. I was thinking maybe 6" (halfway) of placing a bearing there.

I know this video is not driving a geared nut, but it does give me some direction as to what has worked before.

Thanks for the feedback... any ideas about how to solve that would greatly be appreciated.
