Hi,
I need a critique of this decision.
What do you think?
this might work?

I don't see anything that holds the nut into the block when there is axial thrust in both directions. You would need more than the O rings to hold them together. A larger flange with two or three screws through it into the block is needed. The "fingers" of the nut look ok. These need to be allowed to flex but also have constant tension on them.

Not a bad idea at all.. the tension of the O-ring AND the compression of its rubber as well (assuming you get the fit that tight) I'm just thinking that any lube on the screw will climb the kerf and if not rubber friendly, harden the O-ring over time, but no light exposure is good... it should be fine for many years...
This is an example. In fact, the flange nut is held with two screws.I don't see anything that holds the nut into the block when there is axial thrust in both directions.

O-rings are not used to hold the nuts.
O-rings should only implement backlash compensation.
My question is the possibility of backlash compensation. This may work?

That system was used on some of the early Hewlett Packard large frame dot matrix printers. Actually they used circular springs but the same principle.
It works well for removing backlash but is only suitable for REALLY light loads like moving a printhead because it is flexible and elastic in both radial directions, and it's most flexible at the compression point where the actual drive takes place, and that is the worst point to have the flexibility.
