So, your adjustment screw will squeeze the threads? If so, it means that while outside turning the force will be taken via the adjustment screws to the cross-slide. I modified my Southbend in a similar way except, the adjustment screw were threaded into the split portion (I simply sawed part of the way through the nut) , so the adjustment separated the parts IYSWIM.
