Model Engineers' Workshop a couple of years ago that used a similar design
of nut. The question I have is whether they are really up to the job of
killing backlash on the ways of a mill, given that they will be sometimes
subjected to reasonably large cutting forces. Are the springs used on this
style of nut really strong enough to make a difference in this sort of
application? If they are strong enough to kill the backlash under normal
cutting forces, what effect does that have on the torque required to turn
Another cruder approach I have seen used is simply to split the nut (sawcut
across the axis of the screw) and to close up the gap by means of a small
axial clamping screw until all of the 'lash is taken up. I haven't tried
this (yet!) though.
