I realize that it wasn't the greatest for the lathe (especially the ballscrew on the tailstock), but we rarely broached anything thicker/more intense than 1/2" aluminium, and didn't seem to have any issues with the lathe.
the biggest problem is with the spindle bearings, not the nut in the tailstock. The spindle bearings are not designed to support an axial load when not rotating.
