The collar on the screw is quite a loose fit in the hole. The hole is about .82" while the collar is about .75". I might attempt to make a ring that I can press onto the collar to take up some of the slack. Wait, I don't have a lathe yet! 
The counterbore in the casting might be big enough to add a thrust bearing. Otherwise I could enlarge it on the mill. Wait, I don't have a mill yet!
I can't win.
