Indeed, but take it one step further and make your own threaded roller
screws. In one of the groups (not sure I subscribe to about 45) there is a
suggestion on how to make these

I include this link for inspiration; SKF also sells them
http://www.exlar.com/products/linear/roller_screws/roller_screw_oview.html

I have also draw up my own design which I will build as soon as my Lathe is
finished being converted to CNC
