Re: [CAD_CAM_EDM_DRO]Screw drive

Folks!
Yesterday I stumbled upon "Model Engineer's Workshop" magazine.
Besides other interesting staff there was an article on making your own
screw drive as a replacement for a ball screw.
I'm amazed at how easy and inexpensive is to make this kind of drive -
basically its an arrangment of three short screws, belonging to a nut,
around the drive screw. One short screw can be tightened to adjust
the backlash.
It looks like anyone can make this kind of drive in a matter of hours.
Cheap too.
