Yeah, I saw it, it's not very promising. I saw some youtube videos of some people who've replaced thier Z axis with them, I wonder how they're coping?

Hey Nick

Most of my Threadless Leadscrew insanity in :

http://forums.reprap.org/read.php?14,328230

Got any ideas on how to make accurate Threadless Leadscrew??

Any Ideas I could try?

Got the set up with 12mm rod and stepper driver, DRO
but crappy results.

may just be a bad idea for a accurate Threadless Leadscrew?

Even commercial threadless ball screws are not rated for repeatability. Your data backs that up. The only way forward that I see is making this closed loop.
