Rotating Nut Fixture x2

[Krammer002]

m_c, Are you suggesting something like the housing shown in this design: http://www.mycncuk.com/threads/3340-...5724#post85724 but with the nut rotated so it sits inside the housing similar to this deisign: https://www.youtube.com/watch?v=4unEngqU09A
There also a GrabCad link to the design in the Youtube description...

Yes.

That youtube video is interesting, although they must be using an Rxx (cylindrical screw in) type nut, as the 3D file has a locking collar on the rear, which I can only guess is for locking the nut into the shaft.
Also, they must be relying on the pulley/pulley bolts to preload the bearings, which means you'd have to be very precise with measurements, or rely on shims for adjusting the bearings.

I need to go and sketch a couple ideas.
