Rotating Ballnut - design ideas

[Jonathan]

Today I cut the pulley teeth into the first shaft, and whilst that was running made the second shaft.

The belt fits (yay!):



I will cut the pulley teeth into the second shaft tomorrow, then I just need to make the part that connects the shaft to the ballnut, and the ring that pre-loads the bearings...and maybe some bits to act as bearing seals.
