Z axis power feed advice sought

[metric_taper]

I had intended to post a photo of my Wells-Index 645 vertical power feed;

I made a custom knee crank replacement, as the original had the long curve to miss the cross feed wheel. I also could not reuse the original feed dial, as the next photo shows it's uniqueness, and does not match the diameter of the power feed Bridgeport type feed dial, that's reused as part of the install. Your vert lift probably does not have this issue, as if import or 'other' they probably copied Bridgeport, as all these power feeds seems to use those dimensions for install design.



This is the issue with my mill, nice styled feed dial.
