The power feeds are pretty much universal in my experience. I had to adapt one I purchased from Precision Mathews for my full size Sharp knee mill.
It took some time to get it right.
Had to use the lathe to make a spacer, I shortened a bushing too.
The lead screw support is specific to Sharp and is not standard. There is an extension that I had to purchase also.
The pic is of the left side showing the extended support. Both sides are the same. The drive is on the right. I don't have a pic.
Works great now.
Pay attention to the gear backlash. Since these are not a perfect fit they come with a shim pack that must be dialed in.
I assume the longevity would be compromised significantly if there was not a good fit.
Little tiny gear teeth.
