Robert 123,
What type of bike are you trying to do this to? i have converted almost all of my builds to disc brake front ends. I was gonna do exactly what your thinking about on one of my first hardtails and then I found a kit that worked.
It's on a tzhinternational ct70 clone. I figured it out on the front but now I want to add a cush drive hub to a rim. I'll post pics when I do it. I can weld it but it might need turned if I don't get it perfect
