I can if I took any pictures. I will look later today. In the interim, I can walk you thru it first, and maybe mock one up to take some pix.

I have a large 90° Angle plate that is probably 10" x 10" x 10". Clamp it to the front edge of the mill bed and then I moved it rearward by less than an inch if I recall correctly. This is because the stem of the ball is on something like an 8° angle to the centerline of the Radius Rods. When you have it pretty close, clamp the yoke at the top to the angle plate, and then use toe-clamps on the forward edge of the mill table to steady the legs of the Radius Rod (-Wishbone) to the Mill. Each leg of the Radius Rod straddled the knee of the mill. Then just use a boring head to machine the ball off of the stem. Follow-up by threading the stem and you are set.
