Happy in a qualified way...there is a tight area in the middle of the shaft, I must have had some deflection when cutting the external thread despite using the travelling steady (or follow rest), I brought the major diameter of the nut out to where I had an acceptable fit over the tight area, still pretty confident the backlash will be reasonable over the rest of the shaft. I had to come out about an extra .004" from where the end of the shaft screwed in easily, to get the middle section to a point where it will be okay to turn by the feedscrew handle. I guess all will be revealed when it is installed and I can see what the backlash is like.
I assume the fat end of your pump centre has a spring in it?
