For Azimuth I use the Hudson Hi Fi and I cut a piece of lighter card stock cut longer then the jig and placed it on top of the tone arm cartridge mount in a effort to simulate the VPI small steel bar to set the azimuth. When I seen the black line was in the center of the card stock across the entire jig that was a good indication that it was good.
It keep rechecking setup every week until I get a confidence its right.
